Japan National Standard Electrical Grade Performance Table
The National Standard Electrical Grade Performance Table is an essential piece of information for engineers, electricians, and DIY home improvement enthusiasts in Japan. The table sets forth the objectives and expectations for electrical safety and performance set by the Japanese Government. It serves as a tool for administrators, manufacturers, and users to evaluate and determine the grade of an electrical product or system. This article will explain the importance of the National Standard Electrical Grade Performance Table, its various components, and how to use it.
The National Standard Electrical Grade Performance Table sets forth the measures used by the Japanese government to ensure the safety and performance of electrical products and systems. The Table is based on the four categories evaluated for electrical safety and performance, namely: safety grade, grounding, insulation, and contact resistance. Within each category, the Table serves as a reference to ascertain the products grade by looking at its electrical characteristics, performance tests, and other factors.
The table is composed of six main sections, each covering different aspects of safety and performance. The sections are – Safety, Fire Hazards, Grounding, Insulation, Contact Resistance, and Maintenance. The Safety section covers the requirements that are specific to the type of equipment and its use, including the acceptable level of heat, spark and electric shock. The Fire Hazards section deals with the safety of any enclosed combustible material that may be affected by an electrical system. The Grounding section addresses the methods used to ensure the adequate grounding of an electrical system, while the Insulation section offers information on the acceptable level of insulation resistance for a particular system. Similarly, the Contact Resistance section offers guidance on the minimum level of contact resistance for a given product. Finally, the Maintenance section provides guidance on safety and maintenance procedures, such as preventive inspection of electrical products or systems.
When using the National Standard Electrical Grade Performance Table, it is important to remember that the performance criteria are based on the worst possible scenarios. This means that a system should score the minimum grade of “G” if it is to pass the test. Therefore, additional measures must be taken in order to ensure the systems electrical characteristics meet the required standards.
Additionally, the National Standard Electrical Grade Performance Table is not intended to be used as a substitute for good engineering practices. It is intended to give guidance and provide a reference point for administrators and manufacturers, as well as DIY users, to evaluate and determine the grade of a given electrical system.
The National Standard Electrical Grade Performance Table is a valuable resource, as it provides a basis for electrical safety and performance requirements, giving guidance on how to ensure the safety and reliability of electrical systems. As such, the table plays an important role in helping administrators, manufacturers and DIY users ensure their electrical products and systems are of a high quality.
