EN 1568 High, Medium, Low-Expansion Foam Liquid Testing Instrument
This precision testing instrument evaluates foam expansion ratio, 25% drainage time, and 50% drainage time for high-expansion, medium-expansion, and low-expansion foam solutions. Featuring stainless steel construction, high-precision flow control, and automated timing systems, it ensures accurate, repeatable results for foam concentrate manufacturers, fire safety laboratories, and regulatory compliance teams.
Application Scope
Specifically designed for evaluating foam expansion ratio, 25% drainage time, and 50% drainage time of high-expansion, medium-expansion, and low-expansion foam solutions. The system supports international standards including ISO 7203-1-2, EN 1568-1-2-3, UL 162, and NFPA 11.
Compliance Standards
This equipment meets the following standards for determining foam expansion ratio and drainage times:
GB 19156-2019 "General Technical Conditions for Fire Monitors" - Section 6.4.4.1
GB 20031-2005 "Foam Fire Extinguishing Systems and Components" - Section 6.20.2
UL 162-2024 "Foam Equipment and Liquid Concentrates" - Section 10.2
EN 1568 Series:2018 "Fire extinguishing media - Foam concentrates"
NFPA 11-2024 "Standard for Low-, Medium-, and High-Expansion Foam"
ISO 7203 series:2019 "Fire extinguishing media - Foam concentrates"
Pressure Control
Proportional control valve and electromagnetic flowmeter ensure stable liquid supply pressure (0.3-0.65 MPa), compatible with ASTM D1881 test conditions.
Technical Specifications
System Composition
Standard compressed air foam system with high, medium, and low expansion foam collectors and foam separation tester.
