1、Designation: E433 71 (Reapproved 2013)Standard Reference Photographs forLiquid Penetrant Inspection1This standard is issued under the fixed designation E433; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision

2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These reference photographs are supplied as a means ofestablishing types and characteristics of surface discontinuitiesdetectable b

3、y the penetrant examination methods. They may beused as a reference for acceptance standards, specifications anddrawings.1.2 Actual dimensions including maximum length of indi-cations and number of indications per unit area must bespecified by the users of this document. No attempt has beenmade to e

4、stablish limits of acceptability or the metallurgicalcause of a discontinuity.NOTE 1Examples of these reference photographs are shown in Figs.1-8.2.

5、enetrant Inspection33. Classifications3.1 TypesFor the purposes of this standard there are twotypes of indications, which are defined as follows:3.1.1 Type I IndicationsThose in which neither of themeasurable dimensions is greater than three times the other.3.1.2 Type II IndicationsThose in which on

6、e of the mea-surable dimensions is at least three times greater than the other.3.2 ClassesFor purposes of this standard there are fourclasses of indications which are defined as follows:A. SingleB. Multiple unalignedC. Multiple alignedD. Intersection of surfaces (threads, corners, fillets, etc.)4. I

7、dentification4.1 The types of discontinuity indications covered by thesereference photographs are listed and described in Table 1. Eachtype of discontinuity indication is designated by a Romannumeral. The class of indication is designated by the letters Athrough D. Individual photographs within type

8、 and class areidentified by numbers. Each reference photograph is, therefore,identified with the proper Roman numeral, letter, and number.5. Method of Preparation5.1 The reference photographs were reproduced from mas-ter photographs which are the property of ASTM. The photo-graphs retain the origina

9、l photographic contrast.6. Basis for Use of Reference Photographs6.1 These reference photographs are intended for use whenspecified in the inquiry, contract, order material specification,or applicable code, and when the severity is mutually agreedupon between the manufacturer and the purchaser. It i

10、srecognized that it is impossible to rigidly interpret indicationsfrom a set of photographic references. Consequently, there is aneed for close cooperation between manufacturer and pur-chaser.6.2 Zones of inspection and severity levels in each zoneshall be shown on applicable drawings or otherwise s

11、pecified.Unless otherwise specified all accessible surfaces shall beexamined.6.3 These reference photographs are intended to depictpenetrant indications of surface discontinuities. They are notintended to indicate the depth of such discontinuities.6.4 Applicable penetrant examination methods and tec

12、h-niques are described in the latest issue of Test Method E165.7.
