Material name
1906 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Acid, sludge” and “Sludge acid”. Both use Guide 153, so the number alone is enough to find the guide. On a numbered orange panel, 1906 is the lower number (how to read an orange panel).
