Methods of test for plastic pipes and fittings, Method 29: Plastics piping and ducting systems - Determination of the long-term hydrostatic strength of thermoplastics materials in pipe form by extrapolation
塑料管道和配件的试验方法 方法29:塑料管道和管道系统.用外推法测定管形热塑性材料的长期静水压强度
The objective of this Test Method is to specify a method for predicting the long-term hydrostatic strength of thermoplastics materials by statistical extrapolation. The method is applicable to all types of thermoplastics pipe at applicable temperatures. This Test Method was developed on the basis of test data from pipe systems.
