Penetrant Testing

Penetrant testing (PT) is an easy-to-use non-destructive testing method. Penetrants with low surface tension and high capillary effect are used. This allows them to easily penetrate openings in the test part surface such as surface pores or fine cracks with gap widths in the µm range (≥ 25 µm).



Colour contrast penetrant testing of a bearing ring



Fluorescent penetrant testing of a bearing ring



Typical indications that can be detected with the penetrant testing are:

  • Cold cracks
  • Hot cracks
  • Grinding cracks
  • Gas pores and clustered porosities
  • Spongy texture
  • Stress corrosion cracking

Depending on which penetrant is used, a distinction is made between three methods according to EN ISO 3452 Part 2:

  • TYPE I Fluorescent Penetrant Testing
  • TYPE II Colour Contrast Penetrant Testing
  • TYPE III Fluorescent Colour Contrast Penetrant Testing

The basic standard for penetrant testing EN ISO 3452 Part 1 describes in detail how to perform penetrant testing with the various testing products systems.

Process steps of the colour contrast penetrant testing

In the following, the essential steps in performing colour contrast penetrant testing using the red-white method are presented. A solvent-based wet developer (form e) is used.

(1) Precleaning

Mechanical pre-cleaning -
Brushing, grinding, blasting

Precleaning ensures that the surface of the test object is free of contaminants. Impurities can be e.g.: rust, grease or scale. Any indications that may be present are thus made accessible for penetration by the penetrant. Precleaning can be performed:

  • mechanically - e.g. brushing, grinding, blasting
  • chemical - by means of cleaning agents, whereby these must be removed from the surface after the cleaning process

(2) Application of the penetrant (penetration)

Penetrate -
Uniform application of the coloured (or fluorescent) penetrant

The penetrant is sprayed onto the dry surface to be tested. The penetrant can also be applied with a brush. Or the test object is poured over with or immersed into the penetrant. The penetration time can be 5 minutes - 60 minutes. This depends on the test conditions (e.g. temperature) and the test object material .

(3) Excess penetrant removal

Removal of excess penetrant, e.g. with a sponge

During excess penetrant removal, the excess penetrant is carefully removed from the test object surface after the specified penetration time. A lint-free cloth or sponge is used for this purpose. The test surface is carefully inspected for residues.

(4) Drying

Drying the test object surface with moving air

Before the developer can be applied, the test object surface must be dry (except when using a water-based developer, form b and c). This is achieved by:

  • Wiping with a dry lint-free cloth
  • Evaporation
  • Forced ventilation (e.g. hair dryer, compressed air)

(5) Application of the developer

Uniform spraying of the white developer

The developer is applied evenly to the test object surface. A thin, homogeneous, white layer is formed. This ensures that the penetrant remaining in the surface openings is bleeding out.

(6) Inspection

Inspection of the test object surface, indications "bleed" out

Immediately after application of the developer, the test object surface is inspected according to the given inspection intervals. The required viewing conditions (see EN ISO 3059, ASTM E1417 or customer specification) are observed.

The test result and the test conditions are recorded by the NDT personnel in the test report. Depending on the test instruction or specification, documentation by fotos or video recordings are made.

Classification of penetration systems according to EN ISO 3452 Part 2

Testing products for penetrant testing are classified by

  • Type of penetrant
  • Method of excess penetrant removal
  • Form of development

(see EN ISO 3452-2 Table 1 above)

Fluorescent penetration systems are classified according to sensitivity levels starting with ½ (very low) to 4 (ultra-high sensitivity).

There are two sensitivity classes for color contrast penetration systems and fluorescent color contrast penetration systems:

Sensitivity class 1 normal
Sensitivity class 2 high

NORD-TEST

More information

NORD-TEST testing products are used in areas such as

  • Mechanical Engineering
  • Automotive industry
  • Shipbuilding
  • Vessel construction
  • Metalworking
  • Welding technology

Temperature range from -5°C to +50°C.

At low temperatures (from -5 °C to +10 °C), the penetration times must be extended accordingly to achieve the same test sensitivity.

The special specifications in EN ISO 3452-6 "Non-destructive testing - Penetrant testing - Part 6: Penetrant testing at temperatures below 10 °C" shall be taken into account.

For tests at higher temperatures (from +65 °C to +180 °C), the SUPER-CHEK colour penetration system was developed.

The NORD-TEST Penetration System is tested and approved according to

  • EN ISO 3452-2
  • KTA (Kerntechnischer Ausschuss - Nuclear Safety Standards Commission)

and meets the requirements of

  • Lloyd's Register of Shipping
