INSPECTION 6.1.1 6.1.1
Surf ace Preparati on
a) Prior to all liquid penetrant inspections, inspections, the surface to be examined and all adjacent areas within at least 25mm (1 in) shall be dry and free of dirt, grease, lint, scale, welding flux, weld spatter, oil and other extraneous matter that could obscure surface openings or otherwise interfere with the examination. b) Typical cleaning agents that may be used are detergents, organic solvents, and descaling solutions and paint removers. Degreasing and ultrasonic cleaning methods may also be used. c) After cleaning, drying of the surfaces to be inspected shall be accomplished by normal evaporation or with forced hot air, as appropriate. A minimum of 3 minutes drying time shall be given to ensure that the cleaning solution has evaporated before application of the penetrant. d) A minimum of 1000 lux* is required to ensure adequate sensitivity during the examination & evaluation of indications. indications. (*Note. 1000 lux can be achieved with a 100 W lamp, in a distance of less than 600mm from the testing area/surface.) area/surface.)

Appl icatio n of the Penetrant Penetrant
a) After the area has been cleaned, dried and the temperature of the surface and penetrant are within the range of 50 to 125°F (10 to 52°C) b) The penetrant shall be sprayed directly to the surface to be inspected by the means of an aerosol container, such that the entire part of area under inspection is completely covered with penetrant. c) After application, excess penetrant shall be allowed to drain from part (care being taken t aken to prevent pools of penetrant forming on the part), while allowing for proper penetrant dwell time. d) Dwell time shall be in accordance with ASME Section V, SE-165, Table 2, Dwell Times, and Penetrant. e) All dwell times given are those recommended as minimum. f) Maximum penetrant dwell time shall be 60 minutes. g) After the specified penetrant dwell time has elapsed, any penetrant remaining on the surface shall be removed with a dry or slightly moistened cloth of solvent cleaner, taking care to minimize removal of penetrant from any possible discontinuity. h) Flushing the surface with solvent cleaner, following the application of the penetrant and prior to developing is prohibited. i) Drying process (on removal of all excess penetrant and prior to application of the developer).

INTERPRETATION
All indications shall be considered considered as discontinuities discontinuities until investigated, upon investigation such indications shall be recognized as weld or material related and relevant, therefore subject to interpretation in accordance with the clients governing specification with regard to accept/reject criteria. For piping the acceptance criteria shall be ASME B 31.1 or ASME B 31.3 whichever is applicable. ASME Sec.VIII Div.1 App.8* App.8* [*This shall apply unless more restrictive standards are specified for specific materials or applications within ASME Sec VIII Div.1 All surfaces to be examined examined shall be free of;
Relevant linear indications Relevant rounded indications greater than 3/16 inch(4.8mm) Four or more relevant rounded indications in a line separated by 1/16 inch (1.6mm) or less edge to edge.
