ASTM D5025 Standard Specification for Laboratory Burner Used for Small-Scale Burning Tests on Plastic Materials
ASTM D5025 塑料材料的小型燃烧试验用实验室燃烧器的标准规范

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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. 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.

Note 1—The burner described in this specification is suitable for use in the following ASTM standards: Specification C 509, Test Method D 229, Test Method D 635, Test Method D 876, Test Method D 3014, Test Method D 3801, Test Method D 4804, Test Method D 4986, and Test Method D 5048. Safety hazards and known limitations on applicability of fire-test-response standards are addressed in the individual test methods.

Note 2—This specification is equivalent to the ignition source specified in IEC 60695-11-3, Annex A and IEC 60695-11-4, Annex A.
Note 3—This specification is equivalent to the P/PF2 ignition source specified in ISO 10093.
