Communications

FCC Marking (U.S.) This certifies that the electromagnetic interference (EMI) from the device is under limits approved by the Federal Communications Commission (FCC). The FCC marking is for any product that can emit more than 9 kHz. These can include power adapters, IT equipment, Bluetooth devices, wireless local area networking equipment, remote control transmitters, and other devices. These are tested to see if they may cause interference with other equipment.

Fire & Life Safety

ATEX Zone-2/22 approval certificate (EU) This classification for Zone 2 refers to safety in settings such as a chemical or petrochemical plant where there is a larger risk of explosion during routine operations. Zone 22 refers to settings where dust is a factor in combustion, such as food processing plants, where powdered food substances that are easily ground may ignite more easily. The standard qualifies that an explosion is not likely to occur for equipment under this designation but, if it does, it will be for a short period of time only.

IP65/66 NEMA (International) Ingress Protection (IP) ratings are displayed as a two-digit number. The first digit reflects the level of protection against dust; the second digit reflects the level of protection against liquids. IP65 refers to sealing effectiveness levels provided by an electrical enclosure that are “dust tight” and protected against water projected from a nozzle.

NFPA (72 (U.S.) UL 864 This specification is related to threat notifications for events such as fire, weather emergencies, terrorist events, biological, chemical, and nuclear emergencies, among others. The UL 864 standard was initially established to be the “Standard for Control Units and Accessories for Fire Alarm Systems”, but today generally follows changes in National Fire Protection Association (NFPA) 72. Chapters within NFPA 72 relevant to UL 864 cover a variety of fire safety aspects, and greatly influence fire safety product design relating to aspects like system alarm response time, notification types (visible and audible notifications), interconnected device compatibility, software integrity, and others.

UL/cUL 508/UL 61010 (Equivalent to IEC 61010) (US & Canada) UL 61010 is a series of safety criteria for industrial controls such as test and measurement, laboratory, and process control equipment of 1500 volts or less used to start, stop, regulate, control, or protect electric motors. Performance requirements are based on hazards one could encounter while using the product, such as electric shock and burn, mechanical hazards, effects of mechanical stresses, fluid pressure and radiation, excessive temperature, and spread of fire from the equipment. This certification is determined by inspection, type tests, routine tests, and risk assessment.

UL/cUL 60601 Medical Compliance (U.S. & Canada, equivalent to IEC 60601 in Europe) This certification refers to general requirements for safety for medical electrical equipment. It provides detailed requirements for medical device labeling for the user related to safe installation, use, storage, servicing, and maintenance. It requires that product instruction explains safety-critical information such as electrical use that may not be otherwise obvious. This standard pertains to product labeling, including durability of markings, accompanying documents, instructions for use, instructions for cleaning, sterilization, and maintenance, environmental information, replacement parts information and circuit diagrams, and transportation and storage information.

MIL-STD-901-D Shock (U.S.) This U.S. government military specification (also called a “MilSpec”) seeks to prevent high-impact mechanical shock damage to equipment mounted on ships. It helps evaluate whether equipment mounted in a ship will survive a conflict scenario where large transient shocks are created generated by collisions or explosions. This standard confirms that essential equipment can shut down as a result of an initial shock but is able to automatically restart without any repairs. The standard also specifies that non-essential equipment can fail in a shock event but does not create a hazard to onboard personnel or other, essential equipment.
