Overview
SIST EN ISO 13056:2018 is an international standard developed by CEN that specifies a test method for verifying the leaktightness of joints in thermoplastics piping systems under vacuum conditions. This standard is specifically designed for pressure piping systems intended for hot and cold water applications. By providing a systematic procedure to evaluate the airtightness of pipe joints, SIST EN ISO 13056:2018 ensures the reliability and safety of thermoplastics piping systems used in water supply and related infrastructure.
Key Topics
-
Scope
Focuses on thermoplastics piping systems used for transporting hot and cold water under pressure. Applies to joints in these piping systems, ensuring they remain leak-tight under vacuum conditions.
-
Test Methodology
The test involves subjecting a pipe assembly with joints to a controlled partial vacuum over a specific duration. During the test, any pressure change indicating leakage is monitored to assess joint integrity.
-
Test Parameters
Critical parameters such as number of test pieces, test temperature, vacuum pressure level, test duration, and failure thresholds for pressure increase are defined by the referring standard that references EN ISO 13056.
-
Apparatus and Setup
The standard details required equipment: vacuum pumps, precise vacuum pressure gauges (with ±0.01 bar accuracy), shut-off valves, temperature measurement devices, and end-sealing components designed to isolate the test piece without stressing the joints.
-
Test Procedure
Pipes and fittings are assembled per manufacturer’s instructions and conditioned at a controlled temperature (typically 23 ± 5 °C). The vacuum is applied to the assembly, isolated at the correct pressure, and the system is monitored for any pressure increase indicating leaks.
-
Reporting
A comprehensive test report is mandatory, covering reference standards, component specifications, test temperatures and duration, applied pressures, measured pressure changes, and any anomalies during testing.
Applications
-
Plastics Piping Systems for Water Supply
SIST EN ISO 13056:2018 ensures the long-term durability and safety of thermoplastics piping used in residential, commercial, and industrial water supply systems where hot and cold water pressures must be managed without leakage.
-
Quality Assurance in Manufacturing and Installation
Manufacturers use this standard to verify product quality and joint performance. Installation contractors benefit from clear test procedures to validate pipe system integrity post-installation.
-
Infrastructure and Building Safety Compliance
The standard supports compliance with regulatory requirements for pressure piping systems, contributing to risk mitigation in plumbing systems, heating installations, and water distribution networks.
-
Research and Development
Enables efficient testing during the development phase of new thermoplastics piping materials and joint designs, ensuring compatibility with vacuum conditions common in pressure system leak testing.
Related Standards
