Health and safety in welding and allied processes - Transparent welding curtains, strips and screens for arc welding processes (ISO 25980:2023)

This document specifies safety requirements for transparent welding curtains, strips and screens to be used in workplaces where arc welding is taking place. They are intended to provide protection against harmful levels of optical radiation and spatter for workers who are in the vicinity of arc welding processes but not involved in the welding itself. They are intended to reduce the discomfort glare from the arc but also allow sufficient luminous transmittance to permit a view into the workspace behind.
The transparent welding curtains can also be used in other applications as long as the UV- and blue-light emissions are less than in arc welding and the transmitted infrared irradiance is below applicable exposure limits. They are designed to be used at a distance from the arc of at least 1 m.
Welding curtains, strips and screens specified in this document are not intended to replace welding filters. For intentional viewing of welding arcs, other means of protection are used, see ISO 16321-1 and ISO 16321-2.
This document is not applicable to protection against laser radiation, for which ISO 19818-1 applies.

Arbeits - und Gesundheitsschutz beim Schweißen und bei verwandten Verfahren - Durchsichtige Schweißvorhänge, -streifen und -abschirmungen für Lichtbogenschweißprozesse (ISO 25980:2023)

Dieses Dokument legt sicherheitstechnische Anforderungen für durchsichtige Schweiß-vorhänge,  streifen und  abschirmungen fest, die an Arbeitsplätzen verwendet werden, an denen Lichtbogenschweißen durchgeführt wird. Sie sollen Arbeiter, die sich in der Nähe der Lichtbogenschweißprozesse befinden, jedoch nicht aktiv an dem Schweißvorgang beteiligt sind, vor schädlichen Niveaus optischer Strahlung und Spritzern schützen. Ferner sollen sie die unangenehme Blendung durch den Lichtbogen vermindern und gleichzeitig einen ausreichenden Lichttransmissionsgrad bieten, der einen Einblick in den dahinterliegenden Arbeitsplatz ermöglicht.
Die durchsichtigen Schweißvorhänge können auch bei anderen Anwendungen verwendet werden, sofern die UV  und Blaulichtstrahlungsemissionen geringer als beim Lichtbogenschweißen sind und die durchgelassene infrarote Bestrahlungsstärke unter den geltenden Expositionsgrenzwerten liegt. Sie sind dafür bestimmt, in einem Abstand von mindestens 1 m zu dem Lichtbogen eingesetzt zu werden.
Schweißvorhänge,  streifen und  abschirmungen, die in diesem Dokument festgelegt sind, sind kein Ersatz für Schweißerschutzfilter. Für die beabsichtigte Betrachtung von Schweißlichtbögen werden andere Schutzvorrichtungen verwendet, siehe ISO 16321 1 und ISO 16321 2.
Dieses Dokument ist nicht auf den Schutz vor Laserstrahlung anwendbar, für die ISO 19818 1 gilt.

Hygiène et sécurité en soudage et techniques connexes - Rideaux, lanières et écrans transparents pour les procédés de soudage à l'arc (ISO 25980:2023)

Le présent document spécifie les prescriptions de sécurité relatives aux rideaux, lanières et écrans de soudage transparents destinés à être utilisés sur les lieux de travail où du soudage à l'arc est réalisé. Ils sont destinés à assurer la protection contre les niveaux nocifs de rayonnement optique et contre les projections, des travailleurs qui se trouvent à proximité des procédés de soudage à l'arc mais qui ne prennent pas part au soudage lui-même. Ils sont destinés à réduire l'éblouissement inconfortable provenant de l'arc, mais ils permettent également un facteur de transmission dans le visible suffisant pour permettre une vue sur l'espace de travail situé derrière.
Les rideaux de soudage transparents peuvent également être utilisés dans d'autres applications, pour autant que les émissions de lumière bleue et UV soient inférieures à celles du soudage à l'arc et que l’éclairement énergétique infrarouge transmis soit inférieur aux limites d'exposition applicables. Ils sont conçus pour être utilisés à une distance de l'arc d'au moins 1 m.
Les rideaux, lanières et écrans de soudage spécifiés dans le présent document ne sont pas destinés à remplacer les filtres de soudage. Pour l'observation intentionnelle des arcs de soudage, d'autres moyens de protection sont utilisés, voir l’ISO 16321-1 et l’ISO 16321-2.
Le présent document ne s’applique pas à la protection contre les rayonnements laser pour laquelle l'ISO 19818-1 s'applique.

