Voorbeeldzinnen

1. If the test is carried out with a plastic film this must be used as described below: Stretch the film over the open end of the drum and hold it in place with an elastic band.
2. A plastic film 0,01 to 0,02 mm thick may be used as a closure system. If the test is carried out with a plastic film this must be used as described below: Stretch the film over the open end of the drum and hold it in place with an elastic band.
3. A plastic film 0,01 to 0,02 mm thick may be used as a closure system. If the test is carried out with a plastic film this must be used as described below: Stretch the film over the open end of the drum and hold it in place with an elastic band. The strength of the band shall be such that when placed around the drum resting on its side, it stretches by only 25 mm when a mass of 0,45 kg is attached to its lowest point. Cut a 25 mm slit in the film, starting 50 mm from the edge of the drum. Ensure that the film is taut;
4. Operating frequencies above 3 GHz; b. An average output power density exceeding 80 W/kg; and c. A volume of less than 400 cm3; Note: 3A001.b.8. does not control equipment designed or rated for operation in any frequency band which is "allocated by the ITU" for radio-communications services, but not for radio-determination. c. Acoustic wave devices, as follows, and specially designed components therefor: 1. Surface acoustic wave and surface skimming (shallow bulk) acoustic wave devices (i.e., "signal processing" devices employing elastic waves in materials), having any of the following: a. A carrier frequency exceeding 2,5 GHz;
