CURRENT
ARP5448/7A
This standard details two methods of inspecting PTFE lined spherical or journal bearing wear outside the test apparatus. The methods described herein are applicable only to bearings which were unidirectionally loaded and the area of sliding wear is known and held constant throughout the dynamic test. The two methods described are: a Destructive Inspection - Cut and measure (not applicable to molded liners) b Nondestructive Inspection - Radial play (gauge) measurement

CURRENT
ARP5448/4
This test method outlines a recommended procedure for performing bond integrity tests of bonded peelable woven fabric reinforced polytetrafluoroethylene (PTFE) liners, hereafter referred to within this document as "PTFE liner" or "liner". The data from these tests shall be used to determine if the product meets the "bond integrity" requirements of the applicable specifications.
