The standard of pop up sink waste salt spray test

- May 04, 2018 -

The salt spray test standard is a specific and specific requirement for the salt spray test conditions, such as temperature, humidity, concentration of sodium chloride solution and PH value, and also provides technical requirements for the performance of the salt spray test chamber. Which salt spray test standard for the same pop up sink waste should be selected based on the characteristics of the salt spray test and the metal corrosion rate and sensitivity to salt spray. The following describes several salt spray test standards, such as GB/T2423.17-1993 "Electrical and electronic products basic environmental testing procedures test Ka: salt spray test method", GB/T2423.18-2000 "electrical and electronic products environmental test part 2 : Test test Kb: salt spray, alternating (sodium chloride solution), GB 5938-86 "Corrosion Resistance Test Method for Metal Coatings and Chemical Treatment Layers of Light Industrial Products", GB/T 1771-91 "Stain Resistance of Paints and Varnishes Determination of salt spray performance."

The purpose of the salt spray test is to evaluate the salt spray corrosion resistance of pop up sink waste. The salt spray test result is the judgement of pop up sink waste quality. Its judgment result is correct and reasonable. It is a correct measure of pop up sink waste salt spray resistance. The key to corrosion quality. Salt spray test results are judged by methods such as: rating determination method, weighing determination method, corrosive appearance determination method, and corrosion data statistical analysis method. The rating judgment method divides the percentage of the ratio of the erosion area to the total area into several levels according to a certain method. A certain level is used as a criterion for the determination of conformity. It is suitable for flat plate pop up sink waste samples for evaluation. The weighing determination method passes through before and after the corrosion test. The weight of the pop up sink waste sample is weighed, and the weight lost from the corrosion is calculated to evaluate the quality of the corrosion resistance of the sample. It is particularly suitable for assessing the corrosion resistance of a certain metal; the corrosion occurrence determination method is a qualitative determination. The method, which is based on the salt spray corrosion test, determines whether the product is corroded to determine the sample. Most of the general pop up sink waste standards use this method. The corrosion data statistical analysis method provides confidence in the design of corrosion tests, analysis of corrosion data, and determination of corrosion data. Degree method, it is mainly used for analysis and statistics of corrosion, not for the specific quality determination of a specific pop up sink waste.
