Options. performing a The options are limited functional test prior to (1) Teat time (28 to 84 days). (2) Teat config~ation - whether the test item shall be exposed in other than an unsealed condition. 1.4.1 J2hoiceof test Dhas~ a. The operational purpose of the test item. From the requirements, determine the functions to be performed by the equipment and any limiting conditions, (e.g. storage, human factors aspects, whether it is a large volumellow cost/ expendable item, etc.). b. Required test data.
The primary questions that may be addressed after the fungus test are: (1) Will fungus grow on the item? (2) How rapidly will it grow on the test Item? (3) How does the fungus growth affect the test item? (4) . To what extent will the fungus affect the mission of the item? ) (5) Can the test item be stored effectively in a field environment? (6) Ia the test item safe for use following fungal growth? (7) Are there simple reversal processes, e.g. wiping off fungal growth? c. Selection of test phaaes. Three test phases are included within Method 508.2 (pre-test, ch~ber and performance). Based on the test requirements document, determine which phases are applicable.
(1) Phase 1 (pre-test) - Phase 1 is conducted in all cases to provide baseline data. (2) Phase II (chamber) - Phase II ia the basic fungus test and is conducted in all cases. (3) Phase’III (perfO~ance) with the performance requirements test. - Phase III is used to determine’compliance of the test item following the fungus chamber 1.4.2 ce fr d ~ it on&. Recognizing that at leaat two of the test phases must be conducted, the primary decisions must be made concerning test duration and test item configuration. MSTHOD 508.2 508.2-3
