Problems in the use of salt spray test chamber and methods and countermeasures to ensure its quality of use

As a product environmental testing equipment, especially as a testing device used by quality inspection departments for product quality inspection, in order to fully play its role, in addition to users operating and maintaining it correctly according to the manufacturer's technical requirements, it is also necessary to check and adjust its performance quality (salt spray test chamber basic reference) at regular intervals to ensure the accuracy of product salt spray testing. On the contrary, if the quality of the salt spray test chamber is poor and cannot meet the environmental requirements for product salt spray testing, it will not only waste manpower and resources, but also fail to obtain correct product corrosion resistance data, and even cause product quality judgment, bringing undue losses to the enterprise.
Measures to ensure the quality of use of salt spray test chambers
1. Vigorously carry out the implementation of the basic parameter calibration method standards for salt spray testing machines in use, and raise awareness among users of the importance of regular calibration of equipment.
In order to ensure the effectiveness of the salt spray test chamber in use and the accuracy of the product's salt spray test, the GB5170-85 standard was promulgated in 1985, which provides detailed regulations on the basic parameter calibration methods for salt spray chambers in use. Although this standard has been issued for many years, according to investigations. Many users are still unaware of this standard for building their inner cellar. Some users do not know the correct method for calibrating salt spray testing machines, and only send them for regular inspection according to the instrument measurement requirements. This approach cannot guarantee the quality of the salt spray testing machine and is prone to damage the instrument control lanthanum system. To solve this problem, some enterprises with strong technical strength should conduct regular calibration of their salt spray test chambers according to standard requirements. The technical supervision department should take advantage of their own concerns and organize standard promotion and learning classes, so that salt spray test chamber users can understand the standard method for verifying salt spray sugar content parameters. Finally, they should use their own strength to conduct regular inspections of the salt spray test chambers.
2. The technical supervision department shall carry out supervision and inspection of the quality of the use of salt spray test chambers in use.
The salt spray testing machine is an important equipment for assessing the adaptability of building products to salt spray environments. Only by ensuring the accuracy of equipment testing can a correct judgment be made on the corrosion resistance quality of the product. Therefore, it is necessary for the technical supervision department to conduct regular inspections on the quality of use of the salt spray test chamber.
The quality inspection of the in use salt spray test chamber is different from the usual product measurement and quality inspection. It requires the inspection unit to send personnel carrying instruments to the factory to inspect the main basic parameters of the in use salt spray test chamber. The purpose of the inspection is to ensure the quality of equipment use rather than simply judging whether the equipment meets the requirements. At the same time, after identifying the problems in the salt spray test chamber, the performance of the salt spray test chamber should be adjusted according to the situation. Technical services only judge the equipment as scrap or stop using in individual cases. Therefore, it requires high technical requirements for the testing personnel. Not only do they need to be familiar with the calibration methods and testing instruments of the salt spray test box, but they should also have a detailed understanding of the working principles and performance of various types of salt spray test boxes in order to be competent in the quality inspection of salt low concentration box use.
From the perspective of the nature and characteristics of the inspection of the salt spray test chamber in use, it is more appropriate for the comrades responsible for product environmental testing and equipment edge inspection in the technical supervision department to engage in this work, and they can combine the characteristics of technical supervision to force users of the salt spray test chamber to pay attention to the quality inspection of the use of the salt spray test chamber in use, in order to ensure the accuracy of the salt spray test.
3. Strengthen the cooperation between users and manufacturers of salt spray testing machines, so that both parties can improve their technical level and promote the development of product salt spray testing and the performance level of salt spray testing chambers.
From the adjustment of some salt spray test chambers in use, it can be seen that many users do not have a good understanding of the working principle and performance of the salt spray test machine used. Therefore, due to improper use and maintenance, there are many cases of salt spray sugar scattering obstacles. Some salt spray test chambers have minor problems, and users do not know how to eliminate them. To solve this problem, it is necessary to enhance users' understanding of the working principle and usability of the salt spray test chamber, and improve their maintenance skills for the salt spray test chamber they use.
