Examination characteristics with applicable packing in templates.
1. Smallest permissible stack height indicated when surfaces X and Z of low tolerance
templates come together and angle surfaces of both templates and packing ring are in contact
within allowable angularity limits of AN6225.
2. When angle surfaces of both template and packing ring are in contact, but surfaces X
and Z are apart, revert to high limit tolerance template.
3. Highest permissible stack height indicated when surfaces X and Z of high tolerance
templates come together and angle surfaces of both templates and packing ring are in contact
within allowable angularity limits of AN6225.
NOTE: Care should be taken to not injure sealing lips of packing with templates.
Dimensions in inches. Template tolerances, unless otherwise specified, ±.001, angles ±1/2°.
