Full title and description

STB DIN EN ISO 19893 E 2017-06 — Plastics piping systems: Thermoplastics pipes and fittings for hot and cold water — Test method for the resistance of mounted assemblies to temperature cycling. This is an English-language national/adopted publication corresponding to the ISO 19893 test method for evaluating how mounted pipe assemblies withstand repeated temperature changes.

Abstract

This document specifies a laboratory test method to determine the resistance of joints and mounted assemblies for thermoplastic piping systems to temperature cycling (thermal shock). It applies to assemblies intended for pressure applications with hot and cold water and is used to assess joint performance and durability under repeated temperature changes.

General information

• Status: Adopted national edition (STB listing) of the DIN/EN/ISO publication; national adoptions of the ISO text have appeared in several countries (note: some national editions have been marked withdrawn or superseded in local catalogs while the underlying ISO 19893:2011 remains an active confirmed International Standard).
• Publication date: Designation shows 2017-06 (DIN EN ISO adoption dated 01 June 2017); the original ISO standard was published December 2011 (ISO 19893:2011).
• Publisher: Original publisher: International Organization for Standardization (ISO). National/adopted editions published/distributed by national bodies or authorized resellers (DIN / national standards body; STB listing for the titled document).
• ICS / categories: 23.040.20 Plastics piping systems; 23.040.45 Plastics pipes and fittings (as recorded on the ISO bibliographic entry).
• Edition / version: Adopted edition labelled 2017-06 (corresponding to ISO 19893:2011, Edition 1).
• Number of pages: Varies by publication: original ISO text is 8 pages; the DIN/EN/STB national publication listings show larger page counts for their formatted national documents (example: DIN listing shows 26 pages, other national EN adoptions 14 pages).

Scope

The standard specifies a test method for assessing the resistance of mounted pipe assemblies (joints, fittings and associated mounted configurations) made from thermoplastics when exposed to repeated temperature cycling representative of hot and cold water service conditions. It is intended for thermoplastic piping systems used in pressure water applications (hot and cold potable and service water).

Key topics and requirements

• Definition of test specimens (mounted assemblies and joints) and preparation requirements.
• Specified temperature cycling procedure to simulate thermal shock / repeated hot–cold exposure.
• Performance assessment criteria for leaks, deformation and mechanical integrity after cycling.
• Applicability to rigid and flexible thermoplastic pipe systems for hot and cold water pressure applications.
• Guidance on reporting test conditions and results to support conformity assessment and product comparison.

Typical use and users

Used by manufacturers of thermoplastic pipes, fittings and jointing systems, independent test laboratories, certification and approval bodies, product designers and specifiers, and regulatory authorities concerned with plumbing and water-supply system performance. The test supports product development, quality control and compliance demonstration for systems intended for hot and cold water service.

Related standards

ISO 19893 is part of the plastics piping technical area overseen by ISO/TC 138. It is related to other ISO and EN/ISO series on plastics piping for hot and cold water, for example the EN/ISO 15875 series (plastics piping systems for hot and cold water installations — PE‑X) and other part-specific test and fitness-for-purpose standards for pipes, fittings and joints. National EN adoptions (DIN EN ISO, BS EN ISO, ÖNORM EN ISO, etc.) mirror the ISO content and may include national forewords or formatting.

FAQ

Q: What is this standard?

A: It is the ISO test-method standard (ISO 19893) for evaluating the resistance of mounted thermoplastic pipe assemblies and joints to temperature cycling; the document titled "STB DIN EN ISO 19893 E 2017-06" refers to a national/adopted edition of the DIN/EN/ISO text in English with a 2017 adoption date.

Q: What does it cover?

A: The test procedure for subjecting mounted assemblies to repeated hot and cold cycles and the criteria for assessing their integrity (leakage, deformation, mechanical failure) in pressure water applications. It applies to rigid and flexible thermoplastic pipe systems used for hot and cold water.

Q: Who typically uses it?

A: Manufacturers, independent testing laboratories, conformity-assessment and certification bodies, product designers and specifiers, and authorities overseeing plumbing and water-supply system safety and reliability.

Q: Is it current or superseded?

A: The underlying ISO 19893:2011 text is an active International Standard (ISO bibliographic entry shows publication in December 2011 and confirmation on review). Some national listings show adoption with later publication dates (e.g., DIN EN ISO adoption dated 01 June 2017) and in certain national catalogs that adoption entry is marked withdrawn or superseded; check the relevant national standards body or the ISO store for the authoritative current status in your country.

Q: Is it part of a series?

A: It sits within the plastics piping systems group of standards (ISO/TC 138) and complements part-specific series such as the ISO/EN ISO 15875 family and other test/fitness-for-purpose standards for pipes, fittings and joints used in hot and cold water installations.

Q: What are the key keywords?

A: Thermoplastics, piping systems, temperature cycling, thermal shock, joints, fittings, hot water, cold water, test method, ISO 19893.
