This document specifies definitions, principles of construction, requirements and methods for testing the performance of UV devices (240 nm to 290 nm nominal) for potable water installations according to EN 806-2 which are permanently connected to the building’s supply. Devices described by this document can be installed at the point of entry (POE), within the water distribution system inside the building or at the point of use (POU). Additionally, the devices described in this document can be used in mobile or temporary potable water installations, where the system is not permanently connected to a water supply. UV devices in the sense of this document are UV bactericidal treatment devices or UV disinfection devices for one of three specified water qualities, determined by the observed UV transmittance. Devices can be standalone, integrated into a larger appliance or part of multi-staged treatment process. The document relates solely to the performance of the UV reactor.

This document describes a field method for measuring the surface profile produced by any of the abrasive blast-cleaning procedures given in ISO 8504-2:2019. The method uses replica tape and a suitable gauge for measuring the roughness of a surface before the application of paint or another protective coating.

The method is applicable within the range of profile heights cited for a given grade (or thickness) of replica tape. The commercial grades currently available permit measurement of average peak-to-valley profiles of 12 µm to 150 µm. The method is valid for surfaces that have been cleaned with abrasives.

This document specifies the functional requirements and principles for design, operation and requalification of pipelines in the petroleum and natural gas industries using reliability-based limit state methods as permitted by ISO 13623. Reliability-based limit state methods provide a systematic way to predict pipeline safety in design and operation. This document supplements ISO 13623 and can be used in cases where ISO 13623 does not provide specific guidance and where limit states methods can be applied, such as, but not limited to, — qualification of new concepts, e.g. when new technology is applied or for design scenarios where industry experience is limited, — re-qualification of the pipeline due to a changed design basis, such as service-life extension or change of the transported fluid, which can include reduced or increased uncertainties due to improved integrity monitoring and operational experience or limited information on pipeline properties relevant to the new service — collapse under external pressure in deep water, — extreme loads, such as seismic loads (e.g. at a fault crossing), ice loads (e.g. by impact from ice keels), — situations where strain-based criteria can be appropriate. This document applies to rigid metallic pipelines on-land and offshore used in oil and gas industries including lower carbon energy.
