【国外标准】 Standard Practice for Specimen Preparation and Mounting of Site-Fabricated Stretch Systems to Assess Surface Burning Characteristics

5.1 Site-fabricated stretch systems used as interior finish are evaluated with Test Method E84 to comply with building, fire, or life safety code requirements. This practice describes specimen preparation and mounting procedures for such materials and systems.5.2 The limitations for this procedure are those associated with Test Method E84.5.3 Additional Limitations—This practice does not apply to test systems that cannot be used to produce self-supporting specimens. If the test specimen is not self-supporting, further guidance can be found in Annex A4 of Test Method E84.5.4 This practice shall not apply to vinyl stretch ceiling materials, which are covered by Practice E2599.1.1 This practice describes procedures for specimen preparation and mounting when testing a site-fabricated stretch system to assess flame spread and smoke developed as surface-burning characteristics using Test Method E84.1.2 Testing is conducted with Test Method E84.1.3 This practice does not provide pass/fail criteria that can be used as a regulatory tool.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. See IEEE/ASTM SI-10 for further details.1.5 This fire standard cannot be used to provide quantitative measures.1.6 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. Fire testing involves hazardous materials, operations, and equipment. This standard gives instructions on specimen preparation and mounting, but the fire-test-response method is given in Test Method E84. See also Section 10.1.7 This practice shall not apply to vinyl stretch ceiling materials, which are covered by Practice E2599.1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes shall not be considered requirements of the standard.1.10 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.
