ISA-82.03-1988, Safety Standard for Electrical and Electronic Test, Measuring, Controlling, and Related Equipment, covers electrical and electronic devices used to measure and control industrial processes, such as transmitters, analyzers and controllers. This standard emphasizes safe equipment operation in various environments, including indoors, outdoors or sheltered areas and handles voltages up to 250 volts. It includes rules for protecting people from electric shocks, fires and explosions, as well as requirements for building and testing equipment under normal and fault conditions. This document also explains how equipment should be marked, the types of enclosures needed to protect against weather and dust and how instructions for use and maintenance should be written. It helps companies design and test equipment with clear safety procedures that comply with international standards, supporting reliable and safe performance in different environments.
