With industrial equipment for North America, the equipment user is obligated to utilize equipment which conforms to 29 CFR 1910 of the Industrial Safety and Health Law. We reference required items of NFPA 70 and UL508A, focusing on NFPA 79 for the electrical safety standards for industrial equipment which is listed. Furthermore, we reference ANSI, ASME, UL, and other North American standards in accordance with the details of the equipment
NFPA70 is a US electrical work standard stipulated by NFPA (National Fire Protection Associations). It is also called an NEC (National Electrical Code) and aims to protect people or property from dangers caused by using electricity.
NFPA79 (Electrical standard for industrial machinery) stipulates details relating to electric shock and fire safety protection for industrial machinery electrical devices in the US relating to NEC. It is adapted to electrical/electronic facilities and equipment or industrial equipment and facilities and power supply parts relating to the electrical equipment of machines that operate at 600V or a nominal voltage below that.
UL508A is a standard formulated by UL. This standard differs to national standards in that it is an NFPA79 reference standard, so UL508A must be followed regarding industrial control panel design for the North American market.
ANSI is an abbreviation of American National Standards Institute. This institute standardizes and approves industrial standards in the US, which are called ANSI standards. ANSI standards may also serve as an ISO/IEC standard.
ASME is an abbreviation of American Society of Mechanical Engineers. This society’s activities include standardization work mainly in the field of mechanical engineering and certification based on such standards.
Standards produced by UL are called UL standards, which are often seen as a national standard by the ANSI. UL standards are recognized as America’s representative product safety standards.
Field Evaluation (Field Labeling) is a certification system operated by the AHJ (Authority Having Jurisdiction) in each state and city, and the required contents vary for each region. When the equipment conforms to the evaluations, testing, and on-site observations conducted through the cooperation of partner companies in the country or on location in North America, a Field Label is affixed to the equipment and it is approved for operation.
On-site site testing or Test site testing and measure consultation
Part 15 established by the FCC (Federal Communications Commission) covers radio-frequency devices (information devices), while Part 19 covers equipment for industrial, scientific, and medical use. Testing and verification of the equipment must be conducted, or certification obtained from the FCC itself. The testing measures the noise generated from the equipment.
As required by the FDA (Food and Drug Administration), for equipment containing lasers, it is necessary to apply to authorities to verify that the requirements of 21 CFR 1040.10 of the Industrial Safety and Health Law or IEC 60825-1 have been met.
