aRC fLASH STANDARDS

40 Cal Arc Flash Protection Kit complies to the following standards:

EN ISO 11612
IEC 61482-2
EN 1149-5

Arc Flash Standards

The range of arc flash protection suits and kits addresses the requirements for clothing that protects from the thermal hazards of electric arcs according to applicable international standards.

The performance of clothing to protect from electrical arcs may be qualified using two test methods, depending on the zone of influence :

IEC 61482-2 : GENERAL REQUIREMENTS

Test Methods

IEC 61481-2
Open arc method

Determination of the ATPV rating of clothing stated in calories/cm² (American principle)

IEC 61482-1-2
Box test method

Determination of the protection class of the clothing depending on the level of intensity of the electrical installation, according to two classes:
Class 1 (4 kA during 0,5 s at 30 cm)
Class 2 (7 kA during 0.5 s at 30 cm)
(European principle)

arc flash hazard categories

In the USA, the national fire protection association (NFPA) uses four categories to classify the arc flash risk. The principle of categories is the method used in NFPA 70E to inform users about the protection they need while working on or near live equipment. The aim is to be protected from the risk of second-degree burns.
