Appendix 3 - Test methods and criteria for flame spread, smoke
generation and toxicity of plastic piping
Flame spread, smoke generation and toxicity of plastic piping should be
determined by the 2010 FTP Code, annex 1, parts 2 and 5 with the modifications listed below.
Tests should be made for each pipe material and should take into account
differences in wall thickness.
When conducting testing of plastic piping, testing need not be conducted
on every pipe size. Testing should be conducted on pipe sizes with the maximum and
minimum wall thicknesses intended to be used. This will qualify all piping sizes for
a specific piping material provided that the wall thickness falls within the tested
range.
1 Test Specimen Preparation
1.1 For homogenous thermoplastic pipes, the test specimens may
be produced as flat plates in the required wall thickness(es).
1.2 The test sample should be fabricated by cutting pipes
lengthwise into individual sections and then assembling the sections into a test
sample as representative as possible of a flat surface. A test sample should consist
of at least two sections. All cuts should be made normal to the pipe wall. The test
sample should be 800 mm ± 5 mm long for tests to 2010 FTP Code, annex 1, part 5. The test sample should be 75 mm ± 1 mm square for
tests to 2010 FTP Code, annex 1, part 2.
1.3 The number of sections that must be assembled together to
form a test sample should be that which corresponds to the nearest integral number
of sections which should make a test sample (with an equivalent linearized surface
width between 155 mm and 180 mm). The surface width is defined as the measured sum
of the outer circumference of the assembled pipe sections that are exposed to the
flux from the radiant panel.
1.4 The assembled test sample should have no gaps between
individual sections.
1.5 The assembled test sample should be constructed in such a
way that the edges of two adjacent sections should coincide with the centreline of
the test holder.
1.6 For testing flame spread the individual test sections
should be attached to the backing calcium silicate board using wire (No.18
recommended) inserted at 50 mm intervals through the board and tightened by twisting
at the back.
1.7 The individual pipe sections should be mounted so that the
highest point of the exposed surface is in the same plane as the exposed flat
surface of a normal surface.
1.8 The space between the concave unexposed surface of the test
sample and the surface of the calcium silicate backing board should be left void.
1.9 The void space between the top of the exposed test surface
and the bottom edge of the sample holder frame should be filled with a high
temperature insulating wool if the width of the pipe segments extend under the side
edges of the sample holding frame.
2 Test Methods
Flame spread of plastic piping should be determined by the 2010 FTP Code,
annex 1, part 5. The smoke density and toxicity of gases
produced by plastic pipes should be determined by the 2010 FTP Code, annex 1, part 2.
