The P-MET PMC FLAWCHECK Dye Penetrant Inspection Kit is a professional-grade NDT system that detects surface defects as small as 1 micron. This solvent-removable kit includes PP-110B red penetrant, PC-120B cleaner, and PD-130B developer in 400ml aerosol cans.
Certified to ASTM E1417, ASME Section V, and ISO 3452 standards with NPCIL, DGCA, and DGAQA approvals. Ideal for aerospace, nuclear, automotive, and industrial applications requiring precision flaw detection of cracks, porosity, and surface discontinuities.
What is the PMC FLAWCHECK Dye Penetrant Inspection Kit?
The PMC FLAWCHECK 3-Digit Series is a complete liquid penetrant testing (LPT) system engineered for non-destructive examination of non-porous materials. Liquid penetrant inspection is one of the most widely used NDT methods for detecting surface-breaking defects that may not be visible to the naked eye, including fatigue cracks, stress fractures, porosity, cold shuts, and lack of fusion.
Unlike ultrasonic or radiographic testing, dye penetrant inspection works on the principle of capillary action—the penetrant is drawn into surface openings, then highlighted using a contrasting developer to create a visible indication of the defect’s size and location. This makes it ideal for field inspections, in-process quality control, and maintenance examinations where portability and rapid results are essential.
How PMC FLAWCHECK Works
The three-component system operates through a controlled sequence:
- Surface Preparation: The test surface is cleaned using PC-120B solvent cleaner to remove contaminants such as oil, grease, dirt, and oxidation that could block penetrant entry
- Penetrant Application: PP-110B visible red penetrant is applied and allowed to dwell, enabling capillary forces to draw the liquid into surface-breaking discontinuities
- Excess Removal: Excess penetrant is carefully removed from the surface using the solvent remover, without extracting penetrant trapped within defects
- Development: PD-130B developer is applied, acting as a blotter to draw out trapped penetrant and create high-contrast indications
- Inspection: Defects appear as bright pink-red indications against the white developer background under normal daylight or white light
This systematic approach ensures consistent, repeatable results across diverse materials including metals, ceramics, glass, and certain plastics.
Why This Matters for Critical Applications
In aerospace, nuclear power, petrochemical, and automotive industries, undetected surface defects can lead to catastrophic failures. A hairline crack in a turbine blade, a stress fracture in a weld, or porosity in a casting can compromise structural integrity and safety. PMC FLAWCHECK provides quality assurance teams, MRO facilities, and manufacturing plants with a reliable, cost-effective method to verify component condition before parts enter service or return to operation after maintenance.
The kit’s sensitivity to detect defects as small as 1 micron width × 20 micron depth on standard Ni-Cr test panels makes it suitable for the most demanding inspection requirements. This level of detection capability is critical when inspecting high-value components where even microscopic flaws could propagate under stress or thermal cycling.

Operating Principle
Liquid penetrant testing exploits the physical property of capillarity—the ability of liquids to flow into narrow spaces without external forces. The penetrant’s low surface tension and high wetting ability allow it to enter defects with openings as small as 1 micron. After excess surface penetrant is removed, the developer’s reverse capillary action draws trapped penetrant back to the surface, creating an indication larger than the actual defect for enhanced visibility.

How to Use – Step-by-Step Inspection Procedure
Pre-Inspection Preparation
Step 1: Surface Cleaning
- Spray PC-120B cleaner onto the inspection surface
- Remove all oil, grease, dirt, rust, paint, scale, and other contaminants
- Allow surface to dry completely (2-5 minutes)
- Ensure surface is at room temperature (15-50°C / 60-120°F)
Important: Inadequate surface preparation is the #1 cause of missed defects. The surface must be completely clean and dry for penetrant to enter defects.
Penetrant Application
Step 2: Apply Penetrant
- Shake PP-110B can vigorously for 30 seconds
- Hold can 20-30 cm (8-12 inches) from surface
- Apply uniform wet coat covering the entire inspection area
- Ensure complete coverage without excessive pooling
Step 3: Dwell Time
- Allow penetrant to dwell: 5-30 minutes depending on material and defect type
- Minimum 5 minutes: Most metals at room temperature
- 10-15 minutes: Tight cracks, cold materials
- 20-30 minutes: Deep defects, rough surfaces
- Keep surface wet during dwell; reapply if penetrant dries
Penetrant Removal
Step 4: Remove Excess Penetrant
- Spray PC-120B cleaner onto clean, lint-free cloth (not directly onto part)
- Wipe surface gently to remove excess penetrant
- Continue wiping until surface appears clean (faint pink stain acceptable)
- Critical: Do not over-clean; this can remove penetrant from defects
Developer Application
Step 5: Apply Developer
- Shake PD-130B can well to mix suspended powder
- Hold can 30-40 cm (12-16 inches) from surface
- Apply thin, uniform white coating
- Allow developer to dry (5-10 minutes)
Inspection & Interpretation
Step 6: Visual Examination
- Inspect surface under good lighting (minimum 500 lux / 50 foot-candles)
- Look for bright pink-red indications against white background
- Relevant indications will:
- Bleed out gradually (not appear instantly)
- Have distinct edges and defined shapes
- Grow in size over 5-10 minutes
Indication Types:
- Linear indications: Cracks, laps, seams
- Rounded indications: Porosity, pits
- Broad, irregular: Surface roughness, non-relevant indications
Step 7: Documentation
- Photograph or mark indication locations
- Measure indication dimensions
- Compare against acceptance criteria (per drawing or code requirements)
Post-Inspection Cleaning
Step 8: Final Cleaning
- Remove developer coating with PC-120B cleaner
- Clean surface thoroughly to prevent contamination
- Dispose of used materials per local regulations
