This standard is equivalent to 1509312:1990 electric positive welding equipment for electrode stop shrinkage pin, this standard is a section of the development, need to explain the full: ISO 15578-1995 electric welding machine safety requirements "put forward a higher requirement on the insulation resistance of the welding machine, ISO 9312 Article 5 stipulates that the material of the insulating pin PHCCI (phenolic layer bottom cloth) is no longer applicable: Therefore, wood The standard stipulates that the manufacturing material of the pen edge should be EPGCI (epoxy glass cloth laminate), the corresponding national standard code is GB/1303.1, and its electrical and mechanical properties are much better than PHCC1. This standard is proposed and approved by the National Electric Welding Machine Standardization Technical Committee. The drafting unit of this standard is Chengdu Electric Welding Machine Factory, and the main initiator of this standard is Zhang Longzu.

Is0 Foreword
The International Organization for Standardization (ISO) and the International Standardization Bodies (ISU Groups) are a worldwide association of national standardization bodies. The development of international standards is usually carried out through technical committees of ISO. Member bodies interested in a particular field of expertise have the right to participate in the committee: the international organizations that network with ISO4 and those that do not are also responsible for this work. They work closely with the International Electrotechnical Committee (FF) in the field of electrotechnical standardization. Draft international standards adopted by the committees are circulated to the member bodies for voting. When they are published as national standards, at least one member body is required to vote on the standards.
International Standard IS09312:1990 was developed by SU/TC44 "Welding and Similar Technical Committees", and the Machinery Industry Standard of the People's Republic of China
