Notes:
- No pass/fail requirement - results are reported
- Load and span adjusted from actual calculated load of 92 psf at 24 inch test span. The span was multiplied by the adjustment factor of 92/100 to assume that the reduction of span by that factor will sustain a load of 100psf.
- Environmental effects are used to calculate adjustment factors for end-use. There are no pass/fail requirements since the results are factored in to the performance rating of the product.
