3.7 inclusions
non-metallic particles originating from the material manufacturing process
NOTE These particles may be isolated or arranged in strings.
3.8 critical detect
defect that, according to judgement and experience, is likely to result in hazardous or unsafe conditions for individuals using, maintaining, or depending upon the considered product, or that is likely to prevent performance of the function of a major end item
3.9 major defect
defect, other than critical, that is likely to result in a failure or to reduce materially the usability of the considered product for its intended purpose
3.10 minor defect
defect that is not likely to reduce materially the usability of the considered product for its intended purpose, or that is
a departure from established specifications having little bearing on the effective use or operation of this product.ISO 5858 pdf download.
