Plastics Valves Standards
Plastics have been used in valves for many years and there have been a number of different standards created to ensure the quality and safety of these valves. The following section provides an overview of the different standards that have been established and the details of each one.
American Society of Testing and Materials (ASTM)
The American Society of Testing and Materials (ASTM) is one of the most commonly used standards for the production of plastic valves. ASTM designation F1798 covers the requirements for manufacturing a variety of plastic valves. This standard covers materials, design, and testing requirements for gate, plug, globe, and check type valves. This designation applies to valves designed for 150 PSI (1035 kPa) working pressure.
API International
API International provides a set of standards for valves made of plastic materials. This standard is designated as API 6D and covers such topics as design, materials, testing, marking, and corrosion resistance. It also covers the requirements for a variety of plastic valve styles, including gate, globe, check, ball and butterfly valves.
British Standards Institute (BSI)
The UK’s British Standards Institute (BSI) has created a set of standards for plastic valve production. The standard is designated as BS 5159 and covers topics such as materials, design, pressure rating, testing, marking, and finish requirements. This designation consists of two parts. Part 1 covers the requirements for normal duty plastic valves while Part 2 covers the requirements for extra duty plastic valves.
ISO/TS 16949
The ISO/TS 16949 is a quality management standard specifically designed for the automotive and production industries. It is a comprehensive system that covers such topics as quality planning, quality control, and continual improvement. This standard provides specific requirements for the design, testing, and production of plastic valves for automotive and production applications.
Conclusion
The range of standards for plastic valve production is quite varied and each standard offers its own requirements for design, materials, and testing. While the ASTM, API International, and BSI standards are some of the most commonly used for the production of plastic valves, there are other standards, such as the ISO/TS 16949, that address the requirements for automotive and production applications.
