GB/T 19870-2018

GB/T 19870-2018 specifies performance requirements, test methods, and classification criteria for industrial inspecting thermal imagers used in non-contact temperature measurement and thermal anomaly detection. It applies to handheld, fixed-mount, and portable thermal imaging devices employed in industries such as electrical power, petrochemical, metallurgy, and building diagnostics for preventive maintenance, equipment fault detection, and process monitoring. The standard ensures accuracy, reliability, and consistency of thermal imagers under defined environmental and operational conditions.
