ISO 5659-2 0-924 Six Gear Automatic Shift Plastic Smoke Density Testing Machine

Overview

The plastic burning smoke density tester is a new test equipment for measuring smoke density, which is based on the technical conditions stipulated in the national standard GB8323.2-2008, which is suitable for measuring the specific light density of smoke produced in the combustion of plastics, and the maximum light density is the test result. It is used to assess the smoke performance of plastics under specified conditions. Conforms to GB8323.2-2008 plastic-smoke Generation-Part II: Single-chamber method for the determination of smoke density test method and ISO5659.2-2006 "plastic-Smoke Generation-Part II: Single-chamber method for the determination of light density". The whole instrument consists of a closed test chamber, a photometer measuring system, a radiation cone, a combustion system, a igniter, a test box, a stent, a temperature measuring instrument, and a smoke density test software; the circuit is developed with single-chip microcomputer, with high technical content and stable performance. This instrument is suitable for all plastics, also applicable to other materials evaluation (such as rubber, textile cover, paint, wood and other materials), the plastics industry, solid materials industry, production plants and research laboratories widely used.

Main technical indicators and working conditions

The main technical specifications and working conditions of the equipment are fully based on the technical conditions stipulated in the national standard GB/8323.2-2008, in line with the GB8323.2-2008 "plastic-Smoke Generation-Part II: Single chamber method for measuring smoke density test method" and iso5659.2-2006 Plastic-Smoke Generation-Part II: Single-chamber method for the determination of light density, and according to the above standards stipulated in the terms, technical indicators and technical requirements as the basis for the equipment performance evaluation, acceptance conditions and acceptance criteria.
