ASTM standards are copyrighted materials. While ASTM allows "single copies for individual use" in some educational contexts, distributing a free, full-resolution PDF of the reference photographs without a license is copyright infringement. More importantly, low-resolution scans are dangerous . If you cannot distinguish between a Level 2 shrinkage and a Level 3 shrinkage, you might reject a good part (or worse, accept a bad part).
Prepare the ferrous casting surface and apply the magnetic field along with wet fluorescent or dry visible magnetic particles.

Magnetic Particle Testing (MT) is a cornerstone of non-destructive testing (NDT) for finding surface and near-surface flaws in ferromagnetic materials. When inspecting steel castings, technicians often see complex visual indications.
Fractures formed during the cooling process as the metal shrinks under tension.

Many modern NDT labs, engineering firms, and quality managers seek the text for fast digital access to the standard's guidelines, scope, and terminology.

The primary "documents" for E125 are the actual photographs (adjuncts). While the standard text explains the methodology, the is required to perform the comparison.
Chaplets are metal supports used to hold cores in place inside a mold. Chills are metal inserts used to speed up cooling in thick sections. If these components do not completely fuse with the poured molten metal, their boundaries appear as distinct magnetic particle patterns. Type V: Porosity
: Maintain a minimum of 100 foot-candles (1076 lux) for visible particles, or use a black light with a minimum intensity of 1000 µW/cm² for fluorescent particles.
