Plastics piping and ducting systems — Determination of the long-term hydrostatic strength of thermoplastics materials in pipe form by extrapolation

Plastics piping and ducting systems — Determination of the long-term hydrostatic strength of thermoplastics materials in pipe form by extrapolation

ISO 9080:2012 specifies a method for predicting the long-term hydrostatic strength of thermoplastics materials by statistical extrapolation. The method is applicable to all types of thermoplastics pipe at applicable temperatures. It was developed on the basis of test data from pipe systems.

Systèmes de canalisations et de gaines en matières plastiques — Détermination de la résistance hydrostatique à long terme des matières thermoplastiques sous forme de tubes par extrapolation

L'ISO 9080:2012 décrit une méthode d'estimation de la résistance hydrostatique à long terme des matières thermoplastiques à l'aide d'une extrapolation par les statistiques. La méthode peut être utilisée pour tous les types de tubes thermoplastiques aux températures appropriées. Elle a été développée sur la base de données d'essai provenant de systèmes de canalisations.

Thermoplastics pipes — Longitudinal reversion — Test method and parameters

This document specifies a method for determining the longitudinal reversion of thermoplastics pipes, to be carried out in either a liquid or in air. In case of dispute, heated liquid is used as the reference. This document is applicable to all thermoplastics pipes with smooth internal and external walls of constant cross‑section. It is not applicable to non‑smooth structured‑wall thermoplastics pipes. The parameters appropriate to the pipe material and recommendations for the maximum levels of reversion as a function of the pipe material are given in Annex A. This method is applicable for pipes of wall thickness ≤ 16 mm.

Thermoplastics pipes for the transport of fluids — Determination of Charpy impact properties — Part 1: General test method

This document specifies two general test methods, Method A and Method B, to be used for the determination of the impact properties of unnotched and notched specimens cut from thermoplastics pipes for the transport of fluids. — Method A: unnotched method, for unnotched specimens cut from thermoplastics pipes for the transport of fluids. — Method B: notched method, for specimens cut from thermoplastics pipes for the transport of fluids, into which a notch has been machined. The use of Method A or Method B is determined by the relevant product standards. This document is not intended as a reference test method for the determination of the impact strength of pipes. ISO 3127, relating to the determination of the impact strength of pipes by means of a falling mass, is the reference test method. However, this document can be used for scientific research, materials testing or the examination of pipe when it is not possible to take measurements in accordance with the reference method. This document can be applied to either isolated batches or continuous production of pipe.

Thermoplastic pipes for the conveyance of fluids — Inspection of polyethylene electrofusion socket joints using phased array ultrasonic testing

This document describes the phased array ultrasonic testing (PAUT) of polyethylene electrofusion (EF) socket joints used for the conveyance of fluids. This document provides a test whereby the presence of imperfections such as voids, wire dislocation, misalignment, pipe under-penetration, particulate contamination, cold fusion and lack of fusion in electrofusion socket joints can be detected. The technique is only applicable to polyethylene electrofusion socket fittings without a barrier to ultrasonic waves. This document also provides requirements for procedure qualification and guidance for personnel qualifications, which are essential for the application of this test method NOTE 1 At the time of publication, experience only exists on the use of PAUT for polyethylene (PE80 and PE100) electrofusion socket joint sizes between 90 mm and 710 mm (SDR 11 and 17)[7][8][9][10][11][12][13]. NOTE 2 Round robin testing has shown that PAUT is a viable method for enhancing the integrity assessment of electrofusion joints[16]. NOTE 3 This document does not apply to the detection of unscraped pipe. Such detection can be achieved by a simple visual inspection, provided mechanical scraping tools are employed.

Thermoplastic pipes for the conveyance of fluids — Inspection of polyethylene butt fusion joints using phased array ultrasonic testing

This document describes the phased array ultrasonic testing (PAUT) of polyethylene butt fusion (BF) joints, including pipe-to-pipe, pipe-to-fitting and fitting-to-fitting joints, used for the conveyance of fluids. This document provides a test, whereby the presence of imperfections such as voids, inclusions, lack of fusions, misalignment and particulate contamination in the BF joints can be detected. The document is only applicable to polyethylene pipes and fittings without a barrier to ultrasonic waves. This document also provides requirements for procedure qualification and guidance for personnel qualifications, which are essential for the application of this test method. This document also covers the equipment, the preparation and performance of the test, the indication assessment and the reporting for polyethylene BF joints. The assessment of ultrasonic indications and acceptance criteria are not covered in this document. NOTE 1 At the present time, laboratory experiences exist on the use of PAUT for polyethylene BF joints and/or reference blocks of wall thickness between 8 mm to 100 mm[1] to [5]. Recently, field experience on BF joints in PE80 and PE100 materials has been reported[6]. NOTE 2 Round robin testing has shown that PAUT is a viable method for enhancing the integrity assessment of BF joints[7]. NOTE 3 PAUT techniques for cold fusion detection are known to be available. However further research, verification and experience are needed to transfer the technique into an ISO Standard. This document does not provide any information regarding the detection of cold fusions.
