3.1 Pretest
The following information is required to conduct rain tests adequately.
- a. General. Information listed in Part One, paragraphs 5.7 and 5.9, and Annex A, Task 405 of this Standard.
- b. Specific to this Method.
- (1) Rainfall rate.
- (2) Exposure surfaces/duration.
- (3) Test item preheat temperature.
- (4) Initial water temperature.
- (5) Wind velocity.
- (6) Water pressure (if appropriate).
- (7) Photographs as appropriate.
- (8) Test item weight, if required. This may be useful for detecting moisture intrusion in small test items where an internal visual inspection may not be feasible. In large test items, the precision of the scale limits ability to detect small amounts of water intrusion, so weighing of large items is not typically performed.
- c. Tailoring. Necessary variations in the basic test procedures to accommodate environments identified in the LCEP.
3.2 During Test
Collect the following information during conduct of the test:
- a. General. Information listed in Part One, paragraph 5.10, and in Annex A, Tasks 405 and 406 of this Standard.
- b. Specific to this Method. For test validation purposes, record deviations from planned or pre-test procedures or parameter levels, including any procedural anomalies that may occur.
3.3 Post-Test
The following post test data shall be included in the test report.
- a. General. Information listed in Part One, paragraph. 5.13, and in Annex A, Task 406 of this Standard.
- b. Specific to this Method.
- (1) Surfaces of the test item subjected to rainfall.
- (2) Duration of exposure per face.
- (3) Results of inspection for water penetration (amount and probable point of entry).
- (4) Results of operational checks.
- (5) Length of time for each performance check.
- (6) Any modifications from the test plan.
- (7) Photographs as appropriate.
- (8) If required, test item weights prior to and following exposures.
