The Brazilian Association of Technical Standards (ABNT) has recently published significant updates to standards governing plastic piping systems, emphasizing their importance in water supply, drainage, and sewage applications. These standards, developed by the Basic Sanitation Technical Committee (ABNT/CB-177), contribute to the advancement of technologies ensuring the reliability and safety of plastic piping systems.
ABNT NBR 15593:2022 Amendment 1:2023 – Polyethylene (PE) Weldable Connections for Plastic Piping Systems
Published on 20/12/2023, the ABNT NBR 15593:2022 Amendment 1:2023 focuses on polyethylene (PE) weldable connections for plastic piping systems used in water supply, drainage, and pressurized sewage. Developed by the Basic Sanitation Technical Committee, this standard specifies connections made from PE 80 or PE 100 for both underground and above-ground applications. These connections are intended for the transportation of potable water, raw water before treatment, drainage, pressurized sewage, vacuum sewer systems, and water for other purposes.
ABNT NBR ISO 13968:2023 – Thermoplastic Pipes – Determination of Ring Flexibility
Released on 18/12/2023, the ABNT NBR ISO 13968:2023 focuses on the flexibility of thermoplastic pipes, presenting a method for determining the ring flexibility of circular cross-section pipes. The standard plays a crucial role in assessing the performance and durability of thermoplastic pipes within various applications.
ABNT NBR ISO 9969:2023 – Thermoplastic Pipes – Determination of Ring Stiffness
Published on 15/12/2023, the ABNT NBR ISO 9969:2023 outlines a method for determining the ring stiffness of thermoplastic pipes with circular cross-sections. This standard provides a comprehensive testing approach, allowing for the accurate evaluation of the structural integrity and stability of thermoplastic pipes.
