Overview
EN ISO 10931:2005/A1:2015 specifies the requirements for plastics piping systems used in industrial applications, focusing on systems made from poly(vinylidene fluoride) (PVDF). This international standard, developed by CEN and ISO, outlines specifications for both system components and overall system performance. PVDF is widely recognized for its excellent chemical resistance and durability, making it suitable for demanding industrial environments.
Key Topics
This standard encompasses several essential elements related to plastic piping systems made of PVDF:
- Component Specifications: Defines the properties, dimensions, and tolerances for PVDF piping components such as pipes, fittings, and joints.
- System Requirements: Details performance criteria for the complete piping system in industrial settings.
- Wall Thickness Tolerances: Provides updated tables and values for nominal wall thicknesses and their related tolerances, ensuring safety and reliability.
- Material Suitability: Covers the use of PVDF due to its high resistance to a wide range of chemicals and its mechanical strength.
- International Harmonization: Aligns requirements across ISO and CEN member countries, supporting global adoption and compliance.
Applications
EN ISO 10931:2005/A1:2015 is particularly relevant for industries seeking reliable piping solutions that must perform under harsh conditions. Common applications include:
- Chemical Processing: Due to the chemical resistance of PVDF, these piping systems are ideal for transporting aggressive fluids and gases.
- Water Treatment: Used in treatment plants for conveying corrosive or purified water where contamination and corrosion prevention are critical.
- Semiconductor Manufacturing: PVDF piping is chosen for carrying ultra-pure water and chemicals required during semiconductor fabrication.
- Industrial Waste Handling: Facilitates safe transport of hazardous and corrosive waste materials within industrial complexes.
- Pharmaceutical and Food Industries: Ensures hygienic fluid transport in environments requiring high purity and certified material performance.
