4.4 Test conditions. Unless otherwise specified, the sealing compound shall be tested without treatment or preconditioning of any sort. Tests shall be conducted at a temperature of 21°to 27°C (70° to 80°F). Unless otherwise specified in the specific test method, the tolerance for test temperatures shall be ±2°C (±4°F). All metal panels shall be cleaned by wiping with bleached cheesecloth dampened with methyl ethyl ketone.
4.4.1 Manufacturer's data. The manufacturer shall submit a material safety data sheet prepared in accordance with FED-STD-313 which shows the sealing compound is not a health hazard to individuals under normal conditions of usage.
4.5 Test methods

4.5.1.2 Test panels. Recessed aluminum panels conforming to the design and measurement of Figure 1 shall be placed in a desiccator for one hour and then weighed to the nearest milligram (mg). The required number of panels shall then be filled with sealing compound and air dried in a circulating oven for 46 ± 0.25 hour at 70° ± 1°C (158° ± 2°F).
4.5.1.3 Procedure After removal from the oven and cooling to room temperature in a desiccator, the specimens shall be weighed to the nearest mg and then immersed for 22 ± 0.25 hour in 250 milliters (ml) of the respective fluid per specimen. After immersion, excess oil shall be removed from the specimens by wiping with P-D-680 solvent. Excess hydraulic fluid shall be
