This standard specifies a method for testing the impact resistance of fittings by dropping them
onto a rigid surface. For a fitting with seal retaining components, such as seal retaining caps
or rings, the method includes assessment of the watertightness of the fittings when the fixing
elements show disturbance as a result of the test.
This standard is applicable to fittings made from thermoplastics materials intended to be used
for buried and above ground applications.
