It is applicable to piping systems based on thermoplastics pipes intended to be used in hot and cold water applications. 2 Principle while being maintained at a specified temperature and inspected for leakage. NOTE It is assumed that the following test parameters are set by the reference standard (i.e. the standard making reference to this International Standard), as applicable (see Clause 4): a) the test temperature; b) the number of test pieces; c) the test pressure limits; d) the duration of one cycle; (e the number of cycles. 3 Apparatus 3.1 Pressurizing device, capable of applying and regulating the water pressure in the test piece in a sinusoidal or trapezoidal form between pressure limi
