Resolution
Warning!!
The following statement is only a resolution to a Standard Improvement Request (SIR) and is NOT part of the current DMIS standard, nor is it guaranteed to become part of the next revision of the DMIS standard even if voted and accepted by the DMIS National Standards Committee. This resolution is tentative because it may not be incorporated into the next version of the standard, it could be changed prior to the next release, or it could be changed as the result of the "public review and comment" period required for the next version of the standard. If you choose to use this tentative resolution, you do so at your own risk since at this time it is not part of the DMIS standard.
Resolution: Modify the VALUE statement to gain access to the tolerance value when more than one value is possible (e.g, COMPOS, CPROFS). The modification will be to extend a TA's var_1 with a var_3.
Where:
| var_1 can be: | FA(label),SIZE |
| or: | TA(label),var_2 var_3 |
| var_2 can be: | INTOL |
| or: | OUTOL |
| or: | ACT |
| or: | DEV |
| or: | AMT |
| var_3 can be: | ,n |
| or: | does not exist |
Add a 'n' definition:
"n is the n'th specified value of the tolerance. If not specified, the first value will be used."
Add note:
"Note: The 'n' is typically used to gain access to either the first or second tolerance value for a composite tolerance (e.g., COMPOS, CPROFS). If 'n' is not specified, the value returned is the first tolerance value."
