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.

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.

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.

Overview
SIST EN 1229:1997 sets out test methods to assess the leaktightness of the walls of glass-reinforced thermosetting plastics (GRP) pipes and fittings under short-term internal pressure. This Slovenian standard, aligned with EN 1229:1996, is essential for manufacturers, testing laboratories, and quality assurance teams involved with GRP piping systems. It specifies two rapid test procedures - a hydraulic test (method A) and a pneumatic test (method B) - to ensure the structural integrity and safety of GRP pipes and fittings under prescribed conditions.
Key Topics
Test Methods:
- Method A (Hydraulic Test): Utilizes liquid under pressure to evaluate the leaktightness of GRP pipes subjected to uniaxial stress. Primarily applied to pipes, this rapid method simulates real-world operating conditions and is fundamental for routine quality checks.
- Method B (Pneumatic Test): Employs gas under pressure for testing both GRP pipes and fittings. While this method is applicable to a broader range of components, it is intended to complement, not replace, the hydraulic test on pipes.
Leaktightness Verification: Provides a systematic approach for detecting wall defects and ensuring that GRP piping components maintain pressure without leaks over a short-term duration.
Testing Scope: The relevance of the two methods is outlined - specifying where hydraulic or pneumatic approaches should be used and that, for pipes, pneumatic tests are not substitutes for hydraulic testing, but rather additional safeguards.
Applications
SIST EN 1229:1997 is widely referenced in the manufacturing, construction, and maintenance of plastics piping systems using GRP materials (glass-reinforced plastics). Typical applications include:
- Water Distribution: GRP pipes are favored for water supply networks due to their corrosion resistance and durability. Reliable leaktightness is critical to prevent loss and contamination.
- Industrial Piping: Many chemical and industrial facilities use GRP pipes to transport liquids under pressure. Rapid and accurate leaktightness testing prevents costly failures and safety incidents.
- Sewage and Drainage Systems: GRP pipes and fittings are increasingly used in waste management infrastructure, necessitating robust testing for leakage under operational pressures.
With the methods described in this standard, manufacturers can perform efficient short-term internal pressure tests, thereby maintaining product quality and complying with international specifications in plastics piping systems.
Related Standards
Organizations and industry professionals working with GRP pipes and fittings should also be familiar with the following related standards:
- EN 1796: Plastics piping systems for water supply with glass-reinforced thermosetting plastics (GRP)
- EN 14364: Plastics piping systems for drainage and sewerage under pressure - GRP
- ISO 10467: Plastics piping systems for pressure and non-pressure drainage and sewerage - Glass-reinforced thermosetting plastics
- SIST EN 10204: Metallic products - Types of inspection documents (for reference in quality control and testing documentation)
By adhering to SIST EN 1229:1997, stakeholders can ensure the leaktightness and reliability of GRP pipelines, supporting safety and regulatory compliance throughout the systems’ operational life.
