    1 Scope

    1.1 This is a test method for determining values of flame propagation distance and optical smoke density for individual pairs of plastic plumbing pipes for distribution of potable water, water used for hydronic heating and cooling applications, water reclaim/reuse water applications.

    1.2 This test method addresses uninsulated pipe sizes 4 in. (10.2 cm) and less in diameter. This test method also addresses insulated pipe assemblies which, based on the end use, can include thermal insulation. The overall sizes of these pipe assemblies are to be 5 inches (12.7 cm) and less in diameter.

    1.3 This test method does not cover plastic pipes when installed adjacent (side to side) in quantities greater than two.

    1.4 This test method does not cover the construction requirements for plastic plumbing pipe for pressure or other performance requirements
