Listing and Labeling for IBC Approval

Bill Kreysler, founder of Kreysler & Associates and chair of ACMA’s Architectural Division, has years of experience in the architecture market. As principal scientist at Ashland Company, Mike Stevens is an expert on fire-resistant resins. Together, they talk about FRP and the International Building Code, with Kreysler contributing the first part of this column and Stevens providing details on the steps involved in a listing and labeling program. The International Building Code (IBC) serves as the rule book for construction in the U.S. While there are supplemental codes and some exceptions, the IBC is the base code standard. If your product or process isn't recognized in the code, you’re out of luck. It's like driving without a license: You can do it as long as you don't get caught. But if you ignore the IBC, heaven help you if there's a problem and your work or product is involved. In 2007, ACMA’s Architectural Division decided to “get a license” by petitioning the code council to recognize FRP as a legitimate material for the first time. The result is section 2613 of the current IBC, which defines what FRP is, how it must be made to qualify as a building material and what tests it must pass for various applications. There are a handful of tests recognized by the IBC, but the two biggest are the ASTM E-84 and the NFPA 285, developed by the American Society for Testing and Materials International and the National Fire Protection Association respectively. If a developer wants to cover more than 20 percent of the exterior of certain type buildings over 40 feet tall with FRP, the materials in the thickness specified for the project must be tested and achieve Class 1 ASTM E-84 for both flame and smoke. In addition, the wall assembly – including the exterior skin and whatever is behind it – must pass the NFPA 285 test. Passing the E-84 is easier and less costly than passing the 285. The E-84 is simply a materials test, while the 285 is an assembly test. Therefore, things like joints between panels and the space behind them are critical to passing the 285. (If you’re covering less than 20 percent of an exterior with FRP, there are less stringent tests. Other applications, such as interior walls and ceilings, also require other tests.) When striving to pass building tests, it's not enough to simply use a so-called “Class 1 fire-retardant resin.” There is no such thing in the IBC. To be code compliant, you must test the entire product – glass and resin – at the thickness you intend to use. In addition, these tests must be performed by the company making and providing the product, or be a “sub-listee” of the company that did the test. Finally, the product delivered to the job site must be certified as having been made according to pre-approved quality standards by an IBC-approved independent testing lab and have a label on the product saying so. These labs offer what are called “listing and labeling programs” to fulfill these requirements and ensure that any product that ultimately reaches the end user is similar to the product that was approved during testing. The process involved in participating in a listing and labeling program has many parts. The first step is to identify what applications you want the program to cover. Based on the application, you can then identify the required test methods set forth in the IBC code. If you aren’t sure, consult with a building code official or code consultant. The next step is to pick a listing agency for your product. There are several in North America, including Southwest Research Institute, Intertek and Quality Assurance International. Each of these agencies will work with you to set up the listing and labeling program. One of the tasks they will help with is development of a quality assurance (QA) manual, which inspectors will use when they audit your facility. Another requirement of the listing program is to fabricate the requisite test panels under the eye of an inspector approved by the listing agency. The inspector will label the panels so they can be identified at the testing lab. Afterward, the panels are shipped to the testing lab to undergo the appropriate tests. Once completed, the test reports become part of the listing. The QA manual also includes a description of how the products are made and typical applications for the product. The manual identifies any raw materials used in production of the part, including the resin’s product name. More than one resin can be listed as long as testing is done on each resin being used. Depending on the listing agency, the glass fiber brand and type may also have to be listed. After the listing is complete – with all of the test results and the QA manual – the listing agency will create a time table for follow-up inspections of the shop. Inspections may occur annually or quarterly. The follow-up inspections verify that the fabricator is following the procedures outlined in the QA manual and none of the materials have been changed. In some cases, inspections may include random testing of parts to confirm that no changes have occurred since the initial testing. Once the listing is completed and the inspection schedule is set up, a label can be placed on any parts that are made under this listing. The label for all products sold under this listing will be designed and agreed on by the listing agency and the fabricator. The label assures code officials and architects that these parts meet the code requirements. They can look up the listing on the testing agency’s website to find details about the product. While it can be a laborious process, listing and labeling is beneficial to fabricators. Once listed, you don’t have to supply test reports on your product to code officials or architects. You can simply tell them where to look up the listing of the product, which includes all of the test reports. It should help facilitate sales in the construction market, and that’s something we all like to see!
