The latest salt spray test chamber GBT10125-2012 standard test cycle
9. Test Cycles
9.1 The duration of the test should be determined based on the relevant standards applicable to the materials or products being tested. If no specific standard exists, the test duration can be agreed upon through consultation between the involved parties.
The recommended test cycles 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 specified test period, the spray must not be interrupted. The salt spray chamber should only be opened briefly when necessary for sample inspection. Any opening should be kept to a minimum to avoid affecting the consistency of the test environment.
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 frequent inspections could interfere with the integrity of the results.
9.4 For specimens scheduled for a set test period, periodic inspections may be conducted. However, during such inspections, care must be taken not to damage the surface of the test specimen. Additionally, the frequency and duration of opening the salt spray chamber should be minimized to ensure accurate and reliable results.
It is important to follow these guidelines to maintain the validity of the test outcomes. Proper documentation of all observations and test conditions is also highly recommended to support traceability and reproducibility.
