WORKWEAR RATINGS
The key reason for wearing FR clothing is to ensure that the garments do not catch fire and/or to limit flame spread, thereby giving time to react in the event of an accident. There are different certifications and symbols for different risks and Ironclad Performance Wear want to make sure you choose the right combination that fits your risk assessment. All Ironclad Performance Wear PPE (Personal Protective Equipment) clothing follows the PPE directive 89/686/EEC and the latest European (EN) standards for PPE clothing covered by the directive; in addition to this our garments meet the requirements for NFPA2112 and NFPA 70E.
There are 3 categories within the PPE directive/PPE legislation:
- Category I - Low risk of injury (E.G. rain protection EN 343)
- Category II - Risk of injury (E.G. EN ISO 11612 A, B, C, Heat & Flame)
- Category III - High risk of injury (E.G. electric ARC IEC 61482-2, molten metal EN ISO 11612 D3, E3)
CE MARKING FOR PROTECTIVE GARMENTS
All Ironclad Performance Wear garments are CE marked. The CE marking indicates that a notified body has CE type examined these garments according to the PPE directive 89/686/EEC or the PPE legislation (EU) 2016/425. You will find this symbol on the inside CE label. The CE label also shows which standards and classes the garments are appproved for.
ISO 11612 : PROTECTIVE CLOTHING TO PROTECT AGAINST HEAT AND FLAME
NFPA2112 : PROTECTIVE CLOTHING TO PROTECT AGAINST FLASH FIRE
This standard specifies PPE clothing when working where there is a risk that the garments will come into contact with heat and flame. The standard is divided in different categories, where the code letters show which heat and flame requirements the garment needs to fullfill. At least two categories must be tested to be able to CE mark the garments. Code letter A1 and/or A2 is mandatory and the result is included on the CE label together with this symbol. The code letters are classified in different levels where the highest number is the highest tested level. The design of the garment is also a parameter in the CE marking for heat and flame garments.
- A1, A2 - Requirements for limited flame spread; A1: Surface ignition. A2: Edge ignition
- B (1-3) - Protection against convective head and open flames
- C (1-4) - Protection against radiant heat
- D (1-3) - Protection against molten aluminum splash
- E (1-3) - Protection against molten iron splash
- F (1-3) - Protection against contact heat
EN ISO 11612 is an International Standard also approved by the U.S. The American Standard for protection against heat and flame is called NFPA 2112. The biggest difference in the American Standard is the char length test and that some tests are done after 100 washes. NFPA 2112 provides minimum performance criteria and sets clear guidelines for minimum design, performance, certification requirements and test methods for flame resistant garments for use in areas at risk from flash fires such as those where flammable gases or vapours, or combustible dusts might be present.
The standard calls for flash fire testing to be conducted at three seconds with a pass/fail rate of 50% total body burn under ASTM F1930 (Standard test method for evaluation of flame-resistant clothing for protection against flash fire simulations using an instrumented manikin) testing protocols.
IEC 61482: PROTECTIVE CLOTHING AGAINST THE HAZARD OF AN ELECTRIC ARC
ASTM1959: THE TEST METHOD USED TO CALCULATE ARC RATINGS FOR FR FABRICS
This standard specifies PPE clothing when there is a risk of an electric ARC - For instance when working with electricity on open equipment or maintenance / switching work. Electric ARC garments come under PPE directive / PPE Legislation Category III. Fabric properties and garment design are important parameters in the certification process of electric ARC garments. EN 61482-1-1 "Open ARC Test" involves a medium voltage range (>1000V) and EN 61482-1-2 "BOX TEST" involves a low voltage range (400V). Both tests simulate different levels of risks.
EN 61482-1-1 Open ARC Test - This tests the protection level of the garment by using an open ARC, very similar test method is applied under ASTM F1959/F1959M-14 although pre-treatments may vary. The open ARC test results in an ARC rating; ATPV value (ARC Thermal Performance Value) and/or EBT 50 value (Energy Break Open Threshold). This is an ARC rating system for the FR fabric/fabric layers. The result is given in CAL/CM² and means that at this energy the garment is predicted to protect from a second-degree skin burn (with a 50% probability). The value helps you to choose the right level of protection.
EN 61482-1-2 Box Test - This tests the protection class of the garments by using a constrained and direct ARC. Class 1 - 168 KJ (4 KA, 400V) & Class 2 - 320 KJ (7 KA, 400V). A single layer garment will in most cases pass Class 1. To reach Class 2, A Two or Three layer system (or a thicker garment such as a winter garment) is needed.
NFPA70E: THE STANDARD FOR ELECTRICAL SAFETY IN THE WORKPLACE
The American NFPA 70E standard for electrical safety in the workplace is a consensus standard on how to protect workers from the hazards of an electric ARC. NFPA is designed to help employees and workers to understand electrical hazards, it helps with: hazard assessment, ARC PPE selection and electrical safe work practices. The ARC rating is divided into four PPE categories. It is normally recommended that the outer layer reaches 8 CAL/CM² (I.E. PPE 2/CAT 2).

EN 1149: PROTECTIVE CLOTHING WITH ELECTROSTATIC PROPERTIES
The standard specifies PPE clothing used in explosive environments (I.E. ATEX) where there is a risk that the garments could create sparks (source of ignition), which in turn could ignite explosive materials. To certify garments to this standard, the anti-static properties of the fabric are tested according to EN 1149-1(Surface Resistivity) or EN 1149-3 (Charge Decay). The design of the garment is also a parameter in the certification and CE marking of anti-static/ATEX garments.
EN ISO 11611: PROTECTIVE CLOTHING FOR USE IN WELDING & ALLIED PROCESSES
This standard specifies PPE clothing used in welding work or allied processes where you have the risk of spatter (small splashes of molten metal), short contact with flame, radiant heat from the ARC, and risk of electric shock by short-term, accidental contact with live electrical conductors (at voltages up to approximately 100v DC in normal conditions of welding). The standard is divided in two different classes with different levels of protection. The welding function of the fabric is tested with 15 drops (Class 1) or 25 drops (Class 2) of molten metal. The design of the garment is also a parameter in the CE marking of welding garments.
- Class 1 - Protection against the less hazardous welding techniques and situations, causing lower levels of spatter and radiant head
- Class 2 - Protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat
