The National Metrology Technical Specification for the Calibration of Self-Heating Substance Test Instruments, designated as JJF(石化)043-2021, was published on December 2nd, 2021 and became effective from April 1st, 2022. This standard specifies procedures and requirements for calibrating instruments used in the testing of self-heating substances. These substances have a tendency to spontaneously heat under certain conditions, which poses safety risks if not properly assessed. The calibration specification aims to ensure accurate measurements are achieved by these test instruments to facilitate proper risk assessment and management.
The document outlines technical parameters such as temperature range, heating rate accuracy, and measurement uncertainty associated with the self-heating substance testing apparatus. It also provides detailed guidance on how to conduct routine calibrations, including specific calibration procedures for different components of the instrument. This standard is crucial in enhancing safety measures within industries dealing with potential self-heating materials.
Adhering to this technical specification helps maintain consistency and reliability across various laboratories conducting self-heating substance tests. It ensures that all measurements are comparable and credible, thus contributing significantly to product quality control and regulatory compliance requirements.
