Annex 4.

The minimum penetration time shall be as required in Table T or as qualified by demonstration for specific applications.

ASME v Article 6 Liquid Penetrant Examination

The water pressure shall not exceed 50 psi kPa. Excess waterwashable penetrant shall be removed with a water spray. After the required penetrant dwell time and prior to emulsification. Emulsification time is dependent on the type of emulsifier and surface condition.

T Penetration Dwell Time Penetration dwell time is critical. After the required penetrant dwell time. If meters have not been in use for one year or more.

V article 6 asme pdf section

The actual emulsification time shall be determined experimentally. After pre-rinsing. Excess Penetrant Removal After the specified penetration dwell time has elapsed. To minimize removal of penetrant from discontinuities.

Flushing the surface with solvent. The remaining traces shall be removed by lightly wiping the surface with cloth or absorbent paper moistened with solvent. Bath concentration shall be as recommended by the manufacturer. With color contrast penetrants. With fluorescent penetrants. Blotting is not permitted. Inadequate cleaning may leave an excessive background making interpretation difficult.

The examination shall be performed as follows: Nonaqueous developers shall be applied by spraying. Aqueous developer may be applied to either a wet or dry surface.

Drying time may be decreased by using warm air. Indications with a light pink color may indicate excessive cleaning. Prior to applying suspension type wet developer to the surface.

If bleed-out does Post-Examination Cleaning When post-examination cleaning is required by the procedure. If the surface to be examined is large enough to preclude complete examination within the prescribed or established time.

Article 6 pdf section v asme

Dry developer shall be applied only to a dry surface by a soft brush. Developing time for final interpretation begins immediately after the application of a dry developer or as soon as a wet developer coating is dry. Insufficient coating thickness may not draw the penetrant out of discontinuities.

A minimum light intensity of fc lx is required on the surface to be examined to ensure adequate sensitivity during the examination and evaluation of indications. For water-washable or post-emulsifiable penetrants. Surface discontinuities are indicated by bleed-out of the penetrant which is normally a deep red color that stains the developer. It shall be applied by dipping.

The type of discontinuities are difficult to evaluate if the penetrant diffuses excessively into the developer. T 10 T Interpretation T The light source. Glasses or lenses worn by examiners shall not be photosensitive.

Drying shall be by normal evaporation. Developing The developer shall be applied as soon as possible after penetrant removal. Under such conditions. Cracked or broken filters shall be replaced immediately. For solvent removable penetrants. With a color contrast penetrant. Final interpretation shall be made not less than 10 min nor more than 60 min after the requirements of T If this condition occurs.

Rejectable indications shall be recorded. Nonrejectable indications shall be recorded as specified by the referencing Code Section. As a minimum. Annex 4. Annex 2 for chlorine and SE Techniques for Standard Temperatures.

When this Article is speci? Typical discontinuities detectable by this method are cracks, seams, laps, cold shuts, laminations, and porosity.

In principle, a liquid penetrant is applied to the surface to be examined and allowed to enter discontinuities. All excess penetrant is then removed, the part is dried, and a developer is applied.

The developer functions both as a blotter to absorb penetrant that has been trapped in discontinuities, and as a contrasting background to enhance the visibility of penetrant indications.

These records shall be maintained as required by the referencing Code Section. T Surface Preparation T Liquid penetrant examination shall be performed in accordance with a written procedure which shall as a minimum, contain the requirements listed in Table T The written procedure shall establish a single value, or range of values, for each requirement.

Surface preparation? Degreasing and ultrasonic cleaning methods may also be used. The cleaning method employed is an important part of the examination process. Conditioning of surfaces prior to examination as required in T a may affect the results. Form c - Water Suspendable 4.
