Non-destructive testing - Materials for magnetic particle
testing
1 Scope
This document specifies the classification, technical requirements and inspection
methods for materials for magnetic particle testing (or testing medium, including
magnetic suspension, dry magnetic particle, carrier liquid, contrast enhancer).
This Standard applies to type inspection and batch inspection of testing medium.
This Standard can also be used as the basis for acceptance of user orders.
2 Normative references
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For dated references, the subsequent amendments (excluding
corrigendum) or revisions do not apply to this Standard, however, parties who reach an
agreement based on this Standard are encouraged to study if the latest versions of these
documents are applicable. For undated references, the latest edition of the referenced
document applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 12604.5
apply.
4 Safety precautions
Materials for magnetic particle testing and chemicals used for their testing may be
hazardous, flammable and/or volatile. It is therefore advisable to observe the prescribed
precautions. All national and local regulations on safety, health and environmental
protection requirements shall be followed.
5 Classification
5.1 Overview
Magnetic particle testing materials covered by this Standard shall be classified as
follows.
5.2 Magnetic suspension
The magnetic suspension shall be composed of colored magnetic particle or fluorescent
magnetic particle and a suitable carrier liquid. It shall be in a uniform suspension when
stirring.
Magnetic suspension can be prepared from the purchased concentrated products
(including magnetic paste and dry magnetic particle) or can be used directly.
5.3 Dry magnetic particle
The dry magnetic particle used in the dry method shall be subdivided into color and/or
fluorescent magnetic particle.
6 Inspection rules
6.1 Batching rules
Each batch consists of a number of magnetic particle material products with the same
properties, and all marked with a specific symbol that is put into production at one time.
6.2 Inspection classification
6.2.1 Type inspection
Type inspection shall be carried out in one of the following situations.
a) When resuming production after new production, conversion or suspension of
production;
b) When materials or workmanship change;
c) When the contract stipulates;
d) When it has been more than six months since the last type inspection.
The type inspection of magnetic particle materials shall be carried out in accordance
with the requirements of GB/f 15822.Type inspection is carried out to demonstrate the
suitability of the product for the intended use. This inspection shall be performed by an
independent laboratory1.
The independent laboratory shall issue an inspection report for the implementation of
this Standard.
6.2.2 Batch inspection (or exit-factory inspection)
The batch inspection required by this Standard shall be carried out in accordance with
the requirements of GB/T 15822 for each batch of products. Batch inspection is
performed to demonstrate the consistency of the batch characteristics with the approved
type-inspected products.
If agreed at the time of ordering, the manufacturer or supplier of the magnetic particle
testing material shall provide an inspection certificate, so as to indicate which methods
have been used in accordance with this Standard. The certificate shall include the results
obtained and the tolerances allowed.
1 An independent laboratory is a professional organization that is certified or entrusted by the relevant competent
authority, and understands and is familiar with the magnetic particle testing process. The list of qualified
independent laboratories can be obtained from the Secretariat of...
