E tusa ai ma le "Classification of Combustion Performance of Building Materials and Products" a Saina (GB 8624-2012), Vasega A mea e le mafai ona mu. Ole fua ole afi ole laupapa lagolago e faalagolago ile mea:
- Vasega A laupapa lagolago: laupapa gypsum, laupapa magisa tioata, laupapa fulufulu ma'a, ma isi, fa'ata'ita'iina ma fa'amaonia o le Vasega A1 (e le-mu) po'o le Vasega A2 (maualalo-asu, le-mu). Mo se fa'ata'ita'iga, sa fa'ata'ita'iina e le Vasega A1 se fa'ailoga tioata tioata e lagolago ai laupapa (fa'asino: National Fireproof Building Materials Quality Supervision and Inspection Center report).
- E le o le Vasega A laupapa lagolago: Ordinary density fiberboard ma plywood e masani lava Vasega B2 (mu) po'o le Vasega B1 (faigata ona mu), e mana'omia le fa'aopoopoina o mea e fa'afefe mu e fa'aleleia ai le fa'atatau.
