This document (prEN 14717:2021) has been prepared by Technical Committee CEN/TC 121 “Welding
and allied processes”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14717:2005.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
The main changes compared to the previous edition EN 14717:2005 are as follows:
a) the document was editorially reviewed;
b) new terms (ecodesign and improvement of the environmental performance) under Clause 2 added;
c) new Annex ZA regarding relationship between this document and the ecodesign requirements of
Commission Regulation (EU) No 2019/1784.

Introduction
Protection of the environment is a key political issue in Europe and elsewhere. Protection of the
environment is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g. a product
on the environment, including expenditure of energy and during all phases from mining of raw materials,
fabrication, packaging, distribution, use, scrapping, recycling of materials, etc. However, assessment of all
aspects of the welded product or structure during its entire lifetime cycle is beyond the scope of the
present document. The document is limited to aspects directly related to welding fabrication.
The design of the fabricated structures puts a lower limit on the expenditure of energy during joint
preparation and welding, on the consumption of consumables and consequently on emissions of fumes
and gases during welding, etc. but the design phase is not covered by the document.
Welding fabrication has many environmental aspects. This document provides for a checklist, which may
be used for identification of environmental aspects during welding fabrication.
Provisions are restricted to a general guidance. Limit values are specified in national laws.
Some of the environmental aspects also have an implication for occupational health and safety, but the
check list in this document is incomplete for this use.

4 Procedures
Requirements for the protection of the environment and improvement of the environmental performance
of welding equipment during welding fabrication can originate from a number of sources such as:
— legal requirements, often at the national level;
— commercial requirements (customer requirements);
— economical requirements, e.g. related to insurance.
Annex B provides further comments on the possible requirements.
Absolute limits, e.g. emissions, can apply but protection of the environment is, as a general rule, a
continuous process for which gradual improvements are aimed.
The check lists in the document can be used as a tool for determination of possible problem areas. In
general this applies to the following situations:
— when planning a fabrication, the application of new methods of fabrication or new equipment;
— for identification of procedures for monitoring or checks of actual environmental aspects;
— for specification of procedures for handling, storage and disposal of environmentally harmful
substances.
All check lists state possible environmental aspects. Many aspects can be identified during the planning
stage as having no environmental impact. Others can be shown to be of no significance by monitoring or

checking the production processes. A few can result in further action to comply with the requirements.
Annex A provides some general guidance for assessment and possible actions.
5 Check lists of possible environmental aspects
Table 1 — Common to welding fabrication
Common to welding fabrication
Consumables Check for:
— Consumption of welding consumables during
welding (filler material, shielding gas, backing gas,
electrode coating);
— Disposal of containers, packaging material, etc.;
— Disposal of used consumables and waste
materials.
Equipment Check for:
— Energy and fuel efficiency;
— Generation of physical aspects, e.g. noise, heat

— Emission of fumes, gases and aerosols;
— Energy and fuel consumption;
— Fire hazards and explosion risks whenever there
is a risk of ignition;
— Generation of physical aspects, e.g. heat, light,
noise, radiation.
Several of the aspects listed above have a limited range of influence. It depends on the
circumstances whether they represent an environmental aspect or not. Noise may e.g. not
represent an environmental aspect when working in a large workshop but could be a serious
problem when working on site or performing repair work in residential areas.
