4.5.2 Tests.
4.5.2.1 Test conditions. Prior to test, the compressor shall be lubricated
with military oils and greases. Oils shall be those designated for use in
ambient temperatures at place of test. The compressor unit shall operate as
specified herein without maintenance other than the contractor's recommended
normal scheduled maintenance as established by a maintenance schedule prepared
and submitted by the contractor prior to test. Unless otherwise specified
herein, tests shall be conducted with all compressor unit components and
accessories, including the air intake extension, installed and functioning
normally. Capacity shall be determined in accordance with the ASME Performance
Test Code (PTC-9) or by calculating capacity based on weight of air delivered in
a given time. Condensate removed from the air shall not be included as part of
the compressor capacity. If the weight method is used, the reservoir (minimum
volume 1000 cubic inches) shall be filled to 2000 plus or minimum 100 psig, and
the capacity shall be determined by the following formula:
=
Cubic feet per minute (free air)
Where: CFM
W1
=
Empty weight of capacity check assembly (lb.)
W2
=
Full weight of capacity check assembly (lb.)
R
=
Air temperature at cooling fan in degrees, Rankline (Farenheit,
absolute)
= Time required to fill resevoir in minutes
t
= Barometric pressure in inches, Hg.
