    is certification to uL499 standard required?

    • The ultimate authority for this is a local authority such as a local code official.
    • Usually it is not a requirement but this does vary from jurisdiction to jurisdiction.
    • If you are planning to buy a kiln that is not listed to UL499 standards you should check with your local code inspector to be certain.
    • Generally speaking this is only a requirement in public or institutional and sometimes industrial buildings.
