Foreword
This Standard replaces GB/T 13560-2000 "Materials for sintered neodymium iron
boron permanent magnets".
Compared with GB/T 13560-2000, the major changes of this Standard are as follows.
— ADD "GB/T 17951 Standard specification for magnetically hard materials" in
reference standard;
— ADD material grades;
— ADJUST parameters of parts of material grades.
Annex A of this Standard is normative; Annex B and Annex C are informative.
This Standard was proposed and shall be under the jurisdiction of the National
Standardization Technical Committee on Rare Earth.
This Standard was responsibly drafted by the Baotou Rare Earth Research Institute.
Main drafters of this Standard. Liu Guozheng, Zhao Zengqi, Zhao Ruijin, Zhao
Mingjing, Wang Biao, Gao Lan.
Previous editions replaced by this Standard are as follows.

Materials for sintered neodymium iron boron permanent
magnets
1 Scope
This Standard specifies the requirements, test methods, inspection rules and marks,
packaging, transportation, and storage of materials for sintered neodymium iron boron
permanent magnets.
This Standard applies to the materials for sintered neodymium iron boron permanent
magnets that are produced by powder metallurgy process. It is provided for
electronics, electrical, mechanical, medical device fields, etc. to manufacture
permanent magnet devices.

3 Terms and definitions
Terms and definitions established in GB/T 9637 AND the following terms and
definitions apply to this Standard.
3.1
Principal magnetic properties
048061 NdFeB 220/278 1.05 2786 756 207~239
5 Test methods
5.1 Test methods of principal magnetic properties of products shall be conducted
according to the specifications of GB/T 3217.
5.2 Product dimension and geometric deviation shall be tested by using measuring
tools that meet the accuracy requirements and comply with the national measurement
standards, or special measuring tools that are confirmed by both supplying and
purchasing parties.
5.3 Surface quality of products shall be inspected visually.
5.4 Rounding-off of numerical values is conducted according to the specifications of
GB/T 8170.
6 Inspection rules
6.1 Inspection and acceptance
6.1.1 Products are inspected by the supplier's quality and technical supervision
departments, to ensure that products comply with the specifications of this Standard.
And fill in the quality certificate.
6.1.2 Purchasing party shall inspect the received products according to the
specification of this Standard. When the test results are inconsistent with the
specifications of this Standard, it shall inform supplying party within two months from
the date of receipt of the products; then handle by both supplying and purchasing
parties through consultation. If necessary, it can entrust an organization recognized by
both parties to conduct arbitration, and sampling mutually at purchasing party’s site.
6.2 Batch
Each batch of products shall consist of the products of the same-grade, the
same-production process, and the same-specification.
6.3 Test items
Each batch of products shall be conducted for inspection of principal magnetic
properties, dimension deviation, geometric deviation, and surface quality.
6.4 Sampling
Sampling quantity of products shall be in accordance with the specifications of GB/T
2828.1. Qualification level of the principal magnetic properties of products is 1.5-grade
of special inspection level S2; inspection qualification level of other items is 1.5-grade
of inspection level ll.
6.5 Determination of test results
If the test result of any item is unqualified, then select double quantity of samples from
this batch of products, and re-inspect the unqualified item. If it is still unqualified, then
this batch of products are determined as unqualified.
7 Marks, packaging, transportation, and storage
7.1 Marks and packaging
7.1.1 Labels shall be attached to each packaging cases (boxes) and indicate.
supplier's name, product name, grade, specification and dimension, batch number,
quantity, net weight, and date of manufacture. Products are generally delivered at
magnetically neutral state. If purchasing party require magnetization and it is specified
in the contract, the products can be magnetized before delivery. For the products of
which the orientation direction is not easy to identify, it shall indicate the magnetization
direction.
7.1.2 Products shall be packaged with cases (boxes), so as to ensure no damage
during transportation and storage. Packaging requirements of magnetized material
shall comply with the corresponding specifications of the corresponding mode of
transportation and storage.
7.2 Transportation and storage
Products shall be handled with care in transit; and stored in a well-ventilated, dry,
non-corrosive-atmosphere place.
7.3 Quality certificate
Each batch of products shall be accompanied with quality certificate, indicating.
a) supplier's name;
b) product name, grade, specification and dimension;
c) batch number;
d) net weight and quantity;
e) the inspection results of each item, marks of supplier's quality and technical
supervision department;
mechanical, medical device fields, etc.. For example. application in
permanent-magnetic motors, speakers, magnetic separator, computer disk drives,
magnetic resonance imaging equipment, instruments, and so on.
