ANSI EIA 00364-011A-1999 pdf download Resistance to Solvents Test Procedure for Electrical Connectors and Sockets
1. SCOPE This procedure is to determine the ability of connector materials to withstand solvents which may be used to clean components.
2. APPARATUS
2. 1 A beaker, container or vapor degreaser made of non-reactive material and of sufficient size.
2. 2 A wire mesh basket of sufficient size, if applicable.
2. 3 A weight scale accurate to within 1 gram. 3 . SOLVENTS CAUTION: The solvents in Table 1 exhibit some potential for health and safety hazards. The following safety precautions shall be observed:
a) Avoid contact with eyes. Chemical goggles should be worn while performing this test.
b) Avoid prolonged contact with skin.
c) Provide adequate ventilation.
d) Avoid open flame.
e) Refer to the manufacturer’ s material safety data sheets for emergency first aid procedures.
3. 1 One of the two groups of solvents as shown in Table 1 shall be chosen to perform the test contingent on the cleaning process involved. Unless otherwise specified in the detail specification, test samples shall be exposed to Group 1 solvents.
3. 1. 1 In the event solutions other than those specified in Table I, are to be used, those solutions shall be specified in the detail specification along with time/temperature levels involved.
4. TEST PROCEDURE
4. 1 When specified, each individual test specimen shall be identified and weighed. Said weight shall be recorded.
4. 2 Separate test specimens shall be exposed to each solution involved.
4. 3 All solutions within each group selected shall be included in the test.
4. 4 An appropriate vessel large enough to accept the test specimen shall be selected.
4. 5 The vessel shall be filled to a level sufficient to cover the test specimen plus 2. 54cm (1. 0 inch) minimum.
4. 6 The solution shall be heated to the temperature indicated. The tolerance of the temperature shall be +2. 8°C/-0°C (+5°F/-0°F) and maintained for 15 minutes prior to proceeding.
4. 7 The test specimen shall be immersed in the solution and allowed to stand for the period of time indicated.
4. 8 After removal from the solution, the test specimen shall be allowed to recover to room ambient conditions and remain in that state for 5. 0 minutes prior to further examination.
4. 9 When specified and prior to visual examination, the test specimen shall be weighed and said weight recorded.
5. 0 Unless otherwise specified, the test specimens shall be visually examined under 10X magnification. 5. SUMMARY 5. 1 The following details shall be specified in the individual specification:
5. 1. 1 The number of specimens to be tested per solution.
5. 1. 2 The extent of deterioration allowed including the extent of weight gain if applicable.
5. 1. 3 The solvent group to be used.
