ASTM F610/F610M-00a(2005)

This test method is applicable to distinguish between properly and improperly molded PVC plastic pipe fittings. It can be used to:

3.1.1 Determine whether cold slugs or unfused areas are present (Note 1),

3.1.2 Determine the amount of molded-in stress produced by the molding process (Note 2),

3.1.3 Reveal contamination, and

3.1.4 Show the quality of the weld line.

Note 1—A cold slug is a piece of material that enters the mold at a significantly lower temperature than the rest of the mass.

Note 2—A stress-free part will generally have better properties and higher strength than those with a high degree of stress. Stress-free parts will generally react better when exposed to chemicals.

1.1 This test method covers a procedure for evaluating the quality of molded poly(vinyl chloride) (PVC) plastic pipe fittings after exposure to heat.

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.3 This standard does not purport to address all of the safety problems, 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.
