(Practice)Standard Practice for Evaluating the Quality of Molded Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings by the Heat Reversion Technique
Standard Practice for Evaluating the Quality of Molded Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings by the Heat Reversion Technique
SIGNIFICANCE AND USE
3.1 This practice 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 2),
3.1.2 Determine the amount of molded-in stress produced by the molding process (Note 3),
3.1.3 Reveal contamination, and
3.1.4 Show the quality of the weld line.
Note 2: A cold slug is a piece of material that enters the mold at a significantly lower temperature than the rest of the mass.
Note 3: 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.
SCOPE
1.1 This practice covers a procedure for evaluating the quality of molded poly(vinyl chloride) (PVC) plastic pipe fittings after exposure to heat.
1.2 Units—The values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
Note 1: The values in square brackets are SI units requirements.
1.3 This 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 and health practices and determine the applicability of regulatory limitations prior to use.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Plastic Pipe Fittings by the Heat Reversion Technique
This standard is issued under the fixed designation F610/F610M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
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 SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
1.3 This 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 and health practices and determine the applicability of regulatory
limitations prior to use.
2. Summary of Test Method
2.1 A representative sample of the fitting being produced is placed in a thermostatically controlled oven at 302 6 5.4°F [150
6 3°C] for 30 min. The acceptability of the fitting quality, after the required test time, is based or expressed as a percentage of
the original wall thickness or surface area of the fitting.
3. Significance and Use
3.1 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.
4. Apparatus
4.1 Circulating Air Oven, thermostatically controlled, capable of operating at 302 6 5.4°F [150 6 3°C] such that after insertion
of the fittings to be tested the test temperature is regained within 15 min or less. (See Annex A1.)
NOTE 3—The oven should be vented to the outside of the building.
5. Conditioning
5.1 A specific conditioning period is not required although the fitting shall be at room temperature. This test can be performed
on a particular fitting any time after it has been produced.
6. Procedure
6.1 Select the fittings to be tested and examine them for the following, making proper notation for the report:
