DRAFT OF REODLATIONs REFERRED TO IN THE AWNS
NoTICE As TO THE TESTING oF CAST STEEL ANCHons.
1. The regulations as to the marking and certifying
of cast steel anchors shall be the same as are now in
ferce for wrought iron anchors, but, in addition, the
words "cast etsel " must be stamped on each anchor, or
on each cast steel portion of the anchor when it is made
of more than one cisting ; and for the present the ex-
emination of and proof strain to be applied to, such
suchors shall be the same as are now in force for
wrought iron anchors of equal weight, but the statutory
precf strain must not be applied to any cast steel anchor
until the material of which it is made has been tested for
it mile strength an' ductiaty and found satisfactory.
'2. The tests for tensile strength and ductility must
be made at a public Proving Establishment, where it
is intended to apply the proof strain.
3, There must be three pieces cast on each anchor,
or on each piece of tie anchor when it is made of more
than one casting, two of which must be tested for tensile
strength, contraction of area, and elongation, and the
other must be beet while cold. These test pieces must
be fairly diets Bitted over each casting.
4 No cast steel anchor, or portions of a cast steel
anchor, should be received at a Proving Establishment
with all or any of the tact pieces broken or cut off.
5. When a Soperintendeut of a Proving Establish-
ment receives a cast steel anchor for testing purposes he
should at once have the test pieces cut off, then have
them prepared and tested, and, if the resn.ts are satis-
factory, he should, if the anchor seems sound, apply the
proof strain-
-6 Ihe piling pieces must be turned in the lathe to
lin, diameter for a length of 10in , and the elongation
taken in that leagth.
The bending pieces must be machined to lin, square
for 3 length of 3 2in • and bent by screw or LI diaulic
p•esi sure on supports 10in, apart until they pass between
,Le supports ; they are then, if uncra ked, to be bent by
pressing the ends together until they break, or until
ttier sides are parallel at a distance of 3m, apart,
!net snred inside.
1 he et dof the hydraulic ram, or part that presses on
the test pieces, saculd ba semi.cyluadrical, the radius
b-it g ho., and its depth shou:d bs it least 2in,
7. '1 he tensile strength of the test pieces seonld not
xceed l:;0 tons per square inch of section.
The cent' action of area of the test pieces at the
fracture should not be le e than 4 per cent
ILe elongation cf the test pieces in a length of 10in.
hou d not Le less than IS per cent.
he bending test pieces shculd bear bending until the
sid, s are parallel at a distance apart of 3iu., me:retired
iie aithunt flow or fracture.
8 If the tensile strength exceeds 30 tons per square
ineb Of section, the results of the tests are to be re-
garded as unsatisfactory, and unless two out of the three
teats for ducti ity. viz , contraction of area, elongation,
and bending, be in accerdancs with the requirements
seat. d herein, th: results of the tests are also to be re-
garded tts UnstiLsfactory.
9. Material which contains blow-holes caanot be
lOgarded as suitable, aud the proof 'strain shoute not be
epptied in such cases; and when blow-holes are 4 bserved
"i a tested suebor it ahould not be certified to.
•0. Ihe eseehor shackle sue its Lott, tog, titer with
such parts as forelocks, must be made of wrought iron.
