Mailing address: 024 005 District of Chifeng City, the western part of the whole Downing Street. Received :2009-08-25 measurement of food and strong demand for iron and steel industry news recently from the National Institute of Metrology measurement science and technology needs of key industries research project team was informed that, in the hospital a few days ago, organized by the food, iron and steel industry, research and measurement needs forum, experts and enterprises proposes strengthening the rapid detection of food products online, online detection of iron and steel products a number of measuring the level of science and technology needs. They hope the Chinese Metrology Institute for the future development of the two industries provide more technical support. research group in Shandong and Jiangxi provinces in some key food businesses understand the process of research, the current food enterprises widespread lack of efficiency of product testing, quality standards and inspection and monitoring technology detection technology lagged behind. food companies are eager to strengthen the Institute of Metrology rapid detection of food products online research technology and testing methods; research and development of new, such as feed, honey and Biological product quality control and testing techniques; assist in the development of food additives containing complex product testing standards. Jiangxi Province Product Quality Supervision and Inspection Institute raised the standard material supply cycle length, the standard method of updating is not timely, the old part of the standard does not apply to new there a lack of standards for food safety issues and other issues; Shandong provincial quality inspection center of the Institute of Metrology hope to help solve, such as juice content of the test deployment, test standard materials, such as testing of new varieties developed technical problems. iron and steel industry is the pillar industry of national economy in economic construction, social development, national defense,ugg boots günstig, and played an important role. Institute of Metrology Organization in the forum,ugg prezzo, the experts described in detail in the steel industry process monitoring and quality control, measurement needs, particularly In the high-quality, high value-added products in the production of the relevant requirements of online testing, such as rolling force detection, detection of shape and geometry, the opening degree detection,ugg boots billig, NDT inspection, chemical composition and continuous detection of temperature, pressure testing, the residual stress testing. from the National Centre for Iron and Steel materials testing experts Test method combining metal and steel industries to international standards, raised the standard steel industry based on the measurement of the urgent needs of areas, such as strong values (20MN above) and small force value, the Leeb hardness, nano-indentation hardness,ugg stivali, pendulum impact machine traceability standards and stability of K-type thermocouple, and on the traceability of the problems in the steel industry and the traceability of money requirements and other content of the topic.
