This Standard specifies the requirements of electromagnetic compatibility (EMC) for 800 MHz CDMA digital cellular mobile telecommunication system: MS and ancillary equipment that receive and transmit voice and/or data, including measurement methods, frequency range, limits and performance criteria etc. This Standard is not only applicable to portable and vehicle-mounted mobile stations but also to those powered by AC and used at fixed locations.
This Standard specifies the test method of adopting the inductively coupled plasma optical emission spectrometry (ICP-OES) to determine the silicon content in motor gasoline. This Standard is applicable to determine the silicon content of 1.0mg/kg ~ 50.0mg/kg in the motor gasoline (the volume fraction of oxygen-containing compounds shall not exceed 15%), such as motor gasoline containing methyl tert-butyl ether, motor methanol gasoline (M15) and motor ethanol gasoline (E10). For the motor gasoline sample with silicon content higher than 50.0mg/kg, it can be diluted by the isooctane with higher proportion, then determine according to this Standard method; but its precision has not been statistics yet.
