3、d in April 2011.1.Scope1.1 This practice describes procedures for specimen prepa-ration and mounting when testing caulks and sealants intendedto be applied up to 8 in.(203.2 mm)in width to assess flamespread and smoke development as surface burning character-istics using Test Method E84.Caulks and s
4、ealants intended tobe applied in excess of 8 in.(203.2 mm)are to be tested appliedto a substrate so as to completely cover the substrate in a fulltunnel width application of Test Method E84.1.2 This practice applies to caulks and sealants intended forvarious uses within buildings.The caulks and seal
5、ants ad-dressed in this practice are not able to be supported by theirown structural characteristics during the test unless they areapplied to a substrate.1.3 Testing is conducted in accordance with Test MethodE84.1.4 This practice does not provide pass/fail criteria that canbe used as a regulatory
6、tool.1.5 This practice does not apply to materials for which thetest specimen does not remain in place before and during thetest until maximum flame propagation has occurred.1.6 This practice is not for system evaluation.It is for thecomparison of the materials only.1.7 The results obtained by using
7、 this mounting procedureare confined to the materials themselves as tested and are notcomparable to those obtained with materials that are tested ina full tunnel width application.1.8 This fire standard cannot be used to provide quantitativemeasures.1.9 Fire testing is inherently hazardous.Adequate
8、safe-guards for personnel and property shall be employed inconducting these tests.1.10 This standard gives instructions on specimen prepara-tion and mounting,but the fire-test-response method is given inTest Method E84.See also Section 9.1.11 The text of this standard references notes and footnotesw
