1.0 SCOPE

1.1 This procedure establishes the requirements for the liquid penetrant examination of

metallic materials and weldments in accordance with the applicable codes specified inparagraph 2 below. It applies to liquid penetrant examination using the color contrastand solvent removable technique in accordance with ASME Section V, Article 6.

2.0 APPLICABLE CODES

2.1 Liquid penetrant examination shall conform to the applicable provisions of thefollowing codes effective on the date specified in the contract. The applicable codeand addenda is referenced on each shop drawing.

2.2 Codes1. ASME Boiler and Pressure Vessel Code, Sections I, V, and VIII.2. ANSI B31.1 and B31.3

3.0 PERSONNEL QUALIFICATIONS

3.1 Liquid penetrant examination shall be performed by personnel qualified in accordancewith Boccard Pipe Fabricators, Inc.’s Written Practice for Qualification andCertification of NDE Personnel. This qualification uses as a guide the ASNTRecommended Practice SNT-TC-1A.

3.2 Final acceptance and interpretation shall be performed by a qualified Level II or IIIexaminer.

4.0 PENETRANT MATERIALS

4.1 Penetrant materials shall conform to the Control of Contaminants requirementsoutlined in ASME Section V, Article 6. Typical brand and group used in theexamination may be:

Cleaner – Sherwin Inc., Type DR60Penetrant – Sherwin Inc., Type DP40Developer – Sherwin Inc., Type D100

4.2 Penetrant materials shall not contain more than one percent by weight of either sulfuror chlorine.



Page 3 of 3

4.3 The manufacture’s certification of test results which show the material brand, type, andbatch numbers, shall be maintained by the Quality Assurance Department.

5.0 SURFACE PREPARATION

5.1 The surface to be examined may be in the as welded, as forged, or as rolled conditions.Grinding or machining is allowed to remove surface irregularities that could maskunacceptable discontinuities. Cleaning by blasting with steel shot, dull sand, or vaporblasting, is prohibited.

6.0 EXAMINATION SEQUENCE

6.1 Verify visually that the surface to be examined and adjacent surfaces within one (1) incare dry and free of dirt, grease, oil, lint, scale, and welding flux and weld splatter. The

illumination in the examination area shall be sufficient to clearly define all apparentindications. A minimum light intensity of 100 fuci (1000 Lx) is required to ensureadequate sensitivity during the examination and evaluation of indications. The lightsource intensity shall be checked one time and a record kept on file.

6.1.1 CalibrationThe Light Meter shall be calibrated at least once a year or wherever the meter hasbeen repaired. If the meters have not been in use for more than one year or more,calibration shall be done before being used.

6.2 The temperature of the penetrant and part to be examines shall be between 50̊ F and125˚ F. Heating or cooling of the part is allowed to maintain the required temperatureduring the examination.

6.3 Clean the surface to be examined with an approved cleaner (Sherwin Type DR60).Spray surface to wet and dilute, removing all traces of contaminant. Wipe with a cleanlint-free absorbent paper or cloth to remove excess cleaner.

6.4 After all visible traces of the cleaner have evaporated; wait at least one (1) minutebefore applying the penetrant.

6.5 Apply an approved penetrant (Sherwin Type DP40) using an aerosol spray can or bybrushing. Coat the surface thoroughly and uniformly. The penetrant shall remain onthe surface for ten (10) minutes minimum and thirty (30) minutes maximum beforeremoving the excess.

6.6 After the penetration dwell time has elapsed, remove excess penetrant by wiping withclean lint-free absorbent paper or cloth. Clean until only a slight visible trace ofpenetrant remains. Final removal shall be accomplished by wiping with a clean lint-free absorbent paper or cloth that has been slightly dampened with the cleaner.



Page 4 of 4

Allow the surface to dry for at least one (1) minute after all visible traces of the cleanerhave evaporated, but no more that ten (10) minutes, before applying the developer.Note: Do not flush or spray area of interest with cleaner.

