GENERAL MECHANICAL SPECIFICATION FOR ROTATING EQUIPMENT AND PACKAGES

Impact Testing
Impact test specimens shall be Type A, Charpy V-notch, conforming to ASME PV code, Section VIII, Division1, sub-section UG84 — “Charpy Impact Test”.
For full size specimens, each impact test shall consist of testing a set of 3 impact specimens from a single test coupon or test location and having the same orientation.

В последнем предложении затрудняют 2 момента: как разделить impact specimens и test coupon, чтобы не повторять слова "образец", и к чему относится фраза "having the same orientation".

Спасибо.
