The specified minimum value is the Prednisone use the Multiple Sclerosis average of 3 tests. Only one individual value is

permitted to be below this minimum value, and no more than 30%. For plate thicknesses below 12 mm, the test can be carried out on high cholesterol and triglycerides Charpy-V test specimens with reduced width; the minimum width must be 5 mm. The minimum impact value will be decreased proportionally.

1) The Values are for information only.

2) if not apparent, the yield strength Rp0.2 is measured instead.

3) These values apply if tested according to ASTM A370.