Varnost in zdravje pri varjenju in sorodnih postopkih - Prosojne zavese, trakovi in zasloni pri postopkih obločnega varjenja (ISO 25980:2023)

Ta dokument določa varnostne zahteve za prosojne zavese, trakove in zaslone za zaščito delovnih mest pri postopkih obločnega varjenja. Ti izdelki so namenjeni zaščiti pred škodljivimi ravnmi optičnega sevanja in obrizgom delavcev, ki so v bližini mesta izvajanja obločnega varjenja, pri čemer sami varjenja ne izvajajo. Namenjeni so za zmanjševanje neprijetnega bleščanja obloka, obenem pa omogočajo zadostno prepustnost svetlobe, da je skoznje mogoče videti delovno mesto.
Prosojne zavese je mogoče uporabiti tudi za druge namene pod pogojem, da so emisije UV-svetlobe in modre svetlobe manjše kot pri obločnem varjenju in je prepustnost infrardečih žarkov pod veljavnimi mejnimi vrednostmi za izpostavljenost. Zasnovane so za uporabo na razdalji vsaj 1 m od obloka.
Zavese, trakovi in zasloni, opisani v tem dokumentu, niso predvideni kot zamenjava za filtre za varjenje. Za namerno gledanje v varilni oblok se uporabljajo druga sredstva za zaščito (glej standarda ISO 16321-1 in ISO 16321-2).
Ta dokument se ne uporablja za zaščito pred laserskih sevanjem, za katero se uporablja standard ISO 19818-1.

INTERNATIONAL STANDARD ISO 25980:2023(E)
Health and safety in welding and allied processes —
Transparent welding curtains, strips and screens for arc
welding processes
1 Scope
This document specifies safety requirements for transparent welding curtains, strips and screens
to be used in workplaces where arc welding is taking place. They are intended to provide protection
against harmful levels of optical radiation and spatter for workers who are in the vicinity of arc welding
processes but not involved in the welding itself. They are intended to reduce the discomfort glare from
the arc but also allow sufficient luminous transmittance to permit a view into the workspace behind.
The transparent welding curtains can also be used in other applications as long as the UV- and blue-
light emissions are less than in arc welding and the transmitted infrared irradiance is below applicable
exposure limits. They are designed to be used at a distance from the arc of at least 1 m.
Welding curtains, strips and screens specified in this document are not intended to replace welding
filters. For intentional viewing of welding arcs, other means of protection are used, see ISO 16321-1 and
ISO 16321-2.
This document is not applicable to protection against laser radiation, for which ISO 19818-1 applies.

4 Requirements
4.1 Transmittance
4.1.1 Infrared transmittance
This document does not provide infrared transmittance requirements. The intensity of the infrared
radiation from the welding arc at a distance of more than 1 m is too low to represent a hazard.
Annex A provides information on the basis of the transmittance requirements of this document.
4.1.2 Effective ultraviolet transmittance
When tested in accordance with 5.1.2, the weighted effective ultraviolet transmittance, τ , in the
UV
wavelength range between 200 nm and 400 nm shall be less than 0,002 %.
NOTE Measurement of spectral transmittance at wavelengths below 250 nm creates measurement problems
with noise. Most plastic materials (e.g. PVC and PC) have a very high attenuation and provide sufficient protection
at wavelengths < 250 nm.
4.1.3 Effective blue-light transmittance
When tested in accordance with 5.1.3, the weighted effective blue-light transmittance, τ , in the
B
wavelength range between 300 nm to 700 nm shall be less than 1,0 %.
4.1.4 Luminous transmittance
When tested in accordance with 5.1.4, the classification based on the luminous transmittance can be
expressed in the grades according to Table 1. Annex B provides information on the selection of curtain
and grade.

NOTE The maximum values are taken as equal to or less than and the minimum values are taken as greater than.
a
Extra dark is normally intended for separation of adjacent operations.
4.2 Resistance to ultraviolet radiation
To ensure that the required protection is maintained and the discomfort glare protection is not
markedly altered after exposure to UV radiation, the curtain shall be exposed to a xenon arc that has
similar spectral characteristics to welding arcs.
After exposure to UV radiation due to the test specified in 5.2, the curtain shall remain in conformity
with 4.1.2 and 4.1.3 and the relative change in luminous transmittance shall not be greater than ± 20 %.
4.3 Resistance to flame spread
When tested in accordance with 5.3.3, the welding curtain, strip or screen material is considered to be
satisfactory if for all three samples:
— the flame does not reach the test mark with the burner in position;
— the flame self-extinguishes after removal of the burner;
— the material does not co
