12.1.0 Definition Of Scrap :
Scrap can be defined as the material, which is no longer useful to the Railways for the purpose for which it was originally purchased or obtained. Scrap also consist of arisings of waste material from manufacturing and repairing processes such as turnings and borings, sweepings, foundry dross, off cuts of metals, waste paper, weeded out records, used tickets, wooden pieces and saw dust etc.
12.1.1 Types of Scrap : Scrap is a class by itself, and should be distinguished from surplus stores, and can be divided in two categories viz. :
(a) Ordinary scrap : These are the items, which have regular demands as raw material in the Railway Workshops such as cast iron, non-ferrous materials which are used for manufacturing various components of Rolling stock.
(b) Surplus Scrap : These are items which are not required by the Railways for their own use and are invariably disposed off by auction sale or other means. Even new or second hand material that is usable, may come in this category of scrap, if it is useless for the Railways. All surplus scrap is almost always `dead surplus".
