| dcterms_is_replaced_by | 1 | pipeline.collision_decisions | merged onto 4d9a8790-3ddd-11dd-925b-0050c2490048 by curator ruling: Urban air close to ground level. Seven factors each side. EF 3.1 publishes 1,1,1-trichloroethane twice in each of four air compartments, once as `HCFC-140` -- its refrigerant code -- and once as `Methyl chloroform`, which is what the degreasing trade called it. Both are real names for the solvent and both copies carry CAS 71-55-6, so nothing is in doubt about what the substance is. The `HCFC-140` copy also carries EC 200-756-3, 57 synonyms and EF's general comment; the other carries none of those, and no source list reaches either. The identified row survives. The factor counts tie in all four compartments, so a sort would fall through to the identifier, and in unspecified air it would keep the bare row. Both names are already published as one -- `preferred-label-decisions.json` refuses `1,1,1-Trichloroethane` -> `HCFC-140` and approves `Methyl Chloroform` -> `1,1,1-Trichloroethane` -- which is what left nothing but a free-text comment telling the two rows apart (#530). |
