decimal places required for angles
 

decimal places required for angles
using y14.5 and decimal inch on drawing, how should an angle of say 25.000 (basic) degrees be expressed. how many decimal places are required?
the standard seems to be a little vague or again i am overlooking.

2.3.3 angle tolerances. where angle dimensions
are used, both the plus and minus values and
the angle have the same number of decimal places.
example:
25.0° ±.2° not 25° ±.2°
when used in conjunction with positional tolerance, does the positional tolerance have any influence on the number of decimal places?
supposing 6 holes at 60 degrees, with a positional tol of .005 dia. is the angle required to have 3 trailing zeroes? again by the standard?
from a recent thread
while a positional tolerance does determine the number of decimal places in inch dimensioning, i have found no references to it affecting angular dimensions. i have always used only as many decimal places as required to define the requirements, be it none or three.

take a look at 2.3.2 (d) on pg. 25
as far as i know the number of trailing digits dictate the measuring equipment. for example: a dimension such as 10+/-0.1 need to be measured with a caliper having 0.01 accuracy. a dimension such as 10+/-0.10 has to be measured by a caliper or micrometer having 0.001 accuracy.
