A Including other non-corrosive liquids and gases.
B ASTM B 32, Alloy Grade Sn50.
C ASTM B 32, Alloy Grade Sb5.
D This pressure is determined by the temperature of saturated steam at 15 Ib. (6.8 kg) pressure at 250oF (121oC).
E This pressure is determined by the temperature of saturated steam at 120 Ib. (54.4 kg) pressure at 350oF (177oC).

 

   F 当工作温度低于121oC，可采用上述焊料。
G 1986年颁布的《美国安全饮用水法》规定，任何用于饮用水系统的焊料其铅含量不得超过0.2%.
H 额定内部压力是所连接的管道额定内部压力。如果可以采用焊料，则推荐使用铜焊合金。
F For service temperatures lower than 250oF (121oC), the solders as above may be used.
G The Safe Drinking Water Act Amendment of 1986 prohibits the use in potable water systems of any solder having a lead content in excess of 0.2%.
H Rated internal pressure is that of the tube being joined. While solders can be used, brazing alloys are recommended.
