HDPE Toilet Partitions-Is there a fire rating requirement
Most the building safety codes require the materials for the interior wall finishes to be tested for flame spread and smoke development per ASTM 84E. I am not sure about fire rating?
The following codes and standards require that when HDPE is used as an interior finish, it must be tested in accordance with and to comply with NFPA 286 Standard Methods of Fire Tests for Evaluating Contribution to Wall and Ceiling Interior Finish to Room Fire Growth.
NFPA 286 describes a method for determining the contribution of interior finish materials to room fire growth during specified fire exposure conditions. It is intended for the evaluation of the flammability characteristics of wall and ceiling interior finish, other than textile wall coverings, where such materials constitute the exposed interior surfaces of buildings.
ASTM E-84 Standard Test Method for Surface Burning Characteristics of Building Materials is insufficient when testing plastics that melt and fall to the floor of the ASTM E-84 tunnel. NFPA 286 is the preferred testing method because it is superior at determining the hazard of an interior finish.
Based on fire research, no HDPE toilet partition manufacturer should be citing flame spread performance using ASTM-E84.

I believe this NFPA 286 ASTM E-84 requirement for toilet partitions is only required when your restroom is not separated from an egress corridor.
