Product Specification
...```
Note: The product title is quite sparse. The product description is minimal, containing only one image. Since the content is very sparse, I need to generate a professional, detailed product description for the SBI test apparatus based on the title and standard industry knowledge, while maintaining factual accuracy. The image is the only media provided; I need to include it with a descriptive alt attribute. The output must be a self-contained HTML snippet with a style block, semantic structure, and no heading tags.
Let me craft a comprehensive product description for a BS EN 13823 Single Burning Item (SBI) test apparatus. I need to be careful to not invent overly specific false specs, but I can describe typical features of such apparatus in general terms, which is standard for such equipment. However, since I don't have actual specs, I should keep the content generic but professional, focusing on what the SBI test is and the apparatus's role, without fabricating precise numbers unless they are standard to the standard (BS EN 13823 defines the test).
Let me think about BS EN 13823: It's the Single Burning Item test for building products, used to determine reaction to fire. It's part of the Euroclass system (A1, A2, B, C, D, E, F). The SBI test exposes a specimen to a single burning item (a propane sandbox burner) and measures heat release rate, smoke production rate, and other parameters.
Standard details:
- Test specimen: two vertical wings forming a corner (each 495 mm wide × 1500 mm high), and a horizontal specimen.
- Burner: triangular propane sandbox burner with 250 mm side length.
- Heat release: measured by oxygen consumption.
- Smoke production: measured by light attenuation.
- Test duration: 20 minutes (1200 s) with 300 s baseline.
I can mention these generally attributed to the standard. But I should be cautious about presenting them as exact product specs. I can say "designed to comply with BS EN 13823" and describe typical components.
I'll structure the content:
1. Product Overview (heading + paragraph)
2. Key Features / Test Capabilities (bullets)
3. Test Principle & Measurement Parameters (heading + bullets)
4. Compliance & Standards
5. Applications / Materials Tested
6. Image
But the image is tiny. I'll place the image near the top with a descriptive alt.
Actually, the instruction says: "For all media content (including images and videos), preserve the original class="lazy" src="/myres/images/load_icon.gif" data-original paths and retain all existing attributes exactly as provided". The image has no other attributes besides class="lazy" src="/myres/images/load_icon.gif" data-original (given as markdown ), so I'll add alt.
I need to not use h1-h4. Use div.pd-heading.
All CSS class-based, prefixed with pd-. Font sizes in px with !important. Base 14px. Table borders solid (though I may not need tables; could include a specs table). Let me include a specifications table since it's industrial. That would be good. But careful: I shouldn't fabricate specs. I can present the standard's defined specimen dimensions as "reference" — those are from the standard, generally known. Actually, to be safe, I'll include a table of "Typical Technical Parameters" with values derived from the standard, framed as typical. Hmm, risk of inaccuracy. Alternatively, I can make a table of "System Components" which is descriptive without numbers. That's safer.
Let me include a table of system components / modules:
- Test chamber
- Burner assembly
- Specimen mounting frame
- Gas supply and control system
- Heat release measurement (oxygen analysis)
- Smoke measurement (light attenuation)
- Data acquisition and control software
That's factual for such apparatus.
I'll also include a "Test Principle" section explaining oxygen consumption calorimetry.
Let me write clean CSS.
Output requirements: only HTML snippet, start with
```
Wait — the instruction says do not use ::before/::after pseudo-elements for list bullets or icons. It doesn't forbid them entirely, but safest to avoid. My reset includes *::before which is a pseudo-element but just for box-sizing, not bullets/icons. Hmm, "Do not use `::before` or `::after` pseudo-elements for list bullets or icons — list styling must rely on standard HTML semantics only." So it's specifically about bullets/icons. Using them for box-sizing reset is fine, but to be maximally safe I could avoid. I'll just avoid them entirely to keep it clean.
Let me write the CSS.
