标准范围
This document, in conjunction with ISO 11299-1, specifies requirements and test methods for close-fit
lining systems intended to be used for the renovation of gas supply networks.
It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable
to polyethylene (PE) pipe of either solid wall single layer or co-extruded layer construction, which is
reduced in the factory or on site to provide a close-fitting independent or interactive pressure pipe
liner, as well as associated fittings and joints for the construction of the lining system. This document is
not applicable for coated PE pipes having a peelable, contiguous, thermoplastics additional layer on the
outside of the pipes.
It is applicable to PE pipes, fittings and assemblies intended to be used at an operating temperature of
20 °C as the reference temperature.
NOTE For other operating temperatures, guidance is given in ISO 4437-5:2014.
