English to Spanish Science Chemistry; Chem Sci/Eng Laboratory work

Hi, I would appreciate your help with a few terms.

I am translating documentation regarding Operative instructions and procedures with samples in a laboratory.

This specific document a bath control tests performed on metals.


Context for this term is (sorry about the caps and the awful writing in the text):
" 4.0- SPECIMEN IN METALLOGRAPHIC EXAMINATION
AFTER THE SPECIMEN WAS PREPARED ACCORDING TO CONDITIONS OF ITEMS 2.0 AND 3.0, IT SHALL BE CUTTED AND PRI_PREPARED FOR METALLOGRAPH1C ANALYSIS AT 100X OR HIGHER. IN ORDER TO OBSERVE END GRAIN PITTING AND INTERGRANULAR ATTACK AT GRAIN ENDS AND GRAIN BOUNDARY, RESPECTIVELY, SCAN THE ENTIRE SURFACE OF FACE "X” AND DETERMINE THE AREA WITH THE DEEPEST PITS AND MEASURE THEM."

thanks :)
