U.L. Certification Markings

1. It is very important that the applicable fire codes are strictly adhered to. The only way to assure compliance is to require that the panel manufacturers provide proof of this fire-rated classification from an independent testing agency like Underwriters Laboratories (U.L.) or equal testing agency.
2. To assure continuous code compliance, the panel manufacturing company must participate in an on-going follow-up service program which is provided and conducted by the independent testing agency. This provides assurance that all fire-rated procedures are strictly adhered to for fire code compliance.
3. Product Markings – to assure that the panels are manufactured in accordance with the applicable fire codes, it should be mandatory that the designing firm or general contractor require a classification sticker to be adhered on the back of every wall panel being installed.
4. Custom Plastics selected U.L. to accomplish all of our fire testing for our various fire-rated classifications. These are available on request or on the U.L. web site referred in Part 2, section 2.1.A which they maintain.
5. Custom Plastics participates in the U.L. Follow-Up Service Program, which assures continual code compliance in our manufacturing procedures.
6. Custom Plastics applies a U.L. approved sticker to the back of every wall panel to assure that code compliance is being met. We ask that you look for this sticker while inspecting the job site to assure you are getting what is required.
