The induction motor,which converts electrical energy into mechanical energy,has been recognized as the cornerstone of industrialization.The rotor of an induction motor can be either a squirrel cage rotor or a wound-type rotor,both existing as magnetless topologies.Three-phase squirrel cage induction motors are frequently utilized in industrial drives because they are dependable,have high starting torque,are selfstarting and affordable.Single-phase induction motors,on the other hand,are commonly used for small loads such as domestic appliances in form of modest fans,pumps and electric power tools.In South Africa,there have been reports of fires and explosions resulting in live and property loss because of induction motors that have not been thoroughly tested or are incorrectly labelled in terms of ratings,electrical safety and performance.The goal of this study is targeted at preventing end-user injuries and failures caused by non-compliant induction motors,by evaluating locally manufactured/imported induction motors based on tests and evaluation from standards(IEC and SANS).The study is conducted using experimental procedures at the Explosion Prevention Technology and Rotating Machines(EPT and RM)laboratory,South African Bureau of Standards(SABS),South Africa.The main finding from the study shows differences in the nameplate characteristics of various induction motors which could have detrimental effects such as production and operational downtime in their end-use industries,at later stages. 展开更多

Airborne pa rt icle counters are used widely to test the air cleanliness of cleanrooms. The cur rent Chinese national standard of airborne particle counter calibration, GB6167 -85, Methods for Testing the Performance of Dust Particle Counter, has kept the same for more than 10 years. It is necessary to be amended in time. This paper discusses the differences between Chinese airborne particle counter calibration procedure and other new calibration procedures in other countries, and points ou t the defects of current Chinese national standard.The draft of revised Chinese National Standard is also introduced. The new revised standard, Methods for Test ing the Performance of Airborne Particle Counter, covers two level calibrations: primary and secondary. Primary calibration procedure includes testing 6 kinds of performances:sample airflow rate, false counting, particle size accuracy and re solution, particle counting stability, counting efficiency and particle concentr ation limit. Secondary calibration is a relative comparing test method to verify the counting accuracy of calibrated airborne particle counters.Finally, how to keep the calibration traceability is suggested. 展开更多

With the promulgation of the National Standard for the Teaching Quality of Undergraduate Majors in Ordinary Colleges and Universities, the state has made clear regulations on the standard for the cultivation of Chinese pharmacy talents. Based on their own actual conditions, major colleges and universities have implemented different talent training modes, including talent training modes of running talent classes, "2+1+1", "Chinese Medicine Research Practice Class", employment-oriented professional talent training mode, three-level three-type diversified talent training mode, and talent training mode oriented with adapting to the characteristics of ethnic regions. Various talent training modes have different training objectives, and corresponding training programs are formulated to meet the requirements of the National Standard for the Teaching Quality of Undergraduate Majors in Ordinary Colleges and Universities. In addition, according to the notice on Solidly Promoting Labor Education into the "National Standard for the Teaching Quality of Undergraduate Majors in Ordinary Colleges and Universities" issued by the Department of Higher Education of the Ministry of Education, the introduction of labor education to the teaching of Chinese pharmacy majors will be a trend, and Chinese pharmacy professionals are required to achieve comprehensive and coordinated development of morality, intelligence, physique, beauty, and labor. How to integrate labor education with high quality and high efficiency into the training of Chinese pharmacy professionals is a problem that major universities will think about. 展开更多

Increasing volumes of oils and fats are produced annually with a large section that are traded internationally. The International Organization for Standardization(ISO) body develops international standards covering almost all aspects of technology and manufacturing with 23,882 standards currently published. Standards in the animal and vegetable fats and oils sector is developed by Technical Committee ISO/TC 34, Food products, Subcommittee SC 11, Animal and vegetable fats and oils. Standards are developed through consensus by national members that represent ISO in their country. Each Standard is developed within a determined timeframe and goes through various pre-determined stages such as project proposal, development, national voting and commenting on the draft Standard to final publication. ISO TC34/SC11 Standards range from sampling of oils and fats, sample preparation to analysis of its composition, the minor components, and quality and identity parameters as well as contaminants. The analysis results are used by industry for product development, labelling, research and to provide peace of mind for consumers on its safety. An important future trend is the focus on the safety concerns from either environmental contamination(e.g. mineral oils) or processing contaminants such as esters of 3-MCPDs(3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol). 展开更多
