MIL-STD-1330D(SH) APPENDIX D
w/ Change 1
k. Equipment for performing maintenance on the SQM. For checking the ultraviolet lamp intensity, a
research radiometer, model IL1400 and a detector at 185 nm, model SEL185 both available from International Light
(978) 465-5923, and additionally, an adapter, part number 10528, available from Photo Emission Tech., Inc. (805)
499-7667. For checking the sensor electronics, a calibration load model #60054 available from Photo Emission
Tech, Inc. (805) 499-7667.
D.6 Reagents.
D.6.1 The following are required to prepare 5 ppm laboratory standards in a chemistry laboratory:
a. New, unused NAVSEA approved halogenated solvent that will be used as the cleaning solvent is required to prepare laboratory standards (i.e., if HFE-7100 will be used as the cleaning solvent, then HFE-7100 must be used to prepare the laboratory standard).
b. MS2190-TEP, MIL-PRF-17331, if preparing the HCFC-225 or CFC-113 laboratory standards.
c. Krytox Grease DuPont 240AC, MIL-PRF-27617 if preparing the HFE-7100 laboratory standards. D.6.2 The following are required to perform OSEE analysis of solvent:
a. Sparkleen available from Fisher Scientific, catalog number 04-3204 (3.25 pounds per box). Prepare the Sparkleen cleaning solution in a container (D.5.1(i)) by diluting with tap water per the manufacturer's instructions. Use of other cleaners is not allowed. Disposal shall be in accordance with local, state, and federal regulations.
b. Tap water.
c. New, unused NAVSEA approved halogenated solvent as specified in 4.4 is needed to final clean glassware and rinse evaporating dishes. New, unused NAVSEA approved halogenated solvent is also required to prepare laboratory standards.
D.7 Samples. The following samples are required for analysis:
a. If baseline applies, a sample of new-unused solvent of not less than 20 mL shall be collected from each container or drum of each lot or batch.
b. A sample of solvent used as a final cleaning solvent shall be not less than 20 mL in a glass bottle with a screw cap having a Teflon liner.
D.8 Preparation and maintenance of apparatus. D.8.1 Setting hot plate temperature.
D.8.1.1 For the hot plate of D.5.1 (c), adjust the rheostat and measure the surface temperature of the hot plate using the thermometer of D.5.1 (j). Continue adjusting until the desired temperature (85 to 90 °F for CFC-113 or HCFC-225 or 90 to 100 °F for HFE-7100) is attained and stays below the maximum specified temperature for 10 minutes. Note the digital readout for each of these temperatures (e.g., 0.2 may equate to 90 °F and 0.3 may equate to
100 °F). For subsequent use of this hot plate, the hot plate can be set using the digital readout and measurement of temperature is not necessary. The hot plate shall be checked every 3 months.
D.8.2 Set up SQM.
D.8.2.1 Turn the power to the control unit OFF. Inspect the sensor to confirm that the manufacturer installed a
0.25-inch diameter aperture. The aperture is needed so that only the horizontal surface at the center of the dish in the evaporating area is measured.
CAUTION 1: During installation, the person installing the aperture MUST be grounded. Electrostatic
discharge can damage the sensor electronics. At a minimum, wear a properly grounded conductive wrist strap. Also during installation, handle the apertures with the tweezers provided to prevent contamination that can seriously degrade sensor performance.
If it was not installed, following the manufacturer's instructions, install the 0.25-inch diameter aperture on the sensor.
