Design Criteria and Allowable Variances
In order to remain within the design criteria the assembly must be constructed as specified in the published design. There are three potential types of acceptable modifications, as follows:
- If a construction element is identified as "optional" or "may be provided" it is not mandatory and doesn't need to be included in the construction.
- If a dimension is indicated as a minimum or maximum, the construction can include greater or lesser dimensions, respectfully.
- The link at the top of each design entitled "See General Information for Fire-resistance Ratings - UL 263" should be consulted. This link provides information on construction details, including clarifications and permitted variations.
