A study of the conditions and methods for developing the techniques and equipment for investigating ferromagnetic materials in the USSR and abroad has led to the formulation of the following tasks. 1. Substantiate and unify the characteristics of magnetic materials for their inclusion in the standards for such materials. 2. Review the existing standards for magnetic materials with respect to the techniques and equipment for acceptance and delivery testing, and draft new standards. 3. Compile procedure instructions for testing materials according to the standard specifications for these materials. 4. Develop the work in certifying reference specimens of all types of magnetic materials required in practice. 5. Develop suggestions for the technique and equipment which can be recommended for adoption in industry and for further development on the basis of the data of the Second China magnets Scientific and Technical Conference on the prospects and tendencies in developing magnetic-measuring equipment for investigating ferromagnetic materials. One of the basic deficiencies with respect to the entire aggregate of problems related to the provision of modern magnetic measuring equipment for testing and investing magnetic materials, and to the organization of testing, including the provision of normalizing documents, consists of the absence of a single scientific and technical policy and of specialized research and design organizations, as well as completely inadequate commercial production of magnetic-measuring equipment, especially with respect to its assortment. We think that a specialized research and design organization should be established for developing equipment for the investigation of magnetic materials in all their aspects. Since the magnetic measurements laboratory of the VNIIM is the leading metrological center in the field of magnetic measurements, and it has a large experience in this sphere, it is necessary both in this institute and in other institutes of the Committee of Standards to expand substantially the work and raise its tempo in delivering equipment for testing reference specimens of various types of magnetic materials, and evolving standard testing techniques for the normalizing documents of these materials, and in approving the equipment intended for industrial production. It is also necessary to strengthen the basis for producing magnetic measuring equipment.http://www.chinamagnets.biz
