This document describes the general principles for the implementation and management of a system of cathodic protection against corrosive attacks on structures which are buried or in contact with soils, surface fresh waters or underground waters, with and without the interference of external electrical sources. It specifies the protection criteria to be achieved to demonstrate the cathodic protection effectiveness.
For structures that cannot be electrically isolated from neighbouring influencin...view more

This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks.
It applies to spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, and i...view more
