1. Scope

1.1 This practice covers specific procedures and test conditions that are applicable for exposure of plastics in filtered open-flame carbon-arc devices conducted in accordance with Practices G 151 and G 152. This practice also covers the preparation of test specimens, the test condition suited for plastics, and the evaluation of test results.

1.2 This practice does not cover enclosed carbon-arc exposures of plastics, which had been allowed in Practice D 1499. Enclosed carbon-arc exposures of plastics are described in Practice D 6360, and in G 153, which gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1This practice is technically equivalent to ISO 4892-4.
