typical or typ notation on drawings
anyone know the exact definition for the notation: typical or typ? i have some old drawing that use them. i'm not sure where or when to use them, or if it is even a standard. any info is appreciated.

not standard, but are typically used.
i have seen ".25 dia holes, typ". what does that mean?
i don't use it.

as far as a textbook definition goes, i probablly could not give it to you, but the use of typ is pretty simple. if something is typical, say so...
1. in lieu of counting and giving the discrete number of instances.
for example if you have a sheet metal part where all the break radi is .5 in, you would leader one radius and annotate ".50 typ".
or
2. if you have a detail that occurs in 6 places on the drawing, you can add to the detail title "typ 6 pl" meaning that all six places are the same.
bacically you are saying all the things that look like "this" mean "this"

typical or typ indicates the number of places the geometry feature or dimension appears on a drawing it could be in ansi/asme y1.1-1989 abbreviations for use on drawings and in text.

never argue with an idiot. they'll bring you down to their level and beat you with experience every time.
according to the latest standard, typ is no longer used.

sadly mad mango is correct.  i got this pointed out to me by my checker a while back.
i used to use it a lot back in the uk, especially on things like chamfers and rads.
thanks mm.
i knew it wasn't standard, but wasn't sure where exactly in the spec. it was ok in 1982 std.

thanks guys for the quick reply and info. mm thanks for pointing it out that it is no longer a standard. i will do a lil more digging to see it this applies to us anymore.
if your company is typ, it will.

actually, the 1982 spec says the same as the 1994 one.
