Test reports
Actual test data (i.e. temperature data, required observations, other measurements, etc.) is available within NFPA 285 test reports. These reports often include proprietary information that may disclose proprietary research, product, or other confidential business information that is not appropriate for the public domain. Test reports are provided to the test sponsor (the entity that initiates and funds the laboratory to perform the testing) and to any other party authorized by the test sponsor (e.g. a co-sponsor). Test sponsors are typically building product manufacturers; however, any party may engage with a testing laboratory to perform a test.
The typical use of NFPA 285 tests is to collect performance data for subsequent analysis. When combined with the almost infinite number of possible exterior wall configurations, it is unlikely one will be able to find a test report for the exact assembly (or assemblies) used on a given project. It is for this reason engineering analysis and extensions are often needed. Also, as previously noted, the amount of data and sensitivity of the contents make the distribution of test reports inappropriate.
Manufacturer information
Although manufacturers do not customarily provide the actual test reports, most will provide NFPA 285 compliance information on their websites. Manufacturers often publish various types of documents (e.g. Tech Sheets, Guides, etc.) that describe assembly details, options, and limitations based on tested assemblies containing their products. A simple internet search containing “product name or manufacturer name” and “NFPA 285” will typically lead one to this information. If one is unable to find the necessary information, has questions about it, or needs to know if a specific assembly complies, they should contact the customer service or technical assistance department.
There are several things to consider when searching manufacturers’ websites or contacting them to collect information regarding NFPA
285 compliance:
- It will be necessary to contact the manufacturer directly to make requests regarding engineering extensions of tested assemblies to address a specific project need.
- Manufacturers tend to have the most specific and necessary information about important assembly details such as window head, jamb,
and sill details and extensions of test results. - It is possible that a given manufacturer may not have all available information regarding NFPA 285 compliant assemblies containing their product (e.g. a foam plastic insulation manufacturer may not have awareness of, or access to, testing with their foam that was performed by a cladding manufacturer).
