Plastics piping systems - Glass-reinforced thermosetting plastics (GRP) pipes and fittings - Test methods to prove the leaktightness of the wall under short-term internal pressure
This standard specifies two test methods, designated method A and method B, for rapid testing of the leaktightness of glass-reinforced thermosetting plastics (GRP) pipes and fittings under short-term internal pressure. Method A is a hydraulic test applicable to a pipe under uniaxial stress. Method B is a pneumatic test applicable pipes and fittings. For pipes it is intended to be complementary to method A, not an alternative test.
Kunststoff-Rohrleitungssysteme - Rohre und Formstücke aus glasfaserverstärkten duroplastischen Kunststoffen (GFK) - Prüfverfahren zur Feststellung der Dichtigkeit der Wand unter Kurzzeit-Innendruck
Diese Norm legt zwei Prüfverfahren, die als Methode A und Methode B bezeichnet werden, fest, die der schnellen Dichtigkeitsprüfung von Rohren und Formstücken aus glasfaserverstärkten duroplastischen Kunststoffen (GFK) unter Kurzzeit- Innendruck dienen. Verfahren A ist eine hydraulische Prüfung, die für ein Rohrunter einachsigem Spannungßustand anwendbar ist. Verfahren B ist eine pneumatische Prüfung, die für Rohre und Formstücke anwendbar ist. Für Rohre ist sie ergänzend zum Verfahren A vorgesehen und nicht als eine alternative Prüfung.
Systemes de canalisations en plastique - Tubes et raccords en plastique thermodurcissable renforcé de verre (PRV) - Méthode d'essai pour établir l'étanchéité de la paroi sous une pression interne a court terme
Cette norme spécifie deux méthodes d'essai désignées méthode A et méthode B, pour un essai rapide de l'étanchéité des tubes et raccords en plastique thermodurcissable renforcé de verre (PRV) sous une pression interne à court terme. La méthode A est un test hydraulique, applicable à un tube sous contrainte uniaxiale. La méthode B est un essai pneumatique applicable aux tubes et raccords. Pour les tubes, elle est prévue comme étant complémentaire à la méthode A et non pas comme essai alternatif.

General Information
Overview
EN 1229:1996 (CEN) specifies rapid test methods to assess the leaktightness of the wall of glass-reinforced thermosetting plastics (GRP) pipes and fittings when subjected to short-term internal pressure. The standard describes two complementary approaches for quick verification of integrity: Method A (hydraulic) and Method B (pneumatic). Method A applies to pipes under uniaxial stress, while Method B is applicable to both pipes and fittings and is intended to complement Method A rather than replace it.
This standard is intended for use in production testing, quality control and acceptance checks where a rapid, reproducible assessment of wall leaktightness is required.
Key Topics
- Two test methods: Method A (hydraulic) and Method B (pneumatic).
- Scope of application:
- Method A: hydraulic testing for pipes under uniaxial stress.
- Method B: pneumatic testing for pipes and fittings; complementary to Method A for pipe verification.
- Purpose: rapid proof of the wall leaktightness of GRP components under short-term internal pressure.
- Test intent: provide a fast, standardized way to detect through-wall leakage or defects in manufacturing and assembly.
- Terminology and applicability: focuses on glass-reinforced thermosetting plastics (GRP) piping systems and associated fittings.
Applications
The practical value of EN 1229:1996 includes:
- Manufacturing quality control: rapid checks on GRP pipe batches to detect defects before dispatch.
- Acceptance testing: on-site or factory acceptance of pipes and fittings prior to installation.
- R&D and failure analysis: quick screening during development or after repair to verify wall integrity.
- Regulatory and procurement compliance: supports conformity assessment by providing standardized test methods.
Benefits:
- Fast verification enables timely decision-making in production and installation workflows.
- Standardized approach reduces ambiguity between manufacturers, purchasers and testing labs.
- Complementary methods (hydraulic and pneumatic) allow flexibility depending on component type and test conditions.
Related Standards
- Other CEN standards covering plastics piping systems, GRP design, installation and performance testing provide complementary guidance.
- National adoptions and translations exist (for example, SIST EN 1229:1997 in Slovenia), reflecting harmonization across member bodies.
For implementers and test laboratories, EN 1229:1996 is a practical reference for rapid leaktightness verification of GRP pipes and fittings, helping ensure product integrity and consistent quality control without prescribing long-term performance criteria.
