Sec. 23.10  Misuse of ``corrosion proof,'' ``noncorrosive,'' 
``corrosion resistant,'' ``rust proof,'' ``rust resistant,'' etc.

    (a) It is unfair or deceptive to:
    (1) Use the terms ``corrosion proof,'' ``noncorrosive,'' ``rust 
proof,'' or any other term of similar meaning to describe an industry 
product unless all parts of the product will be immune from rust and 
other forms of corrosion during the life expectancy of the product; or
    (2) Use the terms ``corrosion resistant,'' ``rust resistant,'' or 
any other term of similar meaning to describe an industry product unless 
all parts of the product are of such composition as to not be subject to 
material damage by corrosion or rust during the major portion of the 
life expectancy of the product under normal conditions of use.
    (b) Among the metals that may be considered as corrosion (and rust) 
resistant are: Pure nickel; Gold alloys of not less than 10 Kt. 
fineness; and Austenitic stainless steels.
