Standard Specification for Laboratory Burner Used for Small-Scale Burning Tests on Plastic Materials
ABSTRACT
This specification covers the physical dimensions and characteristics of a laboratory burner used for small-scale burning tests on plastic materials, with the supply gases including methane, propane, and butane. The burner shall consist of a burner barrel that threads onto a one-piece base, which is equipped with an orifice and a needle valve that restricts the orifice opening and regulates the gas velocity through the burner, and a gas inlet, which consists of a serrated fitting for connection to the gas supply. A lock nut for securing the barrel onto the base may be provided optionally. The mixing tube of the barrel shall be manufactured with a uniform bore, and the barrel, threads, and serrated fitting shall be free of flash and burrs.
SCOPE
1.1 This specification covers the physical dimensions and characteristics of a laboratory burner to be used as an ignition source for small-scale burning tests on plastic materials. The burner is used with methane, propane, or butane supply gases for flame heights of 20 to 125 mm.
1.2 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests.
1.3 The burner described in this specification is suitable for use in the following ASTM standards: Specification C509, Test Method D229, Test Method D635, Test Method D876, Test Method D3014, Test Method D3801, Test Method D4804, Test Method D4986, and Test Method D5048. Safety hazards and known limitations on applicability of fire-test-response standards are addressed in the individual test methods.
Note 1: This specification is equivalent to the ignition source specified in IEC 60695-11-3, Annex A and IEC 60695-11-4, Annex A.
Note 2: This specification is equivalent to the P/PF2 ignition source specified in ISO 10093.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
