What is ISO 11611?
This standard applies to clothing designed for the protection of the wearer against various spattering, welding hazards through equipment that protect from sparks, these clothing protect from flashing heat emitted from an electrical arc used to weld metals and associated procedures, thus mitigating the option of electrical shock due to accidental brief connection with live conductors of electricity at voltages. This standard is to maintain quality of the protective clothing.
ISO 11611 sets minimum protective clothing security requirements to protect the body of the wearer, this standard includes clothing like aprons and sleeves. This does not apply to the equipment for the security of the feet, hands, face or eyes – specifications are specified in other global standards.
With the authorization of EN ISO 11611, the safety clothing wearer must be secured from electricity, brief contact with fire and of the risk of electrical shock from brief unintended touch with electrical conductors. Workwear needs to cover up the entire body in order to provide maximum protection.
The jacket and matching trousers are used for this purpose. When using metal welding methods which generate a lot of sparks, we recommend additional protection for the clothes ‘arms, hands and forward-facing. In order to prevent sparks on the workwear, only a small number of pockets and additional functions are included in the protective clothing approved in compliance with EN ISO 11611, thereby eliminating fire trappings.
What is ISO 11612?
This Global Standard sets the standard for protective clothing consisting of various fabrics designed for the protection of the person’s body from fire and heat excluding the face. Socks, hoods, and overboots are the only safe accessories protecting the wearer’s head and foot within the context of this Global Norm. Nonetheless, the eye safety and inhalation gear hood specifications are not stated.
The uniform applies to lightweight gear, which may be used on various purposes. The garments must have a negligible flaming susceptibility so that the user can be shielded from flashing or broadcasting, or touching flame or spattering molten metal.
The Norm is not defined by other Global guidelines for defense squad.
How does a company get an ISO 11612 certificate?
The fabric which is marked durable, must pass two tests to achieve EN ISO 11612 standard: The tests A, and the test B, C, D or test E. The quality of the fabric is achieved by test.
• A Test: Fire spread
• B Test: Transmission heating
• C Test: Thermal radiation
• D/E Test: Melted metal
• F Test: Contact heat
Assessment results are broken down into performance groupings. For example, level 1 designates the minutest security needed for fabric to be effective in a study. Not only is it advisable to check if a product passes the test but also to what extent you are accountable for the protective clothing of your business.
The face, waist, shoulders, back and the legs must be covered with sweater, vest and overall. It is required to maintain a gap of 20cm between the pants and the jacket during job operations. More distinguishing criteria are necessary for codes D & E.
The specific output levels are significant to remember because they contribute to the nature of the threat involved. For eg, the three efficiency thresholds for the test E should warn you of melted iron spill safety in various amounts: E1 views for 60 – 120 g iron spills and E3 views for above 200 g. You ought to select the right performance level depending on the amount of risk in the job environment.
Basic necessities: the material should not be ignited or melted at 180 ° C fire resistance and should not be decreased by more than 5%. The criteria must fulfilled by the material, for at least tolerance to tearing and scratching.
Test on dummies
The test is performed with the optional ISO 13506 certification by the test companies and groups in your area. The fabric is washed many times before being tested on the manikin, as the washing diminishes and the fabric becomes less effective. The search takes 3 seconds, but will continue if requested, and other businesses have different documents to market their goods from. They must however be checked standard in EN ISO 11612. This doesn’t appear to be a big change, producing another energy of 84 kJ per mtr2/sec not a second for an extra second. The temperature ranges between 800 and 1000 ° C throughout the production process. The appropriate protective garments must protect the head, chest, hands & feet to ensure maximum protection. Note that the specified above should also be worn with combination of outer apparel that complies with EN 11612 health requirements. On its own the underwear does not provide the right amount of security.
