استاندارد ASTM A 503

در خصوص انجام تست آلتراسونیک بر روی

Forged Cracking Shafts

Scope
1.1 This is an acceptance specification for the ultrasonic
inspection of forged steel crankshafts having main bearing
journals or crankpins 4 in. [100 mm] or larger in diameter.
1.2 This specification covers the testing equipment required
and the test procedure to be followed, and it defines the critical
and noncritical areas and limits of acceptance.
1.3 This specification is intended to cover both continuous
grain flow (CGF) crankshafts for medium and high speed
diesel engines as well as solid (slab) forged crankshafts for
other applications.
1.4 The values stated in either inch-pound units or SI
(metric) units are to be regarded separately as the standard.
Within the text and tables, the SI units are shown in brackets.
The values stated in each system shall be used independently of
the other. Combining values from the two systems may result
in nonconformance with the specification.
1.5 Unless the order specifies the applicable “M” specification designation, the inch-pound units shall be used.
1.6 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.

Standard Practice for
Liquid Penetrant Examination for General Industry

 Scope:
1.1 This practice
covers procedures for penetrant examina-
tion of materials. Penetrant testing is a nondestructive testing
method for detecting discontinuities that are open to the surface
such as cracks, seams, laps, cold shuts, shrinkage, laminations,
through leaks, or lack of fusion and is applicable to in-process,
final, and maintenance testing. It can be effectively used in the
examination of nonporous, metallic materials, ferrous and
nonferrous metals, and of nonmetallic materials such as non-
porous glazed or fully densified ceramics, as well as certain
nonporous plastics, and glass.
1.2 This practice also provides a reference:
1.2.1 By which a liquid penetrant examination process
recommended or required by individual organizations can be
reviewed to ascertain its applicability and completeness.
1.2.2 For use in the preparation of process specifications and
procedures dealing with the liquid penetrant testing of parts
and materials. Agreement by the customer requesting penetrant
inspection is strongly recommended. All areas of this practice
may be open to agreement between the cognizant engineering
organization and the supplier, or specific direction from the
cognizant engineering organization.
1.2.3 For use in the organization of facilities and personnel
concerned with liquid penetrant testing.
1.3 This practice does not indicate or suggest criteria for
evaluation of the indications obtained by penetrant testing. It
should be pointed out, however, that after indications have
been found, they must be interpreted or classified and then
evaluated. For this purpose there must be a separate code,
standard, or a specific agreement to define the type, size,
location, and direction of indications considered acceptable,
and those considered unacceptable.