```css
.pd-wrap{font-family:"Segoe UI",Arial,Helvetica,sans-serif;font-size:14px!important;line-height:1.7!important;color:#22303c;width:100%;max-width:100%;margin:0;padding:0;}
.pd-media{margin:0 0 22px;padding:0;text-align:center;background:#f5f7f9;border:1px solid #e1e6ea;border-radius:4px;}
.pd-media img{display:block;width:100%;max-width:640px;height:auto;margin:0 auto;padding:12px;}
.pd-caption{font-size:13px!important;color:#66727d;padding:0 12px 14px;line-height:1.5!important;}
.pd-heading{font-size:18px!important;font-weight:700!important;color:#0f2c47;line-height:1.4!important;margin:26px 0 12px;padding:0 0 8px;border-bottom:2px solid #0f2c47;letter-spacing:.2px;}
.pd-heading:first-child{margin-top:0;}
```
Hmm, first-child on heading — the media may be first. Fine.
Sub-heading maybe .pd-subheading for sub-sections.
Paragraph: .pd-text{font-size:14px!important;margin:0 0 14px;color:#3a4a57;}
Lists: .pd-list{list-style:disc;margin:0 0 16px;padding-left:22px;} .pd-list li{font-size:14px!important;margin:0 0 8px;line-height:1.7!important;}
Nested list maybe .pd-list .pd-list{list-style:circle;margin:8px 0 0;}
Table: .pd-table{width:100%;border-collapse:collapse;margin:0 0 18px;font-size:14px;}
.pd-table th{border:1px solid #c8d1d8;background:#eef2f5;color:#0f2c47;font-weight:700;text-align:left;padding:10px 12px;font-size:14px!important;}
.pd-table td{border:1px solid #c8d1d8;padding:10px 12px;vertical-align:top;font-size:14px!important;color:#3a4a57;}
.pd-table tr:nth-child(even) td{background:#fafbfc;}
Highlight box: .pd-note{background:#f5f8fa;border-left:4px solid #2b6cb0;padding:12px 16px;margin:0 0 18px;font-size:14px!important;color:#33414d;}
Responsive: add @media (max-width:600px) to reduce heading size, table padding. Also make table responsive by wrapping? Could use overflow-x:auto wrapper. .pd-table-scroll{width:100%;overflow-x:auto;margin-bottom:18px;}
Base font size 14px on everything with !important. Also set .pd-wrap font-size 14px !important and all children inherit... but since !important specified on each element type, fine.
Now content.
Sections:
1. Media (image) at top with caption.
2. Heading: "BS EN 13823 Single Burning Item (SBI) Test Apparatus — Overview" — maybe too long. Use "Product Overview: Single Burning Item (SBI) Fire Test Apparatus"
Paragraph describing: The SBI apparatus is a reaction-to-fire testing system for building products, designed to determine heat release and smoke production under the Single Burning Item scenario specified in BS EN 13823. Used in Euroclass classification...
3. Heading: "Test Principle and Measurement Method"
Paragraph + bullets about oxygen consumption calorimetry, propane sandbox burner, specimen corner arrangement, 20-min exposure, measurements: HRR, THR, FIGRA, SMOGRA, TSP, TSR, flame spread / lateral spread index (LFS).
Careful: BS EN 13823 gives FIGRA, SMOGRA, THR600s, TSP600s. Yes those are correct parameters.
4. Heading: "Key Features and System Components"
Bullets or table.
5. Heading: "Measured Parameters and Classification Output" - table? Could combine.
6. Heading: "Applicable Standards and Compliance"
7. Heading: "Typical Applications and Tested Materials"
8. Heading: "Installation, Operation and Support" maybe. Keep it reasonable.
Let me be careful not to over-claim specific numbers. I'll avoid quoting exact specimen dimensions? Actually those are public from the standard: specimen 495 × 1500 mm wings, 1000 mm × 1500 mm? Let me recall: BS EN 13823 uses two vertical specimen wings, each 495 mm wide and 1500 mm high, plus a horizontal specimen 1000 mm × 1500 mm? Hmm. Actually the standard SBI specimen consists of two vertical wings of 495 mm × 1500 mm and a horizontal specimen of 1000 mm × 1500 mm? I'm not fully certain; the horizontal part is 1500 mm × 1000 mm? Let me not include precise numbers to avoid errors. I'll say "corner configuration of the specimen wings" without dimensions.
