ISA 60079-15 (12.12.02)-2012 PDF Download

The ISA 60079-15 (12.12.02)-2012 standard sets forth specific criteria for the design, testing, and labeling of electrical equipment that is intended for use in areas with explosive gas atmospheres. The standard focuses on equipment that falls into Group II, which includes atmospheres containing various types of flammable gases, vapors, or mists.

The standard specifically addresses equipment that utilizes type of protection "n". This type of protection is suitable for use in atmospheres where the risk of ignition is relatively low. It is important to note that this standard is applicable to electrical equipment with a rated voltage not exceeding 15 kV root mean square (r.m.s.) for both alternating current (a.c.) and direct current (d.c.) systems.

By providing guidelines for construction, testing, and marking, this standard aims to ensure that electrical equipment with type of protection "n" meets the necessary safety requirements to prevent the ignition of explosive gases. Compliance with this standard is crucial in maintaining a safe working environment in industries where explosive atmospheres may be present.
