BS ISO 4433-1:1997

This standard BS ISO 4433-1:1997 Thermoplastic pipes. Resistance to liquid chemicals. Classification is classified in these ICS categories:

• 23.040.20 Plastics pipes

1.1 This part of ISO 4433 specifies a method for carrying out a preliminary evaluation of the behaviour of thermoplastics pipes in relation to the liquid chemicals transported.

1.2 This method of classification provides information on the suitability of pipes for transporting liquid chemicals in the absence of pressure or stresses such as earth loads, dynamic stresses and internal stresses.

1.3 A full procedure for carrying out the test is also reported in ISO 175, which is devoted to plastics in general, and not specifically to thermoplastics pipes.
