Indications caused by magnetic field variations rather than material flaws. Format & Availability
: You can purchase or access official copies through the ASTM International website or authorized distributors like Accuris Standards Store and BSB Edge . Summary of Document Data
To implement the standard correctly, engineering teams must define the acceptance criteria during the contract review phase. The purchase order should explicitly state the casting zones, the applicable ASTM E125 defect types, and the maximum allowable severity level for each zone. During inspection, the certified Level II or Level III NDT technician views the component under proper lighting conditions, maps the indications, and utilizes the reference photographs to issue a definitive pass/fail report.
: The severity level found is compared against the maximum allowed level specified in the contract or technical drawing. Why Assign Severity Levels? Astm E125 Reference Photographs Pdf
The ASTM E125 reference photographs PDF is a valuable resource for several reasons:
For purchasing the official standard or the photographic adjuncts, it is best to visit the ASTM official website.
: Match the size, concentration, and frequency of the actual indications against the standard photographs. Indications caused by magnetic field variations rather than
Inspection of massive turbine housings, valve bodies, and pump casings.
ASTM E125 categorizes indications into eight distinct types (designated by Roman numerals I–VIII). Most types include five degrees of severity. Steel Founders’ Society of America Discontinuity Category Description Linear Discontinuities
: Used when a specific severity class is agreed upon between a manufacturer and purchaser to determine if a casting is acceptable. iTeh Standards Classification of Discontinuities The purchase order should explicitly state the casting
Quality assurance for structural frames, gears, and mining equipment components.
Each type of discontinuity is categorized into several , usually ranging from Level 1 (least severe) to Level 5 or higher (most severe). Finding the ASTM E125 Reference Photographs (PDF/Adjunct)
Each type of discontinuity in the ASTM E125 reference photo set is further broken down by , typically ranging from 1 (lowest/smallest) to 5 (highest/largest) .
This classification refers to specific, often sharp, magnetic particle indications related to internal cooling methods used during casting.
