What is ISO 9967 - Creep ratio of thermoplastics pipes about?  
Thermoplastics pipes are lightweight and durable which makes them popular. 
ISO 9967 specifies a test method for determining the creep ratio of thermoplastics pipes having a circular cross-section. 
Who is ISO 9967 - Creep ratio of thermoplastics pipes for?  
ISO 9967 on creep ratio 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 9967 - Creep ratio 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 9967 walks you through the process to determine the creep ratio of thermoplastics pipes. ISO 9967 provides guidance on: 
- Symbols 
- Dimensional measuring devices
- Marking and number of test pieces
- Length of test pieces
- Inside diameter of test pieces
- Age of test pieces
- Deflection/time plot for one test piece
The guidelines in ISO 9967 help you to run the test for evaluating the creep ratio of thermoplastics pipes to determine their longevity, so that end customers can use superior quality products.
