ASTM D1042-26 Standard Test Method for Linear Dimensional Changes of Plastics Caused by Exposure to Heat and Moisture

This test method is designed to provide a means for measuring the dimensional changes of plastic specimens such as shrinkage or expansion, developed under specific heat and water conditionings.

This test method is intended only as a convenient test method for measurement of linear dimensional changes in plastics subjected to defined conditions of test as outlined in Sections 7 and 8.
