Applied dye penetrant testing as per ASTM E165-18 to detect surface discontinuities and cracks in materials

Aimed to identify surface defects on a spring, a round bar, and a distributor cap

Followed ASTM E165-18 procedures for liquid penetrant testing

Applied liquid penetrant to specimens, allowing capillary action to draw it into flaws

Removed excess penetrant and applied developer to draw trapped penetrant to the surface, creating visible indications

Utilized Magnaflux Visible Penetrant, Magnaflux Developer, and Magnaflux Cleaning/Removing Solution

The helical compression spring showed no defects, with pink coloration attributed to improper washing

The round bar also exhibited no defects, although excessive developer application led to pink indications and reduced clarity in some areas

The distributor cap revealed multiple surface defects, confirming its non-conformance

The overall lab confirmed the effectiveness of dye penetrant testing for defect detection, particularly for the distributor cap specimen, and obtained an 80% report
