ASTM E1240-88(1996)

1.1 This test method covers a test method for determining and reporting performance characteristics of Wind Energy Conversion Systems (WECS). It is intended to provide consumers and other users with an equitable basis for comparing the energy production performance and operating characteristics of WECS available in the marketplace.

1.2 This test method is not limited to WECS that produce electricity.

1.3 These procedures and practices were specifically compiled for small WECS (SWECS), but the test method may be generally applicable to WECS of all sizes.

1.4 This test method does not address issues of reliability, durability, or economics.

1.5 For all ratings dependent upon wind speed, the wind is taken to be that which is experienced at the centerline height of the WECS rotor. No standard heights for either the WECS rotor or the anemometer are assumed.

1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.7 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.
