What is ISO 9969 - Ring stiffness of thermoplastics pipes about?
Thermoplastics pipes are lightweight and durable which makes them popular.
ISO 9969 specifies a test method for determining the ring stiffness of thermoplastics pipes having a circular cross-section.
Who is ISO 9969 - Ring stiffness of thermoplastics pipes for?
ISO 9969 on ring stiffness of thermoplastics pipes is useful for companies associated with:
- Water distribution
- Drainage and sewage system
- Waste management
- Irrigation
- Conduit
- Fire sprinkler
- Process piping
- Gas distribution
Why should you use ISO 9969 - Ring stiffness of thermoplastics pipes?
Thermoplastics are plastic polymers used as alternatives to traditional pipelining materials. They are used in handling slurries like bottom ash, fly ash, and different types of abrasive solutions. Thermoplastics pipes offer high-pressure capacity, reliability, ruggedness, corrosion resistance, and are easy to install.
ISO 9969 walks you through the process to determine the ring stiffness of thermoplastics pipes. ISO 9969 provides guidance on:
- Symbols
- Dimensional measuring devices,
- Force measuring device
- Marking and number of test pieces
- Length of test pieces
- Age of test pieces
- Examples of the pipe wall construction height,
- Method of correcting origin
The guidelines in ISO 9969 help you to run the test for evaluating the ring stiffness of thermoplastics pipes to determine their resistance to vertical deformation, so that end customers can use superior quality products.
