reproducing and preserving the original
record.
(b) Copies of records treated as original
records. Whenever records are repro-
duced under this section, the repro-
duced records will be preserved in con-
veniently accessible files, and provi-
sions will be made for examining, view-
ing, and using the reproduced records
the same as if they were the original
record, and they will be treated and
considered for all purposes as though
they were the original record. All pro-
visions of law and regulations applica-
ble to the original are applicable to the
reproduced record. As used in this sec-
tion, ‘‘original record’’ means the
record required by this part to be

Transfer a 25 ml ali- quot of the solution to a titration flask, add 10 ml of 1 percent barium chloride solution, 0.2 ml of 1 percent phenolphthalein indicator, and 50 ml of distilled water. Titrate with 0. N hydrochloric acid to the disappearance of the pink color. Not less than 25 ml of the hy- drochloric acid shall be required to neu- tralize the sample of diluted 50 percent caus- tic soda, and not less than 36.5 ml of the hy- drochloric acid shall be required to neu- tralize the sample of diluted 73 percent caus- tic soda. One ml of 0.25 N hydrochloric acid equals 0.01 gram of sodium hydroxide (anhydrous).
