ASTM-E2690 › Standard Practice for Specimen Preparation and Mounting of Caulks and Sealants to Assess Surface Burning Characteristics
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This practice describes procedures for specimen preparation and mounting when testing caulks and sealants up to 8 in. (203.2 mm) in width to assess flame spread and smoke development as surface burning characteristics using Test Method E84. Caulks and sealants in excess of 8 in. (203.2 mm) are to be tested in full coverage as applied to fiber cement board as described in Test Method E84.
1.2 This practice applies to caulks and sealants intended for various uses within buildings. The caulks and sealants addressed in this practice are not able to be supported by their own structural characteristics during the test.
1.3 Testing is conducted in accordance with Test Method E84.
1.4 This practice does not provide pass/fail criteria that can be used as a regulatory tool.
1.5 This practice does not apply to materials for which the test specimen does not remain in place before and during the test until maximum flame propagation has occurred.
1.6 This practice is not for system evaluation. It is for the comparison of the materials only.
1.7 The results obtained by using this mounting procedure are confined to the materials themselves as tested and are not comparable to materials that are tested in a full tunnel width application.
1.8 This fire standard cannot be used to provide quantitative measures.
1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.10 This standard gives instructions on specimen preparation and mounting, but the fire-test-response method is given in Test Method E84. See also Section 9.
1.11 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.
1.12 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.
1.13 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.
