MECHANICAL PROTECTION (CUT, ABRASION, PUNCTURE)
CUT
Relevance to the Market:
The new TDM method should correlate with the previous CPPT method, but because of the inherent variability in cut testing, gloves with cut resistance levels that are near a transition value may see a change.
The biggest effect of the new levels will be more segmentation in the old ANSI cut 4 range. Gloves rated level 4 in the old range can be rated A4, A5 or A6
in the new range. The new high-end levels – A7, A8,
A9 – will apply to some food gloves but were created to differentiate high-end cut-resistant gloves.
The new ANSI/ISEA levels harmonize with new EN high cut levels up to level A6/F, but the ANSI/ISEA standard does a better job providing differentiation of high-end cut-resistant gloves above that level, up to 6,000 grams.
