Question

Which of the following is not a function of a Colour Pattern?

(a) To show the location of the parting surface

(b) To identify the parts of the castings

(c) Indicate the type of metal to be cast

(d) Identify the core prints

I had been asked this question by my school teacher while I was bunking the class.

I need to ask this question from BIS Colour Coding in division Casting Processes of Foundry and Forging

Answer 1

Right answer is (a) To show the location of the parting surface

For explanation I would say: The Colour Pattern given by the American System of Colour Code for Castings is to show the location of the pattern construction. The location of the parting surface is depicted by the separating part of the cope and drag or the flat surface in case of single piece pattern.
