How a company can get ISO 11611 & ISO 11612 Certificate?


Quick Overview of ISO 11611

This Custom refers to clothing designed to protect the wearer from a spattering of different welding devices simulated short contact time with fire, radiant heat from an electrical arc used for welding and related processes, thereby reducing the risk of electrical shock due to unintended short contact with live electrical conductors at voltages. This Standard is valid under normal welding conditions for the wearer.

ISO 11611 sets minimum safety clothing performance standards to protect the wearer’s body, including aprons, two-grade sleeves that reflect the two-degree exposure of a spill. This does not address the criteria of feet, hands, face or eye protection–specifications are defined in other international standards.

With EN-ISO-11611 authorized, the safety wearer must be protected against sparks, short fire contact and the possibility of electrical shock from short accidental communication with electric conductors must be reduced. The entire body must be covered with workwear to get full protection.

For this reason, the jacket and matching pants are used. While applying welding techniques, creating a lot of sparks, it is suggested to use special protection for arms, hands, and exposing parts of the clothes. To prevent workwear from sparks, only a limited pockets and functions are included in safety apparel accepted according to EN-ISO-11611, thereby avoiding trapping of sparks.

Quick Overview of ISO 11612

This International Standard sets out the standard of protective garments made of various materials that are intended to protect the body of the wearer from heat and flame except for the face. The only protective footwear that covers the wearer’s head and foot within the scope of this International Standard are socks, hoods, and overboots. Nonetheless, hood requirements for the visor and breathing equipment are not stated.

The norm refers to protective clothing and can be used in many ends uses. The clothing needs to have a minimum flaming propensity so the user may be exposed to radiant or convective or contact heat or molten splashing of metal. The Standard is not for protective clothing specified by other International Standards.

How does a fabric have an
ISO 11612 certificate?

To meet the EN-ISO-11612 standard, the durable fabric must pass a minimum of two tests: the A test, and the B, C, D, or E test. The fabric output is noted per check.

Test A: Flame spread

Test B: Convective heating

Test C: Radiant heat

Test D/E: Molten metal

Test F: Contact heat

The findings of the evaluation are broken up into output groups. Level 1 shows, for example, the minimum protection required for passing a check in the fabric. It is not only advisable to see if a fabric passes the test, but also to what extent if you are responsible for your company’s protective clothing.

Jacket, pant and overall will cover the chest, stomach, back, arms, and legs. A 20 cm gap between the jacket and the pants is expected during all the work operations. Metal elements should not become directly in contact with the wearer’s skin. For code letters D and E, more identifying requirements apply.

The different performance rates are important to consider as they are related to the severity of the risk involved. For example, the three efficiency levels for the E-test notify you in different amounts about protection against molten iron splash: E1 stands for iron slashes of 60 to 120 grams and E3 stands for over 200 grams. You have to select the best output level based on the level of risk in your work environment.

General requirements: heat resistance at 180 ° C: the material must not be ignited or melted and must not be decreased by more than 5%. The material must meet a minimum tearing and abrasion resistance requirement

Dummy test

That fabric is conducted by the test groups and companies in your region with the optional ISO 13506 certification. Before testing on the manikin, the fabric is washed a couple of times, as washing decreases and makes the fabric less efficacious. The check will take 3 seconds, but if desired, it can proceed and many companies have different records on which to sell their products. However, they must be standard tested in EN ISO 11612. It doesn’t seem to be a huge difference, only a second but one additional second generates another 84 kJ of energy per mtr2/sek. Throughout manufacturing, the temperatures vary between 800 to 1000 ° C.

Any protective clothing required must cover the head, body, hands, and feet to ensure maximum protection. Remember that underwear listed clothing should always be worn in conjunction with outer clothing which complies with the safety specifications of EN 11612. The underwear on its own doesn’t offer the right level of protection.
