BS EN ISO 13260:2011+A1:2017

This standard BS EN ISO 13260:2011+A1:2017 Thermoplastics piping systems for non-pressure underground drainage and sewerage. Test method for resistance to combined temperature cycling and external loading is classified in these ICS categories:

• 23.040.20 Plastics pipes
• 93.030 External sewage systems
• 91.140.80 Drainage systems
• 23.040.45 Plastics fittings

This International Standard specifies two methods for testing pipes and fittings or joints for plastics piping systems intended for use in underground drainage and sewerage systems for their resistance to deformation and leakage, when subjected to sustained external loading in conjunction with the passage of hot water.

Method A involves temperature cycling, by passing hot water and cold water alternately, and is applicable to pipes and associated fittings having a mean outside diameter d _em ≤ 190 mm.

Method B involves passing hot water only, except at intervals specified for measurement of internal deflection, and is applicable to pipes and associated fittings having a mean outside diameter 190 mm <  d _em ≤ 510 mm.
