DP55 RED DYE PENETRANT 300ML AEROSOL (PMUC) – Visible Dye Penetrant for NDT

DP55 RED DYE PENETRANT 300ML AEROSOL (PMUC) is a visible red dye penetrant used in liquid penetrant testing to assist in identifying surface-breaking discontinuities in suitable materials.

DP55 belongs to the Type II penetrant category and is classified by the manufacturer as Methods A and C, Level 2 under AMS 2644 and ISO 3452-2.

As a visible dye penetrant, DP55 is used during the penetrant application stage of a non-destructive testing procedure. Its purpose is to enter surface-open discontinuities so that relevant indications can subsequently be revealed using the appropriate developer and inspection conditions.

The product is water-washable and is described by SOCOMORE as resistant to overwashing.

RIO Middle East lists DP55 within its Penetrant Testing product category, alongside cleaners, developers and other specialist inspection materials.

DP55 Product Specifications

The following information identifies the listed 300 ml aerosol configuration.

These characteristics are based on the manufacturer’s published information. Users should refer to the applicable Technical Data Sheet and inspection procedure for operating requirements.

The Role of DP55 in Visible Dye Penetrant Testing

Visible dye penetrant inspection is a non-destructive testing method used to examine suitable, nonporous materials for discontinuities that are open to the surface.

The inspection relies on a penetrant entering accessible surface openings through capillary action.

After the prescribed penetration time, excess material is removed from the surface and the appropriate developer is applied.

The developer helps draw retained penetrant from surface-open discontinuities to form visible indications.

DP55 provides the red penetrant material used during this process.

It is important to distinguish between identifying an indication and determining whether a component is acceptable. Interpretation of indications must follow the relevant inspection standard and acceptance criteria.

DP55 should not be described as detecting subsurface defects that have no opening to the inspected surface.

Key Characteristics of DP55 Red Dye Penetrant

Type II Visible Penetrant

DP55 is classified as a Type II penetrant.

This designation identifies a visible dye penetrant system, distinguishing it from Type I fluorescent penetrants.

The inspection relies on the appearance of visible colour indications under the prescribed viewing conditions.

Water-Washable Formulation

SOCOMORE identifies DP55 as water-washable.

This characteristic is associated with Method A penetrant removal, where water is used to remove excess penetrant according to the approved procedure.

Water-washable does not mean that unrestricted washing is acceptable.

Removal conditions must be controlled to avoid affecting penetrant retained within relevant discontinuities.

Resistance to Overwashing

The manufacturer describes DP55 as resistant to overwashing.

This is a documented product characteristic, but it should not be interpreted as eliminating the possibility of excessive penetrant removal.

Inspection personnel must still follow the prescribed washing procedure and inspection requirements.

Method C Classification

DP55 is also classified for Method C.

Method C refers to solvent-removable penetrant processing using an appropriate solvent-removal procedure.

The selected removal method must correspond to the applicable inspection instructions.

Formulation Information

SOCOMORE identifies DP55 as free from Rhodamine and Azo III A2 amines.

These are specific manufacturer statements concerning the product formulation.

They should not be expanded into broader claims such as non-toxic, hazard-free or environmentally harmless.

Understanding Type II, Methods A and C, Level 2

The technical classifications associated with DP55 help purchasers and inspection personnel identify the appropriate penetrant for a specified inspection system.

A product’s classification does not independently determine whether it is approved for a particular aircraft, component or industrial inspection.

The full inspection system and applicable specification must be verified.

DP55 Within the Penetrant Inspection Sequence

DP55 is the penetrant material used during the second principal stage of a typical liquid penetrant inspection process.

The following overview explains the role of each material without replacing a qualified inspection procedure.

1. Surface Preparation

Before penetrant application, the surface must be prepared according to the relevant procedure.

Cleaning is intended to remove contamination that could prevent penetrant entry into surface-open discontinuities.

RIO Middle East lists DR62 Degreaser/Cleaner 300ML Aerosol as a separate product associated with penetrant inspection cleaning operations.

2. Penetrant Application

DP55 is applied as the visible red dye penetrant according to the inspection procedure.

The prescribed penetration time, surface conditions and application method must follow the approved instructions.

3. Excess Penetrant Removal

After the specified penetration time, excess penetrant is removed using the permitted removal method.

Because DP55 is classified for Methods A and C, the applicable procedure determines whether water washing or solvent removal is appropriate.

4. Developer Application

A compatible developer is applied where required by the inspection system.

The developer assists in producing visible indications from retained penetrant.

RIO Middle East also lists D100 White Developer 300ML Aerosol (PMUC) as a separate penetrant testing product.

5. Inspection and Interpretation

Indications are examined under the viewing conditions required by the relevant procedure.

Qualified personnel interpret the results against the applicable inspection criteria.

6. Post-Inspection Requirements

Any required post-cleaning, recording or component handling must follow the applicable inspection instructions.

DP55, DR62 and D100 – Different Roles in NDT

DP55 is commonly considered alongside cleaning and developer materials when sourcing a penetrant inspection system.

However, the three products perform different functions.

DP55 is not a degreaser, while DR62 is not a penetrant.

Similarly, a developer does not replace the penetrant itself.

Product compatibility, the removal method and the selected developer must be confirmed for the intended inspection procedure.
