GB/T 1634.1-2025 Plastics—Determination of temperature of deflection under load—Part 1:General test method
Abstract
This document describes a general method for determining the deformation temperature of plastic loads (bending stress under three-point loading) and evaluating the relative performance of different types of plastic materials when they are heated to high temperatures at a specified heating rate under a specified load.
This document specifies the preferred dimensions of the samples.
