Standard Test Method for
Liquid Penetrant Examination1
This standard is issued under the ﬁxed designation E 165; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates aneditorial change since the last revision or reapproval.
1. Scope 1.1 This test method2 covers procedures for penetrant examination of materials. They are nondestructive testing methods for detecting discontinuities 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. Theycan 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 nonporous plastics, and glass. 1.2 This test method also provides a reference: 1.2.1 By which a liquid penetrant examination process recommended or required by individual organizations can be reviewed to ascertainits applicability and completeness. 1.2.2 For use in the preparation of process speciﬁcations dealing with the liquid penetrant examination of 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 doesnot indicate or suggest criteria for evaluation of the indications obtained. It should be pointed out, however, that after indications have 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 thoseconsidered unacceptable. 1.4 The values stated in inch-pound units are to be regarded as the standard. SI units are provided for information only. 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 regulatorylimitations prior to use.
