Y14.5-82 vs. Y14.5-94

Y14.5-82 vs. Y14.5-94

Our company has continued to use the 1982 standard to the present.  The question now has arisen if it would be prudent to "update" to the 1994 version. Does anyone know a concise source of comparison between the two versions?

Many thanks.

Appendix A of the 1994 spec has a description of the changes.

Agreed, the appendix is a good place to start, and to really use it one must go through it and pull from each version the sections that it discusses and see how the change came about. The difficulty to be overcome is that there is not always a one-to-one correspondence. However, difficulty is what makes the learning memorable.

The foreward also provides insight. Not exciting, but useful.

'94 clarifies a few things and adds at least as many new gaps as filled.

How beneficial it is depends on how much the previous standard was used and how properly.
