Historical Standard: ASTM D6011-96(2003) Standard Test Method for Determining the Performance of a Sonic Anemometer/Thermometer
SUPERSEDED (see Active link, below)
ASTM D6011
1. Scope
1.1 This test method covers the determination of the dynamic performance of a sonic anemometer/thermometer which employs the inverse time measurement technique for velocity or speed of sound, or both. Performance criteria include: ( a ) acceptance angle, ( b ) acoustic pathlength, ( c ) system delay, ( d ) system delay mismatch, ( e ) thermal stability range, ( f ) shadow correction, (g) velocity calibration range, and ( h ) velocity resolution.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
