RELM Wireless’ BK Radio DPHx digital portable radio has received an intrinsically safe (IS) certification from the Factory Mutual Research Corp. This certification means the radio meets the requirements of the National Electric Code and the National Fire Protection Association for IS operations in hazardous environments in the United States and Canada, the company said. It covers Class 1 (petroleum/gas environment); Division 1 (flammable material present continuously); Group D (hazardous locations) and Group T3C (temperature rating).

However, the IS certification is valid only when the radio is used in conjunction with an IS-certified antenna and battery, according to RELM.
