ISO 7685:2019 Glass-reinforced thermosetting plastics (GRP) pipes - Determination of initial ring stiffness
standard by International Organization for Standardization, 07/01/2019
Full Description
ISO 7685:2019 specifies methods for determining the initial ring stiffness of glass-reinforced thermosetting plastics (GRP) pipes. Two methods are given (constant load and constant deflection), and within the specified deflection limits, each is equally valid and can be used for any diameter.
