The purpose of this document is to:
—   identify and describe, in a structured way, the principles of the integrated logistic support (ILS) activities and tasks for the main types of stakeholders in the system life cycle, from the expression of need to disposal;
—   place the activities, tasks and ILS deliverables within the programme execution;
—   identify the main selection and sizing of activities and tasks criteria according to the nature and the requirements of the programme;
—   control the relations with the other aspects of programme management.
This document covers the following subjects:
—   management of ILS (definition, implementation and running of the processes);
—   expression of the support requirements;
—   elaboration of the contracts (e.g. for development, maintenance, supply);
—   implementation of the tasks and processes.
This document is also related to the following subjects:
—   relations with costs and lead times control, configuration management, performance and RAMS management, quality assurance, documentation management;
—   regulations (e.g. information system security, export controls, safety at work);
—   human and organizational factors (HOF);
—   environment (e.g. RoHS, REACh);
—   information systems (IS) and the links between them;
—   logistics information systems (LIS);
—   in-service support (ISS) activities;
—   configuration management of ILS objects;
—   life cycle.
The following stakeholders are concerned by ILS:
—   users in the broadest sense: operators, maintenance operators, administrators, dismantlers of the system, trainers;
—   the customer, who:
—   prepares technical and contractual specifications of need with which the system will comply;
—   sets up the funding of the programme;
—   oversees the realization and commissioning of the main system and of the support system;
—   facilitates the feedback.
NOTE 1   At the highest level of the system, the customer can also be referred to as the “project owner”.
NOTE 2   The “main system” can also be referred to as the “system of interest”.
—   the supplier(s) who deliver a system (main and support) to the customer, which meets the performance specifications on time and for the agreed cost, throughout the system life cycle;
NOTE 3   At the highest level of the system, the supplier can also be referred to as the “industrial prime contractor”.
—   the regulatory authorities that supervise and approve the support processes and equipment, as needed.
The principles laid down in this document can be applied, after adaptation, to all the customer/supplier relations resulting from the breakdown of the main contract into sub-contracts.

This document specifies the technical delivery requirements for seamless and welded butt welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of carbon and alloy steel in two test categories which are intended for pressure purposes at room temperature, at low temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases.
It specifies:
a)   type of fittings;
type A: Butt-welding fittings with reduced pressure factor;
type B: Butt-welding fittings for use at full service pressure;
b)   steel grades and their chemical compositions;
c)   mechanical properties;
d)   dimensions and tolerances;
e)   requirements for inspection and testing;
f)   inspection documents;
g)   marking;
h)   protection and packaging.
NOTE   The selection of the appropriate fitting (material, thickness) is the ultimate responsibility of the manufacturer of the pressure equipment (see European Legislation for Pressure Equipment). In the case of a harmonized supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently, it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.

The content of the corrigendum 1 of amendment 1 (2025-12) applies only to the French version.

This document provides the framework and principles for the energy resilience of organizations, to help reduce impacts and ultimately achieve a build back better goal after disruptive events, including natural and human-made disruptions. It covers broad resilience engineering and management principles applicable to an energy supply network that includes social and technical considerations. This document does not provide guidance on the application of these principles for engineering design, which require specialized considerations to address risks and define resilience measures. This document is intended to be used by organizations responsible for, or participating in, energy supply networks.
