Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee

ISO 15012-4:2016(E)
Introduction
Welding and allied processes generate fumes and gases which, if inhaled, can be harmful to human
health. Therefore, control of the fumes and gases generated is to be exercised to minimize worker
exposure.
The most effective method of control is to capture the fumes and gases close to their source before they
enter a worker’s breathing zone or the general workplace environment.
Ventilation equipment used to capture the fumes and gases is to be fit for purpose because inefficient
capture could result in high exposure and can be detrimental to workers’ health. It is important
therefore that it adheres to defined manufacturing, materials and design requirements and gives
warning of malfunction.
This part of ISO 15012 defines the general requirements that are necessary for ventilation equipment
to maintain exposure to fumes at acceptable levels.
This part of ISO 15012 is a type-B standard as stated in ISO 12100.
This part of ISO 15012 is of relevance, in particular, for the following stakeholder groups representing
the market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of this part of ISO 15012
by the above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this part of ISO 15012.
In addition, this part of ISO 15012 is intended for standardization bodies elaborating type-C standards.
The requirements of this part of ISO 15012 can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and
built according to the requirements of that standard, the requirements of that type-C standard take
precedence.

Part 4:
General requirements
1 Scope
This part of ISO 15012 defines the general requirements for ventilation equipment used to control
exposure to fumes generated by welding and allied processes. It applies to the design and manufacture
of all parts of the equipment including hoods, ducting, filter units, air movers, systems that inform of
unsafe operation and workplace practices to ensure safe working with regard to exposure.
Significant hazards are listed in Clause 4. It does not cover electrical, mechanical and pneumatic
hazards.
This part of ISO 15012 is applicable to the following:
— local exhaust ventilation systems (LEV);
— mobile and stationary equipment.
This part of ISO 15012 is not applicable to the following:
— general ventilation, air make up or air movement systems;
— air conditioning systems;
— separation of gases generated by or used by welding and allied processes;
— LEV used for welding and allied processes that generate reactive potentially explosive particles and
atmospheres;
— grinding dust.
This part of ISO 15012 applies to systems designed and manufactured after its publication.
