3 Terms and definitions
The terms and definitions, as defined in GB/T 10123, as well as the following
terms and definitions, apply to this document.
3.1
Reference material
Materials with known test performance.
3.2
Reference specimen
Part of the reference material (3.1), which is to check the reproducibility
and repeatability of the test results of the test chamber used.
4 Principle
The neutral salt spray test (NSS) is a test method, for atomizing a 5%
sodium chloride neutral solution, in a controlled environment.
The acetic acid salt spray test (AASS) is a test method, in which a 5%
sodium chloride acid solution, added with glacial acetic acid, is atomized, in a
controlled environment.
5 Test solution
At a temperature of 25 °C ± 2 °C, dissolve sodium chloride in distilled
water or deionized water, which has a conductivity of not higher than 20 µS/cm,
to prepare a solution, which has a concentration of 50 g/L ± 5 g/L.
6 Test equipment
All components, which are in contact with salt spray or test solution, shall
be made of corrosion-resistant materials, which do not affect the corrosiveness
of the solution.
The spray in the chamber shall be evenly distributed. For the chambers,
which have a capacity of less than 0.4 m3, due to the capacity restriction, it shall
carefully consider the effect of the loading of the chamber on the spray
distribution and temperature.
7 Methods of evaluating the performance of salt spray chamber
A steel reference specimen shall be used, to determine the corrosivity of the test.
As a supplement to the steel reference specimen, the high-purity zinc
reference specimen can be tested; the corrosion performance can be
determined, with reference to the provisions of Appendix D.
8 Test specimen
The type, quantity, shape, size of the test specimen shall be selected,
according to the relevant specifications of the tested material or product.
If the test specimen is cut from a workpiece, which has a covering layer, it
shall not damage the covering layer near the cutting area.
9 Placement of test specimens
The test specimen shall not be placed, where the salt mist is directly sprayed.
The test specimen holder shall be made of inert non-metallic materials.
10 Test conditions
Due to the different performance of the empty and fully loaded test
chambers, check the salt spray sedimentation rate and other test conditions of
the test chamber, with a similar loading volume, during the test.
11 Test period
The test period shall be selected, according to the relevant standards of
the tested material or product. If there is no standard, it can be negotiated and
agreed by related parties. The recommended test cycle is 2 h, 6 h, 24 h, 48 h,
96 h, 168 h, 240 h, 480 h, 720 h, 1008 h.
12 Handling of test specimens after the test
How to handle the test specimen, after the test, shall be included in the test
specification or material specification, which is provided by the customer.
13 Evaluation of test results
The appropriate evaluation standard for the tested coating or product shall be
determined in good engineering practice.
14 Test report
The test report shall state the test results, in accordance with the result
evaluation criteria.
