are required to be tested, magnetic particle testing shall be used only in
areas inaccessible to either radiographic or ultrasonic testing. Retest
defective areas after repair.

3.8.2
Load Indicator Washers
3.8.2.1
Load Indicator Washer Compression
Load indicator washers shall be tested in place to verify that they have
been compressed sufficiently to provide the 0.38 mm 0.015 inch gap when the
load indicator washer is placed under the bolt head and the nut is
tightened, and to provide the 0.13 mm 0.005 inch gap when the load
indicator washer is placed under the turned element, as required by ASTM F
959M ASTM F 959.
[3.8.2.2
Load Indicator Gaps
**************************************************************************
NOTE: Use this paragraph on large complex
structural steel systems or on jobs where minimal on
site inspection is expected.
**************************************************************************
In addition to the above testing, an independent testing agency as approved
by the Contracting Officer, shall test in place the load indicator gapson
20 percent of the installed load indicator washers to verify that the ASTM
F 959M ASTM F 959 load indicator gaps have been achieved. If more than 10
percent of the load indicators tested have not been compressed sufficiently
to provide the average gaps required by ASTM F 959M ASTM F 959, then all in
place load indicator washers shall be tested to verify that the ASTM F 959M
ASTM F 959 load indicator gaps have been achieved. Test locations shall
be selected by the Contracting Officer.
][3.8.3
Overhead, Top Running Crane Rails and Beams
**************************************************************************
NOTE: Include paragraph for overhead, top running
cranes. Underhung bridge cranes and monorail
systems are normally provided with their own
patented track systems and do not normally require
the tight tolerances specified for overhead, top
running cranes.
**************************************************************************
Runway rails and beams shall be surveyed (horizontally and vertically)
after installation to verify compliance with the tolerance requirements of
