scope:

The scope of this Code is limited to the testing of fans after they have been installed in the systems for which they were intended. However, the same directions can be followed in a laboratory test. (The laboratory test performance may not be duplicated by a test after installation because of system effects.) The term "fan" implies that the machine is used primarily for moving air or gas rather than compression. The distinction between fans, blowers, exhausters, and compressors in common practice is rather vague; accordingly, machines that bear any of these names may be tested under the provisions of this Code. (It is conceivable that these machines can also be tested under the provisions of PTC 10, Compressors and Exhausters.)

This Code does not include procedures for determining fan mechanical and acoustical characteristics.

APPLICABILITY

A fan test is considered an ASME Code test only if the test procedures comply with procedures and allowed variations specified by this Code.
