Purpose meaning
The platinum resistance thermometer is one of the most important commonly used temperature measuring instruments at home and abroad, and it is also a standard instrument that is commonly used in the world as a temperature scale of 13.8333K~961.78°C. It has played an important role in ensuring the consistency and accuracy of international temperature values. Pure platinum wire is currently the most important resistance thermometer material. Due to its high melting point, it has good chemical stability and excellent oxidation resistance at high temperatures. Its high resistivity, good plasticity, and easy access to high-purity filaments have long been used to make platinum resistance thermometers. According to the use conditions and technical requirements, thermometers are often divided into standard platinum resistance thermometers and industrial platinum resistance thermometers. The standard platinum resistance thermometer is mainly used in the laboratory to transfer the international practical temperature scale (ITS-90) and precision temperature measurement; the industrial platinum resistance thermometer is mainly used to produce the temperature measured from -200°C~850°C. The structure of the two resistance elements is different, and the platinum wire used is different. The standard platinum resistance thermometer is the most precise and stable thermometer. Due to the presence of impurities and the presence of defects in any trace amount, the performance and instability of the platinum can be caused. The platinum wire used for the production of standard platinum resistance thermometers must be of the highest purity and not only chemical properties, but also the physical properties, temperature coefficient of resistance, and resistance ratio should be strictly stipulated. In 1986, China issued two national standards, namely the platinum wire for GB 5977-86 resistance thermometers and the platinum wire resistance ratio test method for GB 5978-86 resistance thermometers. In 1999, it was revised to GB/T 5977-1999 "Platinum wire for resistance thermometers". This standard has played an important role in the transmission of temperature standards in China and the development of industrial temperature measurement technology. Since the implementation of this standard, it has been 15 years since then. With the continuous development of China's industrial industry, the application range of platinum wire for resistance thermometers has been continuously expanding and the technical performance has been continuously improved. In order to meet the needs of the development of science and technology in China, it is urgent to revisit the national standard.
Domestic and foreign situation
In order to ensure the accuracy of the international temperature scale, and reproduce the same temperature scale with high accuracy to ensure the unity and accuracy of international temperature values, our institute completed the ITPS-68 temperature scale instrument as early as the 1980s. Standardization work has led to the formulation of national standards. The implementation of this standard has played a considerable role in the transmission of temperature standards in China and the development of industrial temperature measurement technology for many years. According to the resolutions of the 18th International Conference on Metrology (CGPM) and the 77th International Metrological Committee (CIPM), the "International Temperature Scale of 1990 (ITS-90)" was implemented worldwide as of January 1, 1990. “International Practical Temperature Scale (IPTS-68) in 1968” and “Temperature Temperature Scale of 0.5-30K (EPT-76) in 1976”. In the ITS-90 international temperature standard, the definition of the standard thermometer resistance ratio W has changed, and the control value of the thermometer resistance ratio has also changed. IEC 60751 "Industrial Platinum Resistance Thermometers and Platinum Temperature Sensors" was developed in 1983 and revised in 1986, 1995 and 2008 respectively. The national standard “Platinum Wire for Resistance Thermometers”, which is the key material for its support, should be revised as soon as possible to achieve convergence and harmonization with international standards.
Note
According to the national review of the national standards of the National Instruments Functional Materials Standardization Technical Committee (SAC/TC419) 2014, the revised plan for the national standard was proposed in 2014. The plan was approved by the Standards Committee at its annual meeting in 2014. Belongs to Work Point 12 "New Materials"

Purpose meaning
GB/T24925 has been released since 2009 and has been for 5 years. The formulation of the standard is based on the original machinery industry standard JB/T7749-1995 "Technical conditions of cryogenic valves", based on the principle of inheritance of standards, the continuation of some terms. At that time, the international standards for cryogenic valves had not yet been introduced. This standard was limited by the prevailing conditions. The content of the test requirements and other aspects formulated were incompatible with the domestic production reality and the international standards that were issued in 2013, especially at present. The rapid development of low temperature engineering technology. The quality of cryogenic valves determines whether low temperature engineering can be safely, economically, and continuously produced, and determines the process of localization of cryogenic valves. Therefore, it is necessary to revise the product standard GB/T24925-2010 for cryogenic valves. In order to facilitate the international practice, effectively guide the design, manufacture, testing and acceptance of cryogenic valve products.

Technical content
This standard was limited by the prevailing conditions. The content of the test requirements and other aspects formulated did not meet the domestic production reality and the international standards issued in 2013, especially with the rapid development of low-temperature engineering technology. The quality of cryogenic valves determines whether low temperature engineering can be safely, economically, and continuously produced, and determines the process of localization of cryogenic valves. Therefore, it is necessary to revise the product standard GB/T24925-2010 for cryogenic valves. In order to facilitate the international practice, effectively guide the design, manufacture, testing and acceptance of cryogenic valve products.
Domestic and foreign situation
After retrieval, the relevant foreign standards are as follows: 1, BS6364: 1989 "Cryogenic Valve" Only the British system size. Due to many years of unrevised, many of the provisions are not suitable for the needs of the development of low-temperature industries. 2. MSS SP-134-2006 “Requirements for cryogenic valves and their body/bonnet extensions” is mainly aimed at the extended part of cryogenic valves and is not a product standard. 3, DIN EN1626-1999 "Cryogenic vessel valve for cryogenic vessels" has a narrow range of applications. 4, MESC SPE 77/200-2008 "Cryogenic and cryogenic valves" are available in inch sizes only. It is not widely used on a global scale and few domestic companies have adopted it. 5. ISO-28921-1-2013 Industrial Valves—Cryogenic Isolation Valves Part 1 Design, manufacturing, and product testing are the new standards issued by the ISO International Organization for Standardization in 2013. The range covers imperial, metric cryogenic valves. 6, domestic GB/T24925-2010 cryogenic valve technology conditions
