Material name
1984 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Refrigerant gas R-23” and “Trifluoromethane”. Both use Guide 126, so the number alone is enough to find the guide. On a numbered orange panel, 1984 is the lower number (how to read an orange panel).
ERG 2024 markings for 1984
1984 is not highlighted in green (no Table 1 entry), and its guide number 126 has no P.
