This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes and fittings for the renovation of underground non-pressure drainage and sewerage networks by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout.
This document is applicable to plastics inner layers and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system.
NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.

This document specifies methods used to evaluate the external corrosion hazards of well casings, as well as cathodic protection means and devices to be implemented in order to prevent corrosion of the external part of these wells in contact with the soil.
This document applies to any gas, oil or water well with metallic casing, whether cemented or not.
However, in special conditions (shallow casings: e.g. 50 m, and homogeneous soil), EN 12954 can be used to achieve the cathodic protection and assess its efficiency.

This document specifies fire type-testing requirements and a fire type-test method for valves with one or more obturators. It is not applicable to the testing requirements for valve actuators other than manually operated gearboxes or similar mechanisms when these form part of the normal valve assembly. Other types of valve actuators (e.g. electrical, pneumatic or hydraulic) can need special protection to operate in the environment considered in this valve test, and the fire testing of such actuators is outside the scope of this document.
This document specifies the measurement and assessment criteria for:
a) through-seat leakage;
b) external leakage;
c) cavity overpressure relief of double seated valves;
d) operability.
This document specifies the rules whereby the fire-type testing qualification for a valve can be extended to untested sizes, pressure ratings, and materials of construction of the same basic design type.
Fire test reports of valves tested according to previous editions of ISO 10497 are acceptable when submitted together with the full and compliant fire test report as per 6.7 of the edition under which it was tested. Additional testing is specified for double seated valves where the body cavity relief valve setting was not recorded in the original fire test report.
NOTE For the purposes of this document, the terms “fire type-test” and “fire test” are synonymous.

This International Standard is applicable to ABS, PVC-U or PVC-C pipes, fittings, valves and ancillary equipment, to their joints and to joints with components made of other plastics and non-plastics materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as of solid matter in fluids for industrial applications such as: - chemical plants; - industrial sewerage engineering; - power engineering (cooling and general-purpose water supply); - melectroplating and pickling plants; - the semiconductor industry; - agricultural production plants; - water treatment. NOTE 1 Where relevant, national regulations for specific applications (e.g. water treatment) apply. Other application areas are permitted if the requirements of this International Standard and/or applicable national requirements are fulfilled. Relevant regulations in respect of fire behaviour and explosion risk are applicable if applications are envisaged for inflammable media. The components have to withstand the mechanical, thermal and chemical demands to be expected and have to be resistant to the fluids to be conveyed. Characteristics and requirements which are applicable to all three materials (ABS, PVC-U and PVC-C) are covered by the relevant clauses of this International Standard. Those characteristics and requirements which are dependent on the material are given for each material in the relevant annex.
