Glass-reinforced thermosetting plastics (GRP) pipes. Determination of initial ring stiffnessWhat is ISO 7685 Glass reinforced thermosetting plastics (GRP) pipes about? ISO 7685 discusses glass reinforced thermosetting plastics (GRP) pipes. ISO 7685 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. Who is ISO 7685
