Title: RE: Mill tests

Remember that all of the old specifications just listed a minimum strength.  Many mills are rolling significantly higher.  This is the reason for the new specification used in earthquake areas that lists a high and low strength.

In the case of handrails, this is moot because OSHA requires 1 1/2" nom. railings.

"29 CFR 1910.23(e)(3)(ii)
(e)(3)(ii)
For pipe railings, posts and top and intermediate railings shall be at least 1 1/2 inches nominal diameter with posts spaced not

more than 8 feet on centers.

(e)(3)(iii)
For structural steel railings, posts and top and intermediate rails shall be of 2-inch by 2-inch by 3/8-inch angles or other metal shapes of equivalent bending strength with posts spaced not more than 8 feet on centers.
