Welding protection curtain

The soft PVC slats safely shield welding workplaces to protect against UV light, infrared rays, slag splashes and flying sparks. However, a welding protection curtain must not be used to observe the welding process as a substitute for a Welding protection curtain.

DINThe highest demands are placed on the quality of the protective curtains. They may only be produced and sold if they are tested and regularly monitored by an external institute according to the German Industrial Standard (DIN).

JEDI Kunststofftechnik GmbH works closely with the DINCERTCO testing laboratory. The laboratory tests every welding protection curtain on the basis of DIN EN ISO 25980:2015-01 (eye protection category I) and issues a certificate with a validity period of 5 years. Furthermore, a factory inspection is carried out with the assessment of a functioning quality management system.

TÜV Rheinland

At regular intervals, the quality of the welding protection products is confirmed by DINCERTCO.

The certified welding protection types / models are published online in the DINCERTCO database.

We put special attention in the certification exam on:

(Excerpt from DIN EN ISO 25980: 2015-01)


Based on the spectral distribution of the CIE standard illuminant A according to ISO 4007, the light transmittance r must be greater than 1 × 10-6. Stray light that is scattered within 1 ° to the direction of incidence of the radiation must be detected during the measurement. The spectral transmittance must be less than 2 × 10 -5 in the wavelength range between 210 nm and 313 nm and less than 3 × 10 -2 in the wavelength range between 313 nm and 400 nm. In the wavelength range from 400 nm to 1 400 nm, the hazard level G must be less than 1.


When measuring with an integrating sphere, the spectral reflectance must be between 230 nm and 400 nm less than 10% and the light reflectance be less than 10% (based on the spectral distribution of the CIE standard illuminant A according to ISO 11664-2).

UV stability

The relative change in the light transmittance due to the EN 168 test shall not exceed ± 20%. Exceeding this limit is permissible, provided that the hazard level G is not reached or exceeded from 1 to 4.2.


After 15 seconds, the burner must be removed, and observing whether the flame goes out by itself and the material stops to glow within (3) s by observing it. Subsequently, it must be determined by inspection whether the penetration of the flame has reached the test mark of 150 mm above the lower end of the sample according to 4.5.6.


For identification purposes and to be able to use welding curtains, strips and shields as intended, they must be permanently marked. The marking must be clearly visible, with letters at least 10 mm high. The label consists of the number of this International Standard (i.e., ISO 25980), the certification mark (if applicable), the name or brand of the manufacturer, distributor or importer, and the month and year of manufacture.