Burner: propane sandbox burner, 250 mm × 250 mm triangular. I'll just say "triangular propane sandbox burner delivering a nominal 30 kW heat output". The SBI burner output is 30.7 kW (30 kW). That's well known. I could include it but risk. I'll say "nominal heat output of approximately 30 kW" — that's standard for SBI. Fine, but maybe safer to omit exact numbers. I'll include "approximately 30 kW" as it's widely documented. Hmm, safety. I'll keep it general: "a propane-fuelled sandbox burner positioned at the base of the specimen corner." Good, no numbers.
I'll mention test duration "up to 20 minutes" — BS EN 13823 flame exposure is 20 minutes (1200s) after a 300s baseline. I'll say "a 20-minute burner exposure following a baseline period". That's accurate.
Measurement: oxygen consumption principle; exhaust duct with bi-directional probe for flow, thermocouples, gas sampling for O2 and CO2, and smoke measurement via light source/photometer. Correct.
Parameters: HRR (heat release rate), THR (total heat release), FIGRA (fire growth rate index), SMOGRA (smoke growth rate index), TSP (total smoke production), TSR? For EN 13823 the classification parameters are FIGRA0.2MJ, FIGRA0.4MJ, THR600s, SMOGRA, TSP600s. Also LFS (lateral flame spread) is reported but not classified. I'll mention these.
Also mention "used to assign Euroclass A2, B, C, D and corresponding s1/s2/s3 smoke and d0/d1/d2 droplet classifications" — BS EN 13823 is used for classes A2, B, C, D; A1 uses EN ISO 1182 & EN ISO 1716; E and F use EN ISO 11925-2. Actually B, C, D use EN 13823; A2 also uses EN 13823 as part of it. So saying "contributes to Euroclass A2 to D classification" and E/F via other test. I'll phrase: "Core test method within the EN 13501-1 reaction-to-fire classification system for construction products, supporting Euroclass A2, B, C and D classifications along with the s (smoke) and d (droplet) sub-classifications." That's accurate.
Applications: wall and ceiling panels, flooring? (flooring uses EN ISO 9239-1, so exclude flooring), insulation materials, cladding, duct linings, etc.
Table of system components:
| Module | Function |
- Test chamber / enclosure with exhaust hood
- Specimen mounting trolley and frame
- Triangular propane sandbox burner with gas train
- Exhaust duct with flow and temperature instrumentation
- Oxygen and gas analysis system
- Smoke measurement (light attenuation) system
- Data acquisition and control software
Table of measured parameters:
| Parameter | Description |
- HRR, THR600s, FIGRA, SMOGRA, TSP600s, LFS
Good, two tables might be a lot but fine for industrial. Maybe combine into one table for parameters and use bullets for components. I'll do: bullets for components, table for parameters. That gives variety and includes a table (with solid borders requirement satisfied).
Let me write final HTML.
Image path: https://img.chinax.com/nimg/ea/9c/2215083c0f0f37450e786981232a-600x600-0.jpg
Alt: "BS EN 13823 Single Burning Item (SBI) test apparatus for building material reaction-to-fire testing"
Caption: "BS EN 13823 Single Burning Item (SBI) fire test apparatus for building and construction materials."
Now write all.
Note: no heading tags, no ::before/::after. Lists use standard ul semantics with list-style:disc.
Let me finalize CSS with px !important on font sizes.
Also add `.pd-wrap ul` etc. I'll use classes.
Write out:
```html
```
Then the content.
For `.pd-wrap` — the outer container div. Since the host has a div wrapper already, I'll use `
`.
Content order:
- media (image + caption)
- heading: Product Overview
- paragraphs
- heading: Test Principle and Measurement Method
- paragraphs + list
- heading: System Components and Key Features
- bullets
- heading: Measured Parameters and Classification Output
- table
- heading: Standards Compliance
- list
- heading: Typical Applications
- list
- note: contact/ordering? maybe a note about customization. Keep it: "Available configurations" — better to add a short closing note about bespoke configuration, calibration and support. Fine.
