Rationale

The August ballot for this standards’ 5-year review yielded a negative vote with comments which were discussed at the subcommittee meeting in November 2025. As a result, several revisions were proposed and agreed upon at the meeting which include. - Changes to void criteria in Table 1 to reduce acceptable size and occurrence of voids. - Inclusion of a dimensional tolerance for test specimen sizes - Update existing environmental conditions to align with D618 standard practice for conditioning plastics for testing and addition of standard environmental conditions to the screw pullout test. - Clarification to storage responsibility requirements to avoid duplicated screw pullout testing by specifying 10.2.2 physical requirements for foam that previously met 10.2 acceptance criteria for both suppliers and users. - Removal of last sentence in X1.2 because it is not relevant to rationale. - Addition of X1.8 to provide background on dimensional stability test method.
