Abstract
A test procedure which was used to check the effects on an industrial sound level meter (ISLM) of exposure to environmental conditions of temperature and humidity variations, is described. Included is a list of equipment needed to perform the tests and the configuration in which the equipment is to be used. The ISLM's sensitivity should be within a certain decibel range when exposed to these environmental factors. Over the temperature range of minus 10 degrees centigrade to 50 degrees centigrade, the ISLM's sensitivity variation should be less than 0.5dB, or an appropriate correction should be used. Also, over the humidity range from 5% to 90%, the ISLM's sensitivity variation would be less than 0.5dB. All tests were performed at the frequency of 500Hz. The test requirements are derived from the following sources: 1) NIOSH regulation which gives a program for certifying industrial sound level meters; and 2) American National Standards Institute's Specification for Sound Level Meters.
