1.2 Warning - Mercury is a definite health hazard in use and disposal (See 12.1.)

For copper alloys in which zinic is specified as the remainder. either copper or zinc may be taken as the difference

between the sum of all the elements analyzed and 100%



TABLE 1 CHEMICAL REQUIREMENTS

^A Copper (including silver),
^B When the product is for subsequent welding applications, and so specified by the purchaser, zinc shall be 0.50% max,
lead 0.02% max, phosphorus 0.02% max, sulfur 0.02% max, and carbon 0.05% max.
When all the elements in Table 1 are analyzed, their sum shall be as shown in the following table.

TABLE 2 TENSILE REQUIREMENTS

TABLE 3 EXPANSION REQUIREMENTS

TABLE 4 NOTCH DEPTH

TABLE 5 DIAMETER OF DRILLED HOLES

Hydrostatic Test - Each tube shall stand, without showing evidence of leakage, an internal hydrostatic pressure
sufficient to subject the material to a fiber stress of 7000 psi, determined by the following equation for thin hollow
cylinders under tension. The tube need not be tested at a hudrostatic pressure of over 1000psi unless so specified.

P = 2St/(D-0.8t) where:
P = hydrostatic pressure, psig.
t = thickness of tube wall, in.
D = outside diameter of the tube. in., and
S = allowable stress of the material, psi.


TABLE 6 DIAMETER TOLERANCES

^{A Tolerances in this column are applicable to light drawn and drawn tempers only.
Tolerances for annealed tempers shall be as agreed upon between the manufacturer and the purchaser.}



TABLE 7 WALL THICKNESS TOLERANCES, PLUS AND MINUS IN.

TABLE 8 LENGTH TOLERANCES

^A Condenser tubes in lengths over 100 ft are not in present demand. Tolerance values for the lengths will be developed
as experience dictates. Tolerance values for lengths in wall thicknesses of 0.020, incl. to 0.032 shall be as agreed upon
between the manufacturer or supplier and the purchaser.

The properties and chemical compositions enumerated in this specification shall, in case of disagreement,
be determined in accordance with the following ASTM methods:

^A Reference to Specification B170 is to the suggested chemical methods in the annex thereof.
When E-1 Committee has tested and published methods for assaying the low-level impurties in copper.
the Specification B 170 annex will be eliminated.
