9. Test Cycles
9.1 The duration of the test should be determined based on the relevant standards for the materials or products being tested. In cases where no specific standard exists, the test period can be decided through mutual agreement between the parties involved.
The recommended test durations include 2 hours, 6 hours, 24 hours, 48 hours, 72 hours, 96 hours, 144 hours, 168 hours, 240 hours, 480 hours, 720 hours, and 1000 hours. These time intervals are commonly used in various industries to evaluate corrosion resistance under controlled conditions.
9.2 During the designated test period, the spray must not be interrupted. The salt spray chamber should only be opened briefly when necessary for sample inspection. Any unnecessary opening may affect the consistency of the test results.
9.3 If the test is stopped due to the onset of corrosion, samples must be checked regularly. Therefore, these samples should not be tested alongside those that require a fixed test duration, as this could lead to inconsistent data.
9.4 For samples scheduled for a set test period, periodic inspections are allowed. However, during these inspections, care must be taken not to damage the test surface. Additionally, the frequency and duration of opening the salt spray chamber should be minimized to maintain test integrity.
It's important to follow these guidelines to ensure accurate and reliable results. Proper documentation of test conditions and any observations made during the process is also essential for future reference and analysis. The salt spray test is widely used in industries such as automotive, aerospace, and construction to assess the durability of coatings and materials against corrosive environments.
