For a client we investigated the sound pressure level of a hydraulic generator package. The Machinery directive requires determination of the highest sound pressure level at any bystander position, e.g. at 1,6 m height and 1 m distance. For this package that so-called A-weighted emission sound pressure level was 85 dB, found close to a grid with a large fan behind it. This category includes methods that were categorized as conditional test methods before our method categories were revised. Because some of these methods have been cited in state rules and permits under their Conditional Test Method (CTM) designation, we have created a category for them and called it "Historic Conditional Methods".

Surface temperature measurements in internal combustion engines have been conducted previously using phosphor thermometry [16,26,27,28,29,30, 31, 32,33,34]. However, to the author's knowledge. Reciprocating single acting compressors are generally of one-stage or two-stage design. Compressors can be of a lubricated, non-lubricated or oil-less design. In the single-stage compressor, air is drawn in from the atmosphere and compressed to final pressure in a single stroke. The single-stage reciprocating compressor is illustrated in.

SOUND LEVEL METERS The primary tool for noise measurement is the Sound Level Meter (SLM). The compromises with sound level meters are between accuracy, features and cost.
The precision of a meter is quantified by its type (see standards IECor ANSI S for more details). 20 50 Frequency Hz 2K 5K 10K 20K Human response to pure tones of equal Sound Pressure Level.
The B. C and D scales on noise meters are used for more specialized noise readings. The D scale, for instance, is the one being considered for use in measuring the noise of jet engines .TRAINING COURSE SERIES No.
