1 Scope This standard specifies test methods for size measurement , hardness, tensile property, hot air aging, constant deformation compression set, corrosion and liquid resistance, density, shrinkage , low temperature test and compression relaxation of solid vulcanized rubber O-ring. This standard is applicable to solid vulcanized rubber O-ring (hereinafter referred to as O-ring). 2 Normative References The following documents contain provisions which, through reference in this standard, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply. However, the parties who enter into agreement according to this part are encouraged to research whether the latest editions of these documents may be applied. For undated references, the latest edition referred to apply.
