(referred to as Plates) that categorize discontinuities by type and severity: GlobalSpec Plate 1: Linear Discontinuities – Covers cracks and other elongated surface flaws. Plate 2: Shrinkage and Inclusions
, there is a significant technical caveat. ASTM International traditionally produces these reference photographs as high-quality, physical photographic glossies. This is because digital compression in a standard PDF can obscure the fine details of a magnetic particle indication, potentially leading to misinterpretation.

The standard provides a common language for manufacturers and purchasers to agree upon "severity levels" for a casting. For example, a high-stress component might require a stricter severity level (fewer visible indications) compared to a non-structural part. Classification of Discontinuities
