ASTM E432-91(2022) - Standard Guide for selection of a leak testing method

The selection of an appropriate leak testing method is of crucial importance when measuring or locating leaks in a given system, whether in open or sealed units.

This guide, created by ASTM International (ASTM E432-91(2022) – Standard Guide for Selection of a Leak Testing Method), addresses the selection between dynamic and static test methods, each approach having its own advantages in terms of sensitivity, cost and reliability.

Dynamic test methods, although faster, generally offer lower sensitivity than static techniques. The optimum choice of leak test method therefore involves a balance between these key factors. Where several methods are available for a given system, each should be examined individually and evaluated in terms of its sensitivity to leakage. Crucially, test sensitivity is influenced by both the instrument used to measure leakage and the intrinsic characteristics of the system under test. Consequently, the choice of instrument and test method also depends on environmental conditions such as temperature, pressure and the nature of the fluids involved.

By choosing the right test method from the outset, you save time and money by avoiding the costly errors associated with inadequate leak detection. Every system is unique. Our approach is to offer you tailor-made solutions, taking into account the specifics of your working environment and the fluids involved.

This guide, created by ASTM International (ASTM E432-91(2022) – Standard Guide for Selection of a Leak Testing Method), provides an essential framework for the effective selection of a leak testing method adapted to each situation, taking into account the specific requirements of sensitivity, cost and reliability of the system to be tested.
