The Programme of Work is prepared by each Technical Department of The Bureau of Indian Standards to indicate the latest position of published Indian Standards, number of amendments issued on a particular published standard, month and year of their last re-affirmation, standards identified for revision or standards in the process of revision etc. It also indicates the draft documents at different stages of processing.
In the Programme of Work the "Equivalence" column indicates the Degree of Equivalence of an Indian Standard with existing International Standard.
The term "IDT" implies that the corresponding standard is "Identical" to an existing Interntional Standard either in Dual Numbering or Single Numbering.
The term "MOD" indicates that the corresponding Indian Standard is a Technically Equivalent/Modified form of an International Standard. "NEQ" indicates that the corresponding Indian Standard is Not Equivalent to the existing International Standard indicated. Blank Equivalence indicates that the Indian Standard is indigenously developed. The column "Reaffirmation Year and Month" indicates data corresponding to the last reaffirmation of the Standard.
