What is BS 2782-11: Method 1108A – Testing methods for TIR of thermoplastics about? 
BS 2782-11 is a British Standard that discusses the Method 1108A for determination of true impact rate (TIR) of thermoplastics.
Method 1108A has been prepared under the direction of the Plastics Standards Committee.
Method 1108A is one of a series of methods described in BS 2782-11 for assessing the true TIR of thermoplastic pipes, their fittings and valves.
BS 2782-11: Method 1108A describes a method for determining the resistance of plastics pipes to external blows.
Who is BS 2782-11: Method 1108A - Testing methods for TIR of thermoplastics for? 
BS 2782-11: Method 1108A on true impact rate of thermoplastics is relevant to: 
- Manufacturers of thermoplastic pipes, fittings and valves
- Manufacturers of thermoplastic materials
- Plastic industry
- Product designers/product development teams
- Quality control and testing authorities
Why should you use BS 2782-11:Method 1108A- Testing methods for TIR of thermoplastics?
BS 2782-11: Method 1108A provides the best industry guidance on the testing method that determines the TIR of thermoplastics.
BS 2782-11: Method 1108A is suitable for application to isolated batches of pipes, to obtain an estimate of the TIR of the batch, for production quality control or acceptance purposes. In particular this method determines TIR boundaries at the 10 % level when tests are conducted at 20 °C.
Thus, BS 2782-11: Method 1108A can help evaluate whether or not your product is fit for its intended end-use application, such that product failures can be avoided. Moreover, this assessment can make a positive contribution towards your product development initiatives and quality management systems.
