The manufacturer shall afford the inspector all dimensions more than 72 in. The minimum temperatures listed are for longitudinal tests. The manufacturer shall report the specimen which case the silicon content at the time of vacuum deoxi- orientation, test temperature, and absorbed energy for each dizing shall be 0.

NOTE 2 — Thickness shall be measured 10 to 20 mm from the longitudinal edge. Sharp corners on edges When tighter bends are required, the manufacturer should and on punched or gas cut holes should be removed by be consulted.

Determination shall as,e in accordance 9. NOTE 4 — The variations given in this table apply to plates that have a minimum specified tensile strength not over 60 ksi or comparable chemistry or hardness.

Strain Age Test variations from flatness given in Table 5 or Table 6. The number of plates tested and the specimen orientation shall test report shall indicate that the steel was vacuum carbon- be the same as in C The specification in 1. NOTE 3 — When the longer dimension is under mm, the variation shall not exceed 10 mm.

If the plate thickness It is, therefore, incumbent on designers three test temperatures defined for each grade. Charpy V-notch tests shall be conducted on the strain aged specimens. If only one organization is involved in the need not be done by the organization that did the hot hot rolling and processing operations, that organization is rolling of the plate.
