Scope
Main technical content: This standard includes eight chapters and two appendices: 1. Preface 2. Normative reference documents 3. Overview 4. Metrological characteristics 5. Calibration conditions 6. Calibration items and methods 7. Processing of calibration results 8. Calibration intervals Appendix A: Recording format of vacuum water absorption testers Appendix B: Uncertainty of measurement results of vacuum water absorption testers This standard references relevant content from related national standards, industry standards, and metrological technical documents, including JJF 1001《General Metrological Terms and Definitions》, JJF 1059.1《Evaluation and Expression of Measurement Uncertainty》, and GB/T 3810.3-2016《Test Methods for Ceramic Tiles》。 This standard clarifies the scope of application and usage conditions, and sets clear requirements for the metrology and technical specifications of vacuum water absorption testers. It also details the test conditions and methods for various test items, ensuring that the above content is more scientific and standardized for use by technical institutions across the country. A model ZF-2 waterproof membrane vacuum water absorption tester was calibrated according to this method, and all parameters were successfully calibrated in accordance with the requirements of this calibration method, with no discrepancies found. Based on this method, calibration of vacuum water absorption testers can be completed smoothly.
