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.
