4.5 Inspection methods.
4.5.1 Examination of product. Installation tools and their component parts shall be
visually examined to determine conformance to the requirements of this specification and
MS90387.
4.5.2 Spring return of handle. This test shall be conducted with and without each adjustable
tiedown strap accommodated by the tool. The handle and gripping device assembly of the tool
shall automatically return to their fully open position upon completion of the tension and cutting
operations. The tool shall be tested in the vertical and horizontal planes. When testing in the
horizontal plane, the gripping device shall be facing downward.
4.5.3 Gripping device test. Place the applicable SAE-AS33671 or SAE-AS23190/3
tiedown strap specified in table I through the strap guide and mark the strap at the point of entry
into the tool. Close the handle of the tool, bottoming on the stop without cutting the strap. Mark
the strap again at the point of entry into the tool. The distance between the marks shall not be
less than 3/16 of an inch, indicating the effective stroke length of the tool. The gripping device
shall return freely as the handle is opened.
4.5.4 High compression force. The tool shall perform satisfactorily after a compression
force of 150 pounds is exerted on the tool handle at a point 1 + 1/8 inch from the extremity of the
handle.

4.5.5 Normal compression force. The maximum compression force of table I shall
not be exceeded when cutting off the largest size cable strap accommodated by the tool, at the
highest tension setting, using the normal compression process. The compression force shall be
measured at a point on the tool handle 1 + 1/8 inch from the extremity of the handle.
