Product Test Codes Product Test Code standards specify the methods to be utilized for the measurement of the noise emissions of a specific class of equipment. Most product test codes rely on basic underlying standards for the measurement of sound pressure and sound power levels. The test code specifies operational modes and test conditions specific to the class of equipment. The following standards provide rules and guidelines for drafting product test codes and for utilizing the underlying sound pressure level and sound power level measurement standards in product test codes.

 A note about ECMA, ISO and ANSI test code standards and declaration standards for ITTE equipment – Many of the ITTE test codes are published by ECMA, ISO and ANSI. The current process is that new or revised standards are developed as a part of the ECMA process, as ECMA standards can be adopted quickly. The ECMA standards are then submitted to ISO for approval as an ISO standard and then submitted to ANSI for adoption as a consensus international standard. When the entire process is completed, the ECMA, ISO and ANSI standards become equivalent. Additional References
