Scope
1.1 This test method was designed to evaluate an engine
oil’s resistance to aeration in automotive diesel engine service.
It is commonly referred to as the Engine Oil Aeration Test
(EOAT). The test is conducted using a specified 7.3 L, directinjection, turbocharged diesel engine on a dynamometer test
stand. This test method was developed as a replacement for
Test Method D892 after it was determined that this bench test
did not correlate with oil aeration in actual service. The EOAT
was first included in API Service Category CG-4 in 1995.

1.2 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.2.1 Exception—Where there is no direct SI equivalent, for
example, screw threads, national pipe threads/diameters, and
tubing size.
1.3 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT

This document presents procedures and acceptance limits
for contact ultrasonic inspection of steel butt welds in the
thickness range of 1/4 to 2 inches. The acceptance limits described
in the following sections are compatible with those set
forth in SSC-177, “Guide for Interpretation of Nondestructive
Tests of Welds in Ship Hull Structures” for radiographic inspection
and should therefore result in satisfactory ship welds.
