Liquidos Penetrantes

STANDARD TEST METHOD FOR
LIQUID PENETRANT EXAMINATION
SE-165
(Identical with ASTM Specification E 165-95)

1.

Scope

1.4 The values stated in inch-pound units are to be
regarded as the standard. SI units are provided for
information only.

1.1 This test method covers procedures for penetrant
examination of materials. They are nondestructive testing methods for detectingdiscontinuities that are open
to the surface such as cracks, seams, laps, cold shuts,
laminations, through leaks, or lack of fusion and are
applicable to in-process, final, and maintenance examination. They can be effectively used in the examination
of nonporous, metallic materials, both ferrous and nonferrous, and of nonmetallic materials such as glazed
or fully densified ceramics, certain nonporousplastics,
and glass.

1.5 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. For specific hazard statements, see Notes
5, 12, and 20.

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 dealing with the liquid penetrant examinationof materials and parts. Agreement by the user and
the supplier regarding specific techniques is strongly
recommended.
1.2.3 For use in the organization of the facilities
and personnel concerned with the liquid penetrant examination.
1.3 This test method does not indicate or suggest
criteria for evaluation of the indications obtained. It
should be pointed out, however, that after indicationshave been produced, they must be interpreted or classified and then evaluated. For this purpose there must
be a separate code or specification or a specific
agreement to define the type, size, location, and direction
of indications considered acceptable, and those considered unacceptable.
