In the field of light industrial products, the corrosion resistance of metal deposits and chemical treatment layers is of crucial importance. It directly affects the service life, performance, and appearance of products. The ASTM B117 standard, “Standard Practice for Operating Salt Spray (Fog) Apparatus,” provides a unified and reliable approach to conduct salt spray tests, which is widely used in evaluating the corrosion resistance of various materials and coatings.
The LISUN YWX/Q-010 Salt Spray Test Chamber is designed to meet the requirements of ASTM B117 and multiple other standards. By using this test chamber, accurate and reproducible salt spray tests can be carried out, providing valuable data for the development and quality control of light industrial products.
Light industrial products are widely used in daily life and various industries. Metal components and coatings in these products are often exposed to different environments, which may lead to corrosion. Corrosion not only affects the aesthetic appearance of products but also reduces their mechanical properties, electrical conductivity, and overall functionality. For example, in the case of light industrial products such as household appliances, decorative items, and small hardware, corrosion can cause the surface to peel off, rust spots to appear, and even affect the normal operation of the product. Therefore, evaluating and ensuring the corrosion resistance of metal deposits and chemical treatment layers in light industrial products is essential to improve product quality, extend service life, and enhance customer satisfaction.
ASTM B117 standard specifies the operating procedures and requirements for salt spray (fog) apparatus. It defines the test conditions, including the concentration of the salt solution, spray rate, temperature, and humidity, to ensure the consistency and comparability of test results. The standard also provides guidelines on sample preparation, installation, and evaluation methods.
• Salt Solution: The standard requires using a 5% ± 1% sodium chloride (NaCl) solution by mass in distilled or deionized water. The pH value of the solution should be maintained between 6.5 and 7.2.
• Spray Rate: The salt spray deposition rate should be within the range of 1 – 2 mL/80 cm²/h, measured by collecting the spray in a suitable collector over a 16-hour test period.
• Temperature and Humidity: The test chamber temperature should be maintained at 35 ± 2 °C. The relative humidity inside the chamber is not explicitly specified in ASTM B117 but is usually controlled within an appropriate range to ensure stable test conditions.
• Test Duration: The test duration depends on the specific requirements of the product or material being tested. It can range from a few hours to several days or even weeks, depending on the expected corrosion resistance level.
The LISUN YWX/Q-010 Salt Spray Test Chamber is designed to perform salt spray corrosion tests on components, parts, electronic and electrical parts, metal materials, and industrial products, including light industrial products. It is an ideal device for evaluating the corrosion resistance of metal deposits and chemical treatment layers in accordance with ASTM B117 and other relevant standards.

Before the test, the samples of light industrial products with metal deposits and chemical treatment layers need to be carefully prepared. The samples should be cleaned to remove any contaminants, oils, or dirt on the surface. The cleaning method should be selected according to the nature of the sample and the requirements of ASTM B117. After cleaning, the samples are dried thoroughly.
The prepared samples are installed on the sample rack in the test chamber. The sample rack of the LISUN YWX/Q-010 test chamber is equipped with V-shaped grooves and O-type round sticks, which can hold the samples at an appropriate angle (20 ° ± 5 °) to ensure that the salt spray can evenly contact the surface of the samples. If necessary, special sample racks can be customized according to the shape and size of the samples.
According to the requirements of ASTM B117, a 5% ± 1% sodium chloride solution is prepared using distilled or deionized water. The pH value of the solution is adjusted to within the range of 6.5 – 7.2 using appropriate reagents. The prepared salt solution is poured into the solution tank of the test chamber.
The test parameters, such as test type (NSS, AASS, or CASS), spray method (continuous, intermittent, or programmable), test duration, and temperature, are set according to the testing requirements. The LISUN YWX/Q-010 test chamber allows for easy parameter setting through its control panel.
After all the preparations are completed, the test is started. The test chamber sprays the salt solution in the form of fine mist, creating a salt spray environment. During the test, the safety protection mechanisms of the test chamber monitor the operating conditions in real-time. If any abnormal situations, such as low water level, over-temperature, or low air pressure, occur, the alarm will be triggered, and the test may be automatically suspended to ensure the safety of the test and the equipment.
After the specified test duration, the samples are removed from the test chamber. The corrosion status of the samples is evaluated visually and quantitatively. Visual evaluation includes observing the appearance of the samples, such as the presence of rust spots, peeling, or blistering. Quantitative evaluation can be carried out by measuring the weight loss of the samples, the area of corrosion, or using electrochemical methods to assess the corrosion rate. The evaluation results are compared with the relevant standards or product requirements to determine whether the corrosion resistance of the metal deposits and chemical treatment layers of the light industrial products meets the expectations.
A light industrial product manufacturer produces decorative hardware with metal coatings. To ensure the quality and durability of the products, ASTM B117-based salt spray tests are conducted using the LISUN YWX/Q-010 test chamber. Samples of the decorative hardware are prepared and installed in the test chamber. A neutral salt spray test (NSS) is carried out for 48 hours. After the test, the samples are evaluated. The results show that some samples with poor coating quality have obvious rust spots, while those with high-quality coatings remain intact. Based on the test results, the manufacturer adjusts the coating process to improve the corrosion resistance of the products.
