How are SnagPod specimens assessed?

After testing, SnagPod specimens are graded from 1 to 5 to the nearest half a grade for appearance, in a viewing cabinet using the descriptions in BS 8479.

SnagPod reference photographs (set of 9) may also be used for comparison to aid grading in the viewer.

ProView – exclusive to James Heal - is pre-loaded with SnagPod reference photographs for easy assessment.


In addition, the type/s of surface defects should be classified according to the 8 descriptions in BS 8479 (A to G and X).

James Heal can supply the following for assessment of SnagPod specimens:
