Multiple Choice

Foam solution fittings shall be which of the following materials?

Fittings for foam solution must be compatible with the foam concentrate and the system, and the right material is determined by approval. Because foam concentrates can be corrosive or reactive with certain metals, the standard allows using any material that has been approved by the Authority Having Jurisdiction or by the system manufacturer. This ensures the chosen material is proven to resist corrosion and not interfere with foam performance for that particular setup. So the correct choice is the one that states the material must be approved by the AHJ or manufacturer.
