records shall include drawings, specifications, design data, receiving inspection records,
processing and quality control standards, vendor catalogs and certifications, industry standards,
test reports, and rating data.
4.5.2 Defects. Conformance to 3.3 and 3.5 through 3.6, shall be determined by
examination for the defect listed in table IV. Examination shall be visual, tactile, or by
measurement with standard inspection equipment.
4.5.3 Compressor performance tests. Unless otherwise specified herein, the compressor
shall be tested for performance with a discharge pressure of 100 psig (690 kPa), at speeds of 600,
1200, 1800 and 2400 rpm. Tests shall be made in accordance with table VI. The compressor
shall be allowed to stabilize to ambient air temperature as specified in 4.2 for at least one hour
prior to start of test. Tests shall be run and data recorded progressively from lowest to highest
specified test speeds. At each test speed, discharge temperature shall be allowed to stabilize until
the rate of temperature change does not exceed 1°F (0.5°C) per minute, before the data is
recorded.

During testing, the rate of oil flow, air temperature and pressure at the compressor discharge, and
power input shall be measured and recorded at each speed.
4.5.3.1 Power input test. While operating as specified in 4.5.3, power input to the
compressor shall be measured and recorded at 2400 rpm, and 100 psig (690 kPa) load. Test shall
be repeated at no load. Maximum horsepower input shall not exceed value specified in table I to
determine conformance to 3.4.1.1.
4.5.3.2 Oil flow test. While operating as specified in 4.5.3, oil flow at 1775-1825 rpm,
and 37.5 psig (259 kPa), shall be measured and recorded. Values shall not exceed those specified
to determine to 3.4.1.2.
