GB/T 22472 - 2008 focuses on measuring the combustion properties of plastics used in instruments and equipment components. It elaborates on a variety of combustion properties measurement methods and principles, specifies the type of test equipment, performance indicators, etc., standardizes the selection, preparation and state adjustment of plastic samples, and clarifies various test procedures, such as different ignition times, observation indicators and combustion grade judgment rules. The standard provides unified specifications for the instrumentation and equipment production industry, helps to accurately evaluate the combustion characteristics of plastics used in components, ensures the fire safety of products in the operation of electrical, mechanical and other equipment, and promotes the mass improvement of related plastic products.