Make sure keywords: BS EN 13823, Single Burning Item, SBI test apparatus, reaction to fire, building materials, FIGRA, SMOGRA, heat release rate, smoke production, Euroclass, EN 13501-1.
Avoid heading tags.
Let me write it.
One more: `alt` descriptive. Good.
Should I add width/height attributes? Not provided, don't invent. Keep class="lazy" src="/myres/images/load_icon.gif" data-original only + alt + loading? "retain all existing attributes exactly as provided" — only class="lazy" src="/myres/images/load_icon.gif" data-original given. Adding alt is required. I'll add alt only. Maybe loading="lazy" is fine to add but not necessary; keep minimal.
Write final answer.Here is a self-contained HTML snippet for presenting the BS EN 13823 Single Burning Item (SBI) test apparatus. It includes product overview, test principle, key features, measured parameters, compliance standards, and applications, styled to match an industrial equipment page.
```html
Product Overview: BS EN 13823 Single Burning Item (SBI) Test Apparatus
The Single Burning Item (SBI) test apparatus is a dedicated reaction-to-fire testing system built to evaluate the fire behaviour of building and construction products in accordance with BS EN 13823. The equipment reproduces the Single Burning Item scenario, in which a specimen arranged in a corner configuration is exposed to a single burning item placed at the base of the corner, while heat release, smoke production and flame spread are continuously recorded.
The apparatus forms a core element of the EN 13501-1 classification framework and is widely used by fire testing laboratories, notified bodies, manufacturers and research institutes to determine Euroclass performance for wall and ceiling products, insulation materials, cladding systems and other construction components.
Test Principle and Measurement Method
The test method is based on oxygen consumption calorimetry. A propane-fuelled sandbox burner is positioned at the base of the specimen corner and acts as the single burning item. During the burner exposure period, the combustion gases are collected by an exhaust hood and drawn through an instrumented exhaust duct, where heat release and smoke generation are quantified in real time.
- Specimen preparation using two vertical wings in a corner arrangement, with the burner located at the internal corner base.
- Baseline recording of exhaust flow, gas concentrations and optical smoke density before burner ignition.
- Standardised burner exposure period of up to 20 minutes, with continuous data logging throughout the test.
- Oxygen consumption measurement to derive heat release rate and total heat release.
- Light attenuation measurement in the exhaust duct to determine smoke production rate and total smoke production.
- Visual and instrumental assessment of lateral flame spread across the specimen surface.
- Automatic data reduction and reporting of classification parameters after test completion.
System Components and Key Features
The SBI apparatus is supplied as a complete, integrated test system. Typical configurations include the following modules, which can be adapted to laboratory layout and throughput requirements:
- Test chamber and exhaust hood — an enclosed test area designed to capture all combustion products and direct them into the exhaust ducting without leakage or unwanted dilution.
- Specimen mounting trolley and frame — a rigid, heat-resistant frame that holds the specimen wings in the correct corner geometry and allows rapid, repeatable specimen loading and unloading.
- Triangular propane sandbox burner — the single burning item, with a calibrated gas train, mass flow control and safety shut-off for stable and reproducible burner output.
- Exhaust duct instrumentation — a bi-directional probe and differential pressure transmitter for volumetric flow measurement, combined with thermocouples for gas temperature monitoring.
- Gas analysis system — oxygen and carbon dioxide analysers with sampling probe, filter, pump and moisture removal, providing the data required for oxygen consumption calorimetry.
- Smoke measurement system — a white light source and photodetector positioned across the exhaust duct to measure optical density and derive smoke production parameters.
- Data acquisition and control software — a dedicated platform for instrument calibration, test sequencing, real-time data display, automatic calculation of classification parameters and generation of test reports.
- Safety and interlock system — gas leak detection, emergency shut-off, ventilation monitoring and over-temperature protection for safe laboratory operation.
Measured Parameters and Classification Output
The apparatus delivers the full set of parameters required for reaction-to-fire classification under EN 13501-1. Key reported values include the following:
