Recently, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standards Committee approved the issuance of the National Standard for the Evaluation of Electromagnetic Radiation of Human Body by Lighting Equipment, which will be implemented from April 1, 2015. The standard specifies how to evaluate the electromagnetic radiation of lighting equipment and provides reference limits. The technical indicators are consistent with international standards and are applicable to indoor and outdoor buildings including industrial lighting, residential lighting, public lighting and street lighting. General lighting equipment used, etc. This standard is equivalent to the use of IEC62493:2009 "Evaluation of electromagnetic radiation for human body lighting equipment", which determines appropriate evaluation methods, standardized working conditions and measuring distances for the measurement of electromagnetic fields around the lighting equipment. The standard specifies the measurement distances for different lighting products. The introduction of the national standard "Evaluation of electromagnetic radiation of human body by lighting equipment" not only provides enterprises with an important basis for evaluating the safety of electromagnetic radiation of lighting appliances, but also provides a reference for the public to correctly understand lighting equipment, which helps to improve health and safety awareness. Eliminate public concerns. This standard has a positive effect on promoting the healthy development of China's lighting equipment industry. China is the world's largest producer and exporter of lighting equipment, but most of its products are concentrated at the low end. The introduction of this standard will prompt enterprises to improve their technology and promote trade.
In line with the continuous pursuit of technological innovation, HONGWUHUAN have developed a more economical, efficient, simple and reliable crawler type open-air drilling rig in order to adapt to the market development through long-term research and development in drilling machinery products. This product can be widely applied to rock drilling operation in open pit mining, foundation excavation, water conservancy, power station, transportation and national defense construction and other rock drilling operations. It can also drill holes for special purposes, such as anchoring holes, geological pressure measuring holes and drainage holes.
