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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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

INTERNATIONAL STANDARD ISO 25980:2014(E)
Health and safety in welding and allied processes —
Transparent welding curtains, strips and screens for arc
welding processes
1 Scope
This International Standard specifies safety requirements for transparent welding curtains, strips, and
screens to be used for shielding of work places from their surroundings where arc welding processes are
used. They are designed to protect people who are not involved in the welding process from hazardous
radiant emissions from welding arcs and spatter.
Welding curtains, strips, and screens specified in this International Standard are not intended to replace
welding filters. For intentional viewing of welding arcs other means of protection are used.
This International Standard is not applicable for welding processes where laser radiation is used.
NOTE Darker welding curtains or screens are advisable for mutual separation of adjacent work places for
reasons of comfort.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 4007:2012, Personal protective equipment — Eye and face protection — Vocabulary
ISO 11664-2:2007, Colorimetry — Part 2: CIE standard illuminants
EN 167, Personal eye-protection — Optical test methods
EN 168, Personal eye-protection — Non-optical test methods
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 4007 and the following apply.
3.1
transparent
characteristic of welding curtains, strips, and screens that admit visibility to the working place without
implying to be glass clear
3.2
hazard level
G
dimensionless number representing the risk exposition to visible and near IR radiations
4 Requirements
4.1 General
For transparent welding curtains, strips, and screens consisting of different materials, all requirements
for the whole material combination shall be met.
ISO 25980:2014(E)
For optical test methods, see EN 167.
After preparation, the test specimens shall be maintained at a temperature of (23 ± 5) °C and relative
humidity of (65 ± 10) % for a minimum of 16 h before testing.
4.2 Transmittance
The luminous transmittance, r, based on the spectral distribution of CIE standard illuminant A according
−6
to ISO 4007 shall be greater than 1 × 10 scattered light diffused within 1° to the direction of the
incident radiation shall be included in the measurement.
The spectral transmittance in the wavelength range between 210 nm and 313 nm shall be less than
−5 −2
2 × 10 , in the wavelength range between 313 nm and 400 nm less than 3 × 10 .
In the wavelength range from 400 nm to 1 400 nm the hazard level G shall be less than 1.
The hazard level is defined by
