the rails of the heat will be
accepted, provided they conform to the other requirements of these
specifications, as No. 1 or No. 2 classification (according as the
deflection is less or more, respectively, than the prescribed limit[F]).

"(D) If any test piece, test A, does not break, but when nicked and
tested to destruction shows interior defect, the top rails from each ingot
of that heat shall be rejected.
[Sidenote: Drop testing machine.]
"14. The drop-testing machine shall be the standard of the American
Railway Engineering and Maintenance of Way Association, and have a
tup of 2,000 lbs. weight, the striking face of which shall have a radius
of five (5) in.
"The anvil block shall be adequately supported and shall weigh 20,000
lbs.
"The supports shall be a part of or firmly secured to the anvil.
[Sidenote: No. 1 Rails.]
"15. No. 1 rails shall be free from injurious defects and flaws of all
kinds.
[Sidenote: No. 2 Rails.]
"16. Rails which, by reason of surface imperfections, are not accepted
as No. 1 rails, will be classed as No. 2 rails, but rails containing
physical defects which impair their strength, shall be rejected.
"No. 2 rails to the extent of five (5) per cent. of the whole order will be
received. All rails accepted as No. 2 rails shall have the ends painted
white, and shall have two prick punch marks on the side of the web
near the heat number near the end of the rail, so placed as not to be
covered by the splice bars.
"Rails improperly drilled, straightened, or from which the burrs have
not been properly removed, shall be rejected, but may be accepted after
being properly finished.
"Different classes of rails shall be kept separate in shipment.

"All rails shall be loaded in the presence of the inspector.
[Sidenote: Inspection.]
"17. (a) Inspectors representing the purchaser shall have free entry to
the works of the Manufacturer at all times while the contract is being
executed, and shall have all reasonable facilities afforded them by the
Manufacturer to satisfy them that the rails have been made in
accordance with the terms of the specifications.
"(b) For Bessemer Steel the Manufacturer shall, before the rails are
shipped, furnish the Inspector daily with carbon determinations for
each heat, and two complete chemical analyses every twenty-four hours
representing the average of the other elements specified in section 2
hereof contained in the steel, for each day and night turn respectively.
These analyses shall be made on drillings taken from the ladle test
ingot not less than 1/4 in. beneath the surface.
"For Open-Hearth Steel, the makers shall furnish the Inspectors with a
complete chemical analysis of the elements specified in section 2
hereof for each melt.
"(c) On request of the Inspector, the Manufacturer shall furnish
drillings from the test ingot for check analysis.
"(d) All tests and inspections shall be made at the place of manufacture,
prior to shipment, and shall be so conducted as not to unnecessarily
interfere with the operation of the mill."
