Safety Helmet Flammability Tester

Product Introduction:

Safety hat flame retardant performance tester for safety hat flame retardant performance test, high degree of automation, easy to operate, widely used in safety hat manufacturers, major quality inspection units and construction engineering testing stations.

According to the criteria:

GB/T 2811-2007 "Hard Hat"

GB/T 2812-2006 "Safety Helmet Test Method"

GB/T 38305-2019 "Head Protection Rescue Helmet"

Product Advantages:

Measures Critical Safety Property: Quantifies the flame retardant performance of safety helmets, essential for protecting wearers in environments with fire hazards.

Standard Compliant: Designed to meet relevant national standards (GB/T 2811. GB/T 2812. GB/T 38305) for safety helmet flame resistance testing.

High Automation: Features a high degree of automation, ensuring consistent test execution and ease of use.

Provides Objective Timing: Includes precise timers for measuring afterflame and afterglow times.

Uses Standardized Flame Source: Utilizes a Bunsen burner with specified dimensions and allows the use of standard test gases.

Suitable for Safety Hats/Helmets: Specifically designed for testing head protective equipment.

Widely Used: Adopted by manufacturers and testing/inspection bodies in the safety helmet industry.

Product Features:

Standard Bunsen burner with a specified inner diameter (10mm) to provide the test flame.

Mechanism for positioning the Bunsen burner flame relative to the safety helmet or test specimen according to the standard's requirements.

Igniter timing system to control the duration for which the flame is applied to the specimen, with a wide adjustable range (0-999.9 seconds) and a typical setting (10 seconds).

Follow-on timer system to accurately measure the afterflame time (how long the specimen burns with a flame after the Bunsen burner is removed) and afterglow time (how long the specimen continues to glow without a flame), with a specified accuracy ($\pm$0.01 seconds).

Flame length measuring device with a scale (50mm length) to ensure the test flame is set to the correct size.

Capability to use specified gases (methane, propane, butane, LPG) as the fuel for the Bunsen burner, as required by the test standard.

Fixture or system to securely mount the safety helmet or a test specimen cut from the helmet for testing.

High degree of automation for the test procedure, from flame application to timing.

Safety features (implied) for conducting flame tests.
