In 6.2, the test methods of temperature coefficient of remanence and intrinsic coercivity of materials are subject to the requirements of GB/T 24270 (see 6.2); —Dimensional deviations in Table A.1 of Annex A are modified (see Table A.1); —Annex B is modified as follows: Table B.1 is split into Table B.1 "Additional magnetic properties of sintered neodymium iron boron permanent magnets" and Table B.2 "Mechanical and physical properties of sintered neodymium iron boron permanent magnets"; some parameters are modified and the parameters of bending strength and maximum operating temperature are added (see Table B.1 and Table B.2); —Chemical composition of sintered neodymium iron boron permanent magnets is added to Annex C (see Table C.1); —Table of the system of unit and conversion of magnetic property and table of correspondence between designation and magnetic property, for sintered neodymium iron boron permanent magnets are added to Annex D (see Table D.1 and Table D.2); This standard was proposed by and is under the jurisdiction of the National Technical Committee on Rare Earth of Standardization Administration of China (SAC/TC 229); The previous editions of the standard replaced by this standard are as follows: —GB/T 13560-1992, GB/T 13560-2000 and GB/T 13560-2009. Sintered neodymium iron boron permanent magnets 1 Scope This standard specifies the requirements, test methods, inspection rules, marking, packaging, transport, storage, quality certificate for sintered neodymium iron boron permanent magnets. This standard is applicable to sintered neodymium iron boron permanent magnets produced by powder metallurgy process. 2 Normative references The following referenced documents are indispensable for the application of this document.

It is calculated by Formula (1). (1) Where, hirr—irreversible flux losses, %; Ф(T0)—flux of magnet at temperature T0 under initial open-circuit conditions (Wb); Ф(T1)—open-cirtuit flux of magnet with temperature changing from T0 to T1 and then reversing to T0 (Wb). 3.4 maximum operating temperature The maximum holding temperature of a cylindrical sample of permanent magnet (with a diameter of D and a height of L, and L/D=0.7) in thermal demagnetization state, which, after saturation magnetization, is heated from room temperature to a certain constant temperature and, after 2 hours holding period, is then cooled to room temperature, with open irreversible flux losses not greater than 5%. 4 Classification and designation of material 4.1 Classification Sintered neodymium iron boron permanent magnets, by the size of intrinsic coercivity, are classified into seven types—low coercivity N, medium coercivity M, high coercivity H, extra high coercivity SH, super high coercivity UH, extreme high EH and ultra high TH. 4.2 Designation Each type, by maximum magnetic energy product, are classified into several designations. Materials on each designation may be processes into permanent magnet parts of a variety of shapes and specifications, including discs, cylinders, rings and pads. 4.3 Expression of character designation Designations of sintered neodymium iron boron permanent magnets consist of the manufacturing characteristics, main description and magnetic properties of material. The first part, the letter "S", denotes the manufacturing characteristics of materials, i.e. the sintered materials produced by powder metallurgy sintering process; the second part, NdFeB, i.e. the element symbols of neodymium, iron and boron, denotes the main description of materials; the third part, the number before solidus, denotes the nominal value (kJ/m3) of maximum magnetic energy product (BH)max of sintered neodymium iron boron; the forth part, the number after solidus, denotes one tenth of the minimum intrinsic coercivity HcJ (kA/m) rounded to the nearest integer.
