This table is used by air samples and contains time weighting factors for various limit types. You can define whether a sample type is time weighted, and what the time weighting period should be (in minutes). For example, a TWA8 sample would be time weighted and the weighting period would be set to 480 minutes. A STEL could be done in the same way and configured as 15 or 30 minutes.
