First article. Two first article samples are required, one dedicated solely for EMI and RFI testing by biomedical personnel. All other required tests shall be performed on the second sample.

Tests. Tests shall be conducted to determine compliance with specification requirements. Where feasible, the same sample shall be used for the determination of two or more test characteristics. The following tests shall be conducted to determine compliance with this specification.

a. Minimum suction test. Using a Hg column with the apparatus running at room temperature, measure at least 500 mmHg suction at patient end of the suction tube.

b. Recharge time test. At room temperature, operating on the internal battery, run the apparatus until the internal battery(s) has expired. Condition the battery at -4°F for 8 hours. Next, using any one of the specified power supplies while temperature is rising from -4°F to 60°F during the first 1/2 hour then maintaining 60°F, charge the battery using the component charger, for a period of time not to exceed 24 hours. Test the battery for having a full charge in accordance with the instructions of the battery manufacturer. This test shall be conducted once per specified power supply, testing the charging time using each of the specified power sources (except internal battery and 110 volts, 400 Hz).

c. Fully charged battery operating time, operating temperature range, free airflow at patient end of suction tube. Using the internal battery that was charged in test “b” above (the last test conducted in b), without additional charge, condition the apparatus at 60°F for 8 hours. Next, in ambient temperature of -4°F run the apparatus for at least 35 minutes. During the first 32 minutes, alternately occlude and open (to atmosphere) the suction tube for 2 minute periods. Measure a free airflow of at least 30 LPM at the patient end of the suction during the last 2 min periods. Measure the vacuum to be at least 500 mmHg during the last minute (thumb valve occluded). Repeat this test except leave the patient tube continuously open to atmosphere during the first 34 minutes. Measure the free airflow to be at least 30 LPM during the 34th minute. Then measure the vacuum to be at least 500 mmHg during the last minute.
