Introduction

The National Metrology Technical Specification "Calibration Specification for Lubricating Oil Foam Characteristic Tester" (Standard Number: JJF(石化)054-2021), published on December 2, 2021 and officially implemented from April 1, 2022, sets forth the requirements and procedures necessary for the calibration of instruments designed to measure the foam characteristics of lubricating oils. This standard aims to ensure that test results are accurate and consistent across different testing environments by providing detailed guidelines on the operational parameters, measurement uncertainties, and environmental conditions required during the calibration process.

The specification covers various aspects including but not limited to the instrument's design features, performance criteria, and procedures for both initial verification and periodic checks. It also outlines specific test methods to assess the accuracy of foam formation time and foam stability under varying temperature conditions relevant to the operational parameters of lubricating oils.
