ISO 15614-7:2016 specifies how a preliminary welding procedure specification for overlay welding is qualified by welding procedure tests.
ISO 15614-7:2016 defines the conditions for execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of variables listed in Clause 8.
ISO 15614-7:2016 applies to all welding processes suitable for overlay welding. In situations where qualification is carried out on a pre-production test piece, the qualification is performed in accordance with ISO 15613 except that, as far as possible, the testing is according to this part of ISO 15614. Building up and repair of parent metal is covered by ISO 15613 or ISO 15614‑1.
This edition of ISO 15614‑7 is applicable to all new welding procedure qualification tests. It does not invalidate previous welding procedure tests made in accordance with previous editions of this part of ISO 15614. Where additional tests are required by the present edition, it is only necessary that those additional tests be carried out on a test piece made in accordance with the existing WPS and this part of ISO 15614.
If buttering is used for welding between dissimilar materials, the welding procedure is qualified in accordance with ISO 15614‑1. This buttering may be required for weld combining different material structure or properties, e.g. joining martensitic steels or ferritic steels with austenitic steels.
Additional tests may be required by application standards.

This document is part of a series of standards dealing with specification and qualification of welding procedures. Annex A gives details of this series of standards, Annex B gives a table for the use of these standards, and Annex C gives a flow diagram for the development and qualification of a WPS.
This document defines general rules for the specification and qualification of welding procedures for metallic materials. This document also refers to several other standards as regards detailed rules for specific applications.
This document is applicable to manual, partly mechanized, fully mechanized and automated welding.
Welding procedures are qualified by conforming to one or more welding procedure qualification records (WPQR). The use of a particular method of qualification is often a requirement of an application standard.
It is assumed that welding procedure specifications are used in production by competent welders, qualified in accordance with the relevant part of ISO 9606 or by competent operators qualified in accordance with ISO 14732.

This document specifies requirements for the content of welding procedure specifications for arc welding processes.
Details of the ISO 15609 series are given in ISO 15607. The variables listed in this document are those influencing the quality of the welded joint.

This European Standard specifies constructional, functional, testing, marking, sizing and documentation requirements of gas pressure regulators:
-   for inlet pressures up to 100 bar and nominal diameters up to DN 400;
-   for an operating temperature range from - 20  °C to +60 °C,
which operate with fuel gases of the 1st and 2nd  family as defined in EN 437:2003+A1:2009, used in the pressure regulating stations in accordance with EN 12186 or EN 12279, in transmission and distribution networks and also in commercial and industrial installations.
"Gas pressure regulators" hereafter will be called "regulators" except in the titles.
For standard regulators when used in pressure regulating stations complying with EN 12186 or EN 12279, the Annex ZA lists all applicable essential safety requirements of the European legislation on pressure equipment except external and internal corrosion resistance for applications in corrosive environment.
This document considers the following temperature classes/types of regulators:
-   temperature class 1: operating temperature range from −10 °C to 60 °C;
-   temperature class 2: operating temperature range from −20 °C to 60 °C;
-   type IS: (integral strength type);
-   type DS: (differential strength type).
This document applies to regulators which use the pipeline gas as a source of control energy unassisted by any external power source.
The regulator may incorporate a second regulator, used as monitor, complying with the requirements in this document.
The regulator may incorporate a safety shut off device (SSD) complying with the requirements of EN 14382.
The regulator may incorporate a creep (venting) relief device, complying with the requirements in Annex E and/or a vent limiter, complying with the requirements in Annex I.
This document does not apply to:
-   regulators upstream from/on/in domestic gas-consuming appliances which are installed downstream of domestic gas meters;

-   regulators for which a specific document exists (e.g. EN 88-1 and EN 88-2, etc.);
-   industrial process control valves in accordance with EN 1349.
The normative Annex G of this document lists some suitable materials for pressure bearing parts, inner metallic partition walls, auxiliary devices, integral process and sensing lines, connectors and fasteners. Other materials may be used when complying with the restrictions given in Table 5.
Continued integrity of gas pressure regulators is ensured by suitable surveillance checks and maintenance. For periodic functional checks and maintenance it is common to refer to national regulations/standards where existing or users/manufacturers practices.
This document has introduced the reaction of the pressure regulators to the specified reasonable expected failures in terms of "fail close" and "fail open" pressure regulator types, but it should be considered that there are other types of failures whose consequences can bring to the same reactions (these risks are covered via redundancy as per EN 12186) and that residual hazards will be reduced by a suitable surveillance in use / maintenance.
In this document, both pressure regulators that can be classified as "safety accessories" by themselves (monitors) according to European legislation on pressure equipment as well as regulators that can be used to provide the necessary pressure protection through redundancy (e.g. pressure regulator with integrated safety shut-off device, pressure regulator + in-line monitor, pressure regulator + safety shut off device) are considered.
The provisions in this document are in line with the state of art at the moment of writing.
