The standard categorizes indications into several distinct types based on their physical characteristics and origin. These include:
Reference photographs rely on high-fidelity visual reproduction. Compressed, scanned, or photocopied PDFs often destroy the resolution required to see the fine detail of magnetic particle indications, rendering them useless for actual inspection. astm e125 reference photographs pdf free download
