Salt Spray test Chamber|Galvanized Salt Spray Test Standard

 The galvanizing salt spray test is a test method used to test the corrosion resistance of galvanized surfaces. This test method is mainly used to detect the corrosion of the surface of a test piece by exposing it to a salt spray environment under constant temperature and relative humidity conditions. Galvanized salt spray test is a common corrosion test method, which is widely used in various industries, such as construction, automotive, electronics and other fields.

Standards for Galvanizing Salt Spray Test

ASTM B117-16 Standard Practice for Operating Salt Spray (Fog) Apparatus

This standard is a standard issued by the American Society for Testing and Materials (ASTM) for testing the corrosion resistance of various materials and surface coatings. The standard specifies requirements for test equipment, test conditions, test cycles, test methods, and evaluation of test results.

ISO 9227:2017 'Corrosion tests in artificial atmospheres - Salt spray tests'

This standard is a standard issued by the International Organization for Standardization (ISO) for corrosion resistance testing of various materials and surface coatings. The standard specifies requirements for salt spray test chamber, test conditions, test cycles, test methods, and evaluation of test results.

JIS Z 2371:2015 Methods of salt spray testing for paints

This standard is a standard issued by the Japanese Industrial Standards (JIS) for testing the corrosion resistance of various materials and surface coatings. The standard specifies the requirements of salt spray test chamber, test conditions, test cycles, test methods, and evaluation of test results.

GB/T 10125-2012 Salt Spray Test Methods

This standard applies to the corrosion resistance test of various materials and surface coatings. It includes test methods for galvanized surfaces. The standard specifies the requirements of salt spray test chamber, test conditions, test cycle, test methods, test results evaluation and so on.

Implementation process of galvanizing salt spray test

Preparation of salt spray test chamber

Before the test, you need to prepare the test equipment. Test equipment: salt spray test chamber. Before the test, the equipment needs to be checked and calibrated to ensure that the equipment works properly.

Preparation of test samples

The samples to be tested are subjected to surface treatment, such as cleaning, oil removal, rust removal, etc. The samples are then placed in the test equipment. Then put the sample into the salt spray test chamber to ensure that the sample matches the test conditions.

Setting of test conditions

According to the requirements of the test standard, set the test conditions, including temperature, humidity, salt spray concentration and other parameters. The test conditions must be strictly controlled to ensure the accuracy of the test results.

Setting of test cycle

Set the test cycle according to the requirements of the test standard. The test cycle is generally 24 hours, 48 hours, 72 hours, etc., and can also be adjusted according to the actual situation.

Execution of the test

Put the sample into the salt spray test chamber, turn on the test equipment and start the test. During the test, you need to check the corrosion of the specimen regularly and record the test data.

Evaluation of test results

After the test, the corrosion of the specimen is evaluated according to the requirements of the test standard. Evaluation criteria generally include appearance inspection, corrosion assessment, etc..

Galvanized salt spray test is a common corrosion test method, widely used in various industries. The test process requires strict control of the test conditions to ensure the accuracy of the test results. Before implementing the test, it is necessary to understand the test standards and test procedures to ensure the effectiveness of the test.
