Abstract
Overview
EN ISO 9969:2016 - Thermoplastics pipes: Determination of ring stiffness () specifies a laboratory test method for determining the of circular-section thermoplastic pipes. Adopted by CEN as a European Standard, this third edition supersedes EN and defines the apparatus, test pieces, conditioning, test procedure and calculation required to report ring stiffness values for quality control, type testing and specification compliance.
