Coating classifications for metal product - Technical
conditions
1 Scope
This standard specifies the requirements for classification, application scope,
technical requirements, acceptance rules, inspection method, markings of the
electroplating of medical equipment.
This standard is applicable to the single-layer (nickel, chromium, zinc, tin, silver,
gold, cadmium, black nickel) plating and multi-layer (nickel + chromium, nickel
+ nickel + chromium, copper + nickel + chromium, copper-tin alloy + chromium)
plating of the metal articles for protective decoration purpose.
2 Normative references
GB 1031 Surface roughness - Parameters and their values
GB 1238 Designation symbols for metal coatings and chemical treatments
GB 6463 Metallic and other non-organic coatings - Review of methods of
measurement of thickness
3 Classification of plating
3.1 According to the working conditions and structural requirements of metal
parts, the plating is divided into the following 6 categories.
3.2 The scope of application of plating in various medical equipment is as
shown in Table 1.
4 Technical requirements for plating
4.1 The minimum thickness of various plating of finished parts are as specified
in Table 2.
4.2 The metal parts are divided into bright or matt plating according to needs.
According to the requirements in GB 1238, the bright plating includes full bright
(L3), bright (L2), semi-bright (L1) plating. The matt plating is dark plating.
4.3 The grading requirements for various plating's appearance shall be as
specified in Table 4 ~ 12.
4.3.1 The grading requirements for chromium-plating's appearance are as
shown in Table 4.
4.3.5 Grading requirements for the appearance of zinc plating and cadmium
plating are as specified in Table 8.
4.3.7 Grading requirements for the appearance of tin plating are as specified in
Table 10.
4.3.8 Grading requirements for the appearance of black nickel plating are as
specified in Table 11.
5 Acceptance rules, inspection methods, marking
5.1 The plating of the parts is in the unit of piece. The inspection department of
the manufacturer will inspect it.
5.2 Inspection of plating appearance. For large parts, it shall be inspected one
by one; for small parts, sample more than 3% from each batch for inspection.
5.4 The marking of the plating shall be carried out in accordance with the
provisions of GB 1238, that is, the representation of the metal plating is
composed of three parts, each part is connected to other part by the dot "•".
The order of arrangement is as follows.
5.5 For parts which need plating, it shall be marked according to the provisions
of GB 1238 in the design drawings and other design documents.
Example 1.For the electroplating category V nickel + chromium plating; full
bright; grade 1 appearance, Ra0.20 µm, the marking, appearance grade and Ra
are represented as follows.