6.7 After the cleaned surface has dried for the specified time, apply the developer in a lighteven coat. Excessive wetting or pools of the developer in depressions or cavities isprohibited. (When using an aerosol can for application, thoroughly shake the can untilthe agitator rattles. Invert spray can and spray short bursts to clear valve. Hold spraycan 8 to 12 inches from surface, press spray button straight down and apply a light andslightly wet developer coating.)

7.0 EVALUATION

7.1 During the application of the developer, observe the test area to monitor indications

that have excessive bleed-out. Note the location and size of these excessive bleed-outindications to allow for interpretation of the true size and type of discontinuity.

7.2 The final examination shall be performed after a minimum of ten (10) minutes, but nolonger than sixty (60) minutes. The light intensity requirements per Section V paragraphs T-

676.3 and T-777.1 are satisfactory using a ‘Mag Lite” at a maximum distance of 24”.

7.3 When welds are examined, a minimum of 1 inch or either side of the weld shall beevaluated.

7.4 All indications shall be evaluated in terms of the acceptance standards of the referencecode which is given on each shop drawing. Any additional or special requirementswill be given on the Job Procedure Sheet.

7.5 The shape and size of objects to be examined are not limited to factors, provided thespecified area under examination can be properly examined within the specified timeintervals of this procedure.

7.6 Broad areas of fluorescence or pigmentation which could mask indications ofdiscontinuities are unacceptable, and such areas shall be cleaned and re-examined

7.7 ASME Section VIII, Appendix 8 Para 8-3. An indication of an imperfection may belarger than the imperfection that causes it; however, the size of the indication is thebasis for acceptance evaluation. Only indications with major dimensions greater than1/16”. Shall be considered relevant.(a) A linear indication is one having a length greater than three times the width.(b) A rounded indication is one of circular or elliptical shape with a length equal to or

less than three times its width.



Page 5 of 5

(c) Any questionable or doubtful indications shall be reexamined whether they arerelevant.

7.8 ASME B31.1 Chapter VI, Paragraph 136.4.4 Liquid Penetrant Examination (A) (A.3).Relevant indications are those which result from unacceptable mechanical

discontinuities. Linear indications are those indications in which the length is morethan three times the width. Rounded indications are indications, which are circular orelliptical with the length less than three times the width.

7.9 ASME B31.1 Chapter VI, Paragraph Liquid Penetrant Examination 136.4.4 (A) (A4).An indication of a discontinuity may be larger than the discontinuity that causes it;however, the size of the indication and not the size of the discontinuity is the basis ofacceptance or rejection.

7.10 ASME B31.3, Chapter I, Paragraph 300.2 Definitions

7.10.1 Indication, Linear: In liquid Penetrant examination a closed surface areamarking or denoting a discontinuity requiring evaluation, whose longestdimension is at least three times the width of the indication.

7.10.2 Indication, Rounded; In liquid Penetrant examination a closed surface areamarking or denoting a discontinuity requiring evaluation, whose longestdimension is at least three times the width of the indication.

7.11 Rejectable indications shall be recorded. As a minimum, the type of indications (linearor rounded) , location and extent (length and diameter or aligned) shall be recorded.

8.0 DOCUMENTATION

For each examination, the following information shall be recorded:

(a) Procedure identification and revision;(b) Liquid Penetrant type ( visible);(c) Type ( number or letter designation of each Penetrant, Penetrant Remover,

and Developer used;(d) Examination personnel identity and, qualification level;(e) Map or record indications when required by ASME Section V, T-691;(f) Material;(g) Lighting equipment;(h) Date and time examination were performed.

9.0 POST CLEANING



Page 6 of 6

Upon completion of the penetrant examination, all traces of penetrant and developer shall beremoved from the surface using the Penetrant Cleaner. Deionized water may be used as analternate post cleaner solution for nickel base, austenitic stainless, or titanium materials. Tapwater may be used on all other materials.
