Is certification to UL499 standard required?

• The ultimate authority 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 plan to buy a kiln 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, institutional, and sometimes industrial buildings.
