EN 1149

ELECTROSTATIC PROTECTION

EN 1149 consists of the following parts:

– EN1149-1: test methods for the measurement of surface resistance

– EN1149-2: test methods for the measurement of the electrical resistance through a material (vertical resistance)

– EN1149-3: test methods for the measurement of charge decay

– EN1149-4: garment test method (standard currently under development)

– EN1149-5: performance requirements.

EN 20471

HIGH VISIBILITY CLOTHING

EN ISO 20471 standard specifies the requirements for clothing designed to emphasize the wearer’s presence visibly in order to make the wearer more noticeable in hazardous situations during the day and at night (illumination in car headlights).

This standard’s icon is a safety vest placed adjacent to a number which represents the design classification of the garment. The classification is 1, 2 or 3 where Class 1 provides the minimal level of visibility and class 3 provides the highest level prescribed by the standard.

EN 61482

PROTECTIVE CLOTHING AGAINST THE THERMAL HAZARDS OF AN ELECTRIC ARC

IEC 61482-2:2009 PERFORMANCE & DESIGN REQUIREMENT

Performance requirements for materials and design requirements for garments, plus Marking and User Information.This part of IEC 61482 is applicable to protective clothing used in work if there is an electric Arc hazard. This standard specifies requirements and test methods applicable to materials and garments for protective clothing worn by electrical workers to protect them against the thermal hazards of electric Arc based on relevant general properties of the textiles, tested with selected textile test methods, and one of the Test Methods as defined below.

IEC 61482-1-1:2009 ‘OPEN ARC’ TEST METHOD

‘Open Arc’ test method (ATPV test and garment test). This replaces IEC 61482-1:2002. The ‘Open Arc’ test method is the same as the original North American method for measuring the Arc Thermal Performance Value (ATPV), as used in ASTM F1959. Materials or assemblies are given an ATPV value, expressed in kilojoules per square metre (kJ/m2), which can be converted into the familiar cal/cm2.

NFPA 70E

Electrical Safety in the Workplace

NFPA 70E addresses employee workplace electrical safety requirements. The standard focuses on practical safeguards that also allow workers to be productive within their job functions. Specifically, the standard covers the safety requirements for the following:

1. Electrical conductors and equipment installed within or on buildings or other structures, including mobile homes, recreational vehicles, and other premises (yards, carnivals, parking lots, and industrial substations)
2. Conductors that connect installations to a supply of electricity

Not covered are – electrical installations in marine, aircraft, auto vehicles, communications and electrical utilities.

Key principles covered are shock protection boundaries, arc flash energies, Lockout-Tagout, PPE (Personal Protective Equipment). While the various OSHA, ASTM, IEEE and NEC standard provide guidelines for performance, NFPA 70E addresses practices and is widely considered as the de facto standard for Electrical Safety in the Workplace.

NFPA 2112

Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire

NFPA 2112 standard shall provide minimum requirements for the design, construction, evaluation, and certification of flame-resistant garments for use by industrial personnel, with the intent of not contributing to the burn injury of the wearer, providing a degree of protection to the wearer, and reducing the severity of burn injuries resulting from short-duration thermal exposures or accidental exposure to flash fires.

The NFPA 2112 standard shall specify the minimum performance requirements and test methods for flame-resistant fabrics and components and the design and certification requirements for garments for use in areas at risk from flash fires.

EN 11611

Protective clothing for use in welding and allied processes

ISO 11611:2015 specifies minimum basic safety requirements and test methods for protective clothing including hoods, aprons, sleeves, and gaiters that are designed to protect the wearer’s body including head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes with comparable risks. For the protection of the wearer’s head and feet, this International Standard is only applicable to hoods and gaiters. This International Standard does not cover requirements for feet, hand, face, and/or eye protectors.

This type of protective clothing is intended to protect the wearer against spatter (small splashes of molten metal), short contact time with flame, radiant heat from an electric arc used for welding and allied processes, and minimizes the possibility of electrical shock by short-term, accidental contact with live electrical conductors at voltages up to approximately 100 V d. c. in normal conditions of welding. Sweat, soiling, or other contaminants can affect the level of protection provided against short-term accidental contact with live electric conductors at these voltages.

For adequate overall protection against the risks to which welders are likely to be exposed, personal protective equipment (PPE) covered by other International Standards should additionally be worn to protect the head, face, hands, and feet.

EN 11612

Protective clothing — Clothing to protect against heat and flame — Minimum performance requirements

ISO 11612:2015 specifies performance requirements for protective clothing made from flexible materials, which are designed to protect the wearer’s body, except the hands, from heat and/or flame. For protection of the wearer’s head and feet, the only items of protective clothing falling within the scope of ISO 11612:2015 are gaiters, hoods, and overboots. However, concerning hoods, requirements for visors and respiratory equipment are not given.

The performance requirements set out in ISO 11612:2015 are applicable to protective clothing which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.
