ASTM E 2231 : 2018 : REDLINE

1.1This practice describes procedures for specimen preparation and mounting when testing pipe and duct insulation materials to assess flame spread and smoke development as surface burning characteristics using Test Method E84.

1.2If the pipe or duct insulation materials to be tested are reflective insulation materials (see 3.2.10 and 3.2.11), the materials shall be tested using the procedures for specimen preparation and mounting described in Practice E2599 and not the procedures described in 6.1 through 6.6.

1.3Testing is conducted with Test Method E84.

1.4This practice does not provide pass/fail criteria that can be used as a regulatory tool.

1.5Use the values stated in inch-pound units as the standard, in referee decisions. The values in the SI system of units are given in parentheses, for information only; see IEEE/ASTM SI-10 for further details.

1.6This fire standard cannot be used to provide quantitative measures.

1.7Fire 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 8.

1.8The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the standard.

1.9This 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.

1.10This fire standard cannot be used to provide quantitative measures.

1.11This 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.
