Individual protections of eyes and face for the soldering and related techniques. - NF IN 175: 1997

Compulsory tests and examinations :

General requirements (175-EGE)


Dimensions (glasses masks for the soldering and the glasses with branches for the soldering) (175-CV04)

Accreditation # 1-1497 Scope available on www.cofrac.fr


Dimensions (screens with hand for the soldering) (175-CV05)


Checking of the headband (175-ST01)

Accreditation # 1-1497 Scope available on www.cofrac.fr

This test enables us to check the sample’s headband.

The sample is compliant if the headband is at least 10 mm wide over the whole section likely to be in contact with the user’s head, and if it is adjustable or self-adjustable.


Area of protection of screens with greenhouse head for the soldering and welders' facial screens gone up on safety helmet (175-CV06

Accreditation # 1-1497 Scope available on www.cofrac.fr


Reinforced toughness (175-SR07)

Accreditation # 1-1497 Scope available on www.cofrac.fr

This test enables us to verify the resistance of a whole protector to front and side impacts of a steel ball, of a nominal diameter of 22 mm, with a mass of 43g, hitting them at a speed of around 5.1m/s.

The sample is compliant if no fracturing or deformation of the eyepiece is observed.


The resistance in the deteriorations (175-DCE1)


Reflectance of the light of screens for the soldering (175-RLE1)


Dimming of the light of screens for the soldering (175-ALE1)


Electric insulation of screens for the soldering only (175-IEE1)


Resistance to ignition (175-RI02)

Accreditation # 1-1497 Scope available on www.cofrac.fr

The aim of this test is to check the behaviour of eye protection equipment or of a pair of ophthalmic spectacles on the contact of an arm mounted at 650 °C.

The sample is compliant if it doesn’t catch fire, and if it does not continue to glow after the flame source has been removed.


The Resistance in the penetration of robust warmthes of screens for the soldering (175-PSC1)


Resistance to corrosion (175-RC01)

Accreditation # 1-1497 Scope available on www.cofrac.fr

This test enables us to test the resistance of personal eye protection equipment (with metal parts) to corrosion, in an aqueous solution.

The sample is compliant if no oxidation or appearance fault is observed.


Adequacy of the methods of cleaning and disinfection (175-AND1)


Mass of the screens (175-ME01)


Majorities, regulation and replacement of harnesses for screens with greenhouse head for the soldering (175-GRR1


Marking and information control (175-MI08)

Accreditation # 1-1497 Scope available on www.cofrac.fr

All markings (eyepieces and frames) must be clear and permanent. Marking must be visible when the full protector is assembled and it must not infringe upon the minimum field of vision. Outside this zone, markings must not obstruct the wearer’s sight.

Oculars' marking must have the technical informations appropriated : level's number, manufacturer's identification, optical class, resistance to the electric arc of short-circuit, not adherence to melted metal and resistance to penetration of the robust warmthes penetration, resistance to damage by fine particles, resistance to fogging, original ocular/replacement ocular, resistance to high speed particles at elevated temperature, brandmark of oculars laminated.

The marking of frames must have the technical informations appropriated : manufacturer's identification, number of this european standard, domain of utilisation, robustness and resistance to high speed particles, resistance to high speed particles at elevated temperature, frames for little head, heigher level's number of ocular.

Eye guard whose frame and oculars form a whole, must have a marking on the frame. This marking must have the complete marking of ocular, one hyphen, the number of this standard and the suited symbols indicating the domain of use and the level of impact.



Optional tests and examinations :

Protection against particles thrown at a high speed (175-PGV1)

Accreditation # 1-1497 Scope available on www.cofrac.fr

This test enables us to test the resistance of personal protection equipment to particles thrown at a high speed, up to 120 m/s.

The eyepiece is compliant if the sample does not become deformed, does not break, this applying also to the eyepiece housing and the frame, and if the side protection is not defective.


Protection against the molten metal and the robust warmthes (175-MFS1)

Accreditation # 1-1497 Scope available on www.cofrac.fr


Protection against electric arc of couts-circuits (175-PACC)

Accreditation # 1-1497 Scope available on www.cofrac.fr


Protection against the gas and the fine particles of dust (175-PFP1)

Accreditation # 1-1497 Scope available on www.cofrac.fr


Protection against the big particles of dust (175-GPP1)

Accreditation # 1-1497 Scope available on www.cofrac.fr


Stability in the dumping in the water of screens with hand for the soldering only (175-SIM1)


Stability in the dumping in the water of screens with headband for the soldering only (175-SIT1)


Release of Nickel (175-LN02)

Accreditation # 1-1497 Scope available on www.cofrac.fr

This test enables us to measure the rate of nickel released by the different parts of metal frames (rounds, bridges and arms).

For a sample to be compliant, the measured rate of nickel released from the entire frame, must be less than 0.5 µg/cm²/week.
