steel, martensitic stainless steel, titanium and nickel base alloys.

3.1.2 Manufacturing Process Welded joints, Casting or Forging components.

3.2 PERSONNEL QUALIFICATION

3.2.1 Personnel performing and interpreting Liquid Penetrant Testing shall be ASNT SNT-TC- lA Level II or Level III or PCN Level II Personnel.

3.2.2 Reports shall only be reviewed and signed by PCN Level II or ASNT Level III personnel.

3.3 PRODUCT TO BE USED

Liquid penetrants used are visible penetrant using the solvent-removable process.

3.3.1 Only products within their validity terms shall be used, as well as having their sensitivity proved by tests upon being received, as per

Item 3.11.2.

3.3.2 In austenitic stainless steel and titanium inspection, only shall be used those penetrants having chemical analysis certificates in respect to the contaminant content (chlorine and fluorine), that shall not exceed values, prescribed in Item 3.3.2.1 and 3.3.2.2.

3.3.2.1 When examining austenitic or duplex stainless steel and titanium, all penetrant material, the total halogens content shall not exceed 1% by weight in accordance with SE-165, Annex 4 (2010 edition)




3.3.2.2 The summation of the chlorine and fluorine contents shall not exceed 1% by weight in accordance with SE-165 Annex 2 for chlorine and Annex 3 for fluorine.

3.3.3 In inspection of nickel base alloys, only those penetrants having chemical analysis certificates in respect to the contaminant content

(sulphur) shall be used, which shall not exceed the value prescribed in 3.3.3.l .and 3.3.3.2.

3.3.3.1 When examining nickel base alloys, all penetrant materials, for sulphur content shall not exceed 1% by weight in accordance with SE-165 Annex 4.

SAMPLE OF LIQUID PENETRANT MATERIAL

Penetrant Ardrox 996 or parameter of Spotcheck SKL-HF/S Cleaner Ardrox 9PR551 or Spotcheck SKC-S Developer Ardrox 9D6 or Spotcheck SKD-S2

Others equivalent brand shall be used but no inter-mixing of brand types.

The material selected conform to the requirements of MIL-25135 and DTD 929, being non-flammable having a low toxicity and being essentially free of all Sulpurs, Sodium compounds, Chlorides and Potential ash- forming

residues.

3.4 SURFACE PREPARATION

3.4.1 Surfaces to be inspected and 25mm of an adjacent area shall be clean from grease, oil, oxides, dripping, slag, etc. Mechanical cleaning by wire brushing or grinding shall be performed, followed by solvent cleaning.

NOTE: When inspection is to be done on stainless steels, tools shall be made from Stainless steel or coated with this material; brushes shall be

made from stainless steel and cutting discs shall have a nylon core or similar. These tools shall be used exclusively on stainless steels.

3.4.2 Drying Method and Time

3.4.2.1 Drying method: normal evaporation 3.4.2.2 Drying Time : >5 minutes




3.5 LIQUID PENETRANT APPLICATION METHOD AND PENETRATION TIME

3.5.1 Application shall be done by aerosol, spraying or by brushing.

3.5.2 The penetration time shall be at least 5 minutes: it shall never be greater than 10 minutes. The minimum penetration time shall be as required

in ASME Section V minimum dwell times table or as per client Specification; or as qualified by demonstration for specific applications.

3.6 TEMPERATURE RANGE FOR INSPECTION

3.6.1 Both the surface and penetrant materials are to be in a temperature range between 5°C and 52°C during the whole inspection.

3.7 METHOD FOR REMOVING THE LIQUID PENETRANT EXCESS

3.7.1 For solvent removable penetrant, the excess is to be first removed with dry and clean cloths. After this first cleaning, cloths slightly moistened in

cleaner shall be used. Cleaner products shall not be applied directly on the test piece.

3.8 DRYING METHOD AND TIME, BEFORE APPLICATION OF THE DEVELOPER

3.8.1 Drying method: normal evaporation

3.8.2 Drying time: > 5 minutes

3.9 METHOD AND MAXIMUM TIME FOR APPLICATION OF THE DEVELOPER

3.9.1 The developer shall be applied by aerosol spraying immediately after drying of the surface and in a 30-minute maximum period after finishing the removal of the excess.

3.10 TIME FOR INTERPRETATION

3.10.1 The initial interpretation shall be done immediately after application of the developer.

3.10.2 The final interpretation shall be done not less than 10 minutes nor more than 60 minutes after application of the developer.




3.11 ADDITIONAL REQUIREMENTS

3.11.1 The minimum illumination during the whole examination by liquid penetrant shall be 1000 lux (100fc).

3.11.2 Testing penetrant materials upon being received

3.11.2.1 Only those penetrant materials containing on their packages the manufacturing date, the validity term and the lot

manufacturing number shall be accepted.

3.11.2.2 For each lot received testing shall be performed, in order to check whether the testing sensitivity is maintained. The test

when receiving shall be performed by using the Magnaflux Corporation Test Panel Z5 that complies with Pratt & Whitney

TAM 146040. At least four indications should be visible when the panel is used. Test result shall be documented. Only those materials with sensitivity equal or greater than that shown in the block shall be accepted.

3.12 FLOW DIAGRAM FOR PENETRANT FLAW DETECTION, INTERPRETATION AND RESULT ASSESSMENT




3.13 INTERPRETATION OF INDICATION

3.13.1 Interpretation shall be made at intervals during the "bleed out" process so that large indication may be viewed before excessive

diffusion occurs.

3.13.2 Indication shall be classified as "false", "irrelevant", or "relevant".

"False" cause by poor washing or cleaning during removal of excess penetrant process.

"Irrelevant" cause by localize surface imperfections such as machining marks, surface conditions or an incomplete bind between base metal and cladding.

"Relevant" indication are those which result from mechanical discontinuities.

3.13.3 Linear indications are those indications in which the length is three times more than the width. Only indication with major dimensions greater than I/16 in. (1.6mm) shall be considered relevant.

3.13.4 Rounded indications are indications, which are circular or elliptical shape with length equal to or less than three times the width.

3.13.5 Any questionable or doubtful indications shall be retest to verify whether or not actual defects are presents.

3.13.6 Any assessment of result shall be in accordance to Item 3.14




3.14 RESULT ASSESSMENT CRITERION

This criterion for assessing results shall be in accordance to client as specified in their material specification or contractual documents for

Acceptance and Rejection.

This assessment criterion shall be as per one of the following specification requirement : -

3.15 FINAL CLEANING

It shall be done with a hand brush, industrial cleaning cloths and solvent. For stainless steels and nickel base alloys, take into account items 3.3.2 and 3.3.3

3.16 SAFETY

Refer to QP – 18 Safety.
