Scope
This code is intended for commercial vehicles over 4500 kg (10 000 lb) with brake systems having typical service pressure ranges 0 to 14.1 mPa (0 to 2050 psi) hydraulic or 0 to 830 kPa (0 to 130 psi) air and is not directly applicable to vehicles with other systems. Air over hydraulic systems are to be tested as air systems.
Rationale
All of the revisions, updates, and corrections to this RP, although many, are clearly editorial in nature, and do not generate any substantive changes to the methodology and procedures of this RP. Figure 2, which may exhibit a somewhat different appearance, is identical to the previous Figure 2, except for the revisions and corrections required to address the various errors and omissions. The different appearance is due exclusively to the fact that the Figure had to be recreated from scratch, instead of just modifying the existing Figure.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
