Fans — Laboratory methods of testing air circulating fans
This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…
Measurement of radioactivity — Gamma emitting radionuclides — Rapid screening method using scintilla...
ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563).
This test method can be used for the measurement of any potentially…
