Steps

Confirm ASTM C1629/C1629M classifies abuse-resistant nondecorated interior gypsum panels into Level I, II, or III based on four test methods: ASTM D4977 surface abrasion, ASTM D5420 surface indentation, Annex A2 soft-body impact, and Annex A1 hard-body impact
Match the required level to the space's actual risk profile (Level I for moderate-traffic corridors, higher levels for detention or heavy-impact areas) using a manufacturer's published usage guide as a practical translation of the ASTM classification
Purchase the full ASTM C1629 text from store.astm.org if the spec requires citing exact test values rather than just relying on manufacturer summaries
Confirm the selected product's specific ASTM C1629 classification level from its data sheet, since 'abuse-resistant' is a marketing term that must map to a tested level to be enforceable in a spec
Check whether ASTM C1658 (glass mat gypsum panels) applies instead/in addition if the board is glass-mat faced for moisture or mold resistance in the same area

Known gotchas

ASTM C1629 itself is a paywalled standard (store.astm.org); manufacturer blog summaries (e.g., National Gypsum's 'ngconnects' articles) are useful for translation but are not a substitute when a spec requires literal ASTM citation
'Abuse-resistant' or 'impact-resistant' as marketing language doesn't guarantee a specific classification level -- always confirm the tested Level I/II/III rating on the actual product data sheet
