Help needed regarding flame projection
Thread Content
Recently, the company’s products are to be tested for filling into aerosol cans. Since they are solvent-based cleaners that are flammable, a customer referred to MIL-PRF-29608B and mentioned a test criterion called \"flame projection.\" What exactly is this criterion? Is it simply the literal translation of \"flame spread distance\"? Are there any relevant standards and testing methods in China?
Ask yourself and answer it: relevant standards have been identified recently, and members who need them can refer to them. In GB/T14449-1993, the testing method for the flammability of aerosol products, specifically item b, uses the method of measuring the flame spread length; this method is the same as that specified in U.S. military standards. In contrast, GB/T14449-2008 changes the testing method for the flammability of aerosol mist to one that measures the ignition distance, as well as tests for the flammability in enclosed spaces and the flammability of foam

It is the flame stiffness. This data needs to be tested on a specialized torch testing apparatus to generate a test report.
