4.2.1 First article sample. Prior to the start of production and within 30 days after the date of award of the
contract or order, one machine of each configuration shall be made ready for approval of the contracting officer or
his authorized representative to conduct the tests and examinations specified in table I and tests specified in 4.2.2
through 4.2.10 (see 6.2 and 6.3). Approval of the tested sample by the contracting officer or his authorized
representative shall not relieve the supplier of the responsibility of compliance with the requirements of this
specification. Type I machines which satisfactorily pass all first article tests do not require retest for Type II
applications. Disposition of the first article sample shall be in writing at the direction of the contracting officer or his
designated representative (see 6.2 and 6.3).
4.2.1.1 Test conditions. Unless otherwise specified, the test load for the tests specified in 4.2.3 through 4.2.7
shall consist of the washer-extractor maximum dry weight load capacity of test cloths. Test cloths shall be prepared
from a white cotton fabric of uniform texture and permanent finish, having a warp of 48, a weft of 48, and weighing
not less than 0.33 pound per square yard. Permanent finish, sanforized, white cotton cloth, known as Indianhead
cloth may be used. The test cloths shall be cut to 24 by 36 inches and shall be double-hemmed to a finished size of
22 by 34 inches. The dry weight of test cloths shall be determined at a temperature of 70±2 °F. The ambient
conditions where the tests are conducted shall be 75±10 °F and 60±20 percent relative humidity.
4.2.2 Disassembly. Prior to conducting the inspection tests, the sample machine shall be disassembled to the
