檢測項目A full test cycle lasts 7 (Fig. 1) days and consists of:
3 times = 24h cycle A (Fig. 2; see also 7.2) without freezing phase, with 3 h salt spray phase (1 % NaCl solution)
3 times = 24h cycle B (Fig. 3; see also 7.2) without freezing phase, without salt spray, including assessment of specimens (or walk-around inspection)
1 time = 24h cycle C (Fig. 4; see also 7.2) with freezing phase, without salt spray
Fig.1: The placement of specimens in the test chamber shall be carried out exclusively during the
first cycle B of the evaluation phase. This also applies for the removal of the specimens.
Fig.: 2: 24 h-cycle A, with 3 h salt spray phase (1 % NaCl)
Fig.: 3: 24 h-cycle B without freezing phase, without salt spray, with evaluation phase
Fig. 4: 24 h-cycle C, with freezing phase, without salt spray
5.2 Test interruption
Interruption of the test or opening of the test chamber is only permitted during the evaluation phase (cycle B). The test chamber may not be switched off during this time.
No interruption of the salt spray phase is permitted. Longer interruptions of the cyclic climate phases are to be avoided; if unavoidable, they must be mentioned in the test report.
5.3 Placing specimens in the chamber
The specimens shall preferably be positioned in the chamber at an angle of 65° to 75° relative to the horizontal with the side to be tested uppermost. Components are to be positioned as agreed with the principal, preferably in the orientation in which they will be installed. The specimens (or components) may not contact each other or shield other specimens from the salt spray.
When using two separate test chambers for the salt spray phase and the cyclic climate phase, the specimens may not be allowed to dry-out when being transferred from one chamber to the other.
Vehicle components or special corrosion test plates may also be used as specimens for the test. In the case of components, special care shall be taken to ensure that salt solution does not pool on the specimen, as this will affect the test conditions (climate). If this cannot be avoided, such pooling must be removed at least once a week.
