Factory Mutual Research is an approving organization in the United States and, while businesses in many countries accept its approvals, FM approval may not be sufficient in some locales. Acceptance of FM approval will be dependent on the particular company, its location, and local regulation. The close focus (CF) and subzero (SZ) versions are not included in this approval.
A Nonincendive rating (NI) indicates that an electronic device has been tested to standards for preventing explosions in hazardous areas by limiting the ability of equipment to ignite a specified flammable gas or vapor-in-air mixture. Nonincendive equipment is incapable of releasing sufficient electrical or thermal energy to ignite flammable gases or vapors under NORMAL operation and environmental conditions. Nonincendive devices are approved for use in Class I, Division 2 locations.
