SYSTEM 21
System 21 provides for interchangeable
assembly with respect to functional size only. Functional size must be measured
at the maximum material limit within the length of standard gaging elements.
The characteristic known as NO GO functional diameter must also be verified.
This can be accomplished by using fixed limit gaging or variable gaging with
functional elements.
SYSTEM 21A (FOR METRIC THREADS IN
ACCORDANCE WITH ANSI B1.18M)
System 21A provides for interchangeable
assembly with functional size verified at the maximum material limit using
standard length gaging elements. This can be accomplished using fixed limit
gaging or variable gaging with functional elements. System 21A also states that
the minimum material limit (minimum pitch diameter) must be verified by
inspecting two thread flank locations over the length of the thread. This can
be accomplished by using variable gaging or thread roll snap gages with pitch
diameter elements.
SYSTEM 22
System 22 provides for the interchangeable
assembly with functional size verified at the maximum material limit using
standard length gaging elements. This can be accomplished using fixed limit
gaging or variable gaging with functional diameter elements. System 22 also
states that the minimum material limit (minimum pitch diameter) must be
verified over the full length of the thread. This can be accomplished using
variable gaging with pitch diameter elements.
SYSTEM 23
System 23 provides for interchangeable assembly
with functional size verified at the maximum material limit using standard
length gaging elements and minimum material limit (minimum pitch diameter) must
be verified over the full length of the thread. The gaging requirements for
SYSTEM 22 would also apply here but in SYSTEM 23 other thread characteristics
such as lead, flank angles, taper and roundness must have to be independently
verified. Only thread characteristics, which are specified, will have to be
inspected for SYSTEM 23 compliance.
TC & ITC Comparators
Precision
Ball slide construction and constant gaging
pressure assure precise reading through linear travel of the ball slide.
Definitive
Helical path seating and 60% peripheral
contact provide functional size position within the pitch diameter tolerance
assigned.
Gaging Range
Single frame covers a size range of #10
through 3/4".
Versatile
Segments are easily changed with positive
mounting pin alignment.
Economical
Reduced gaging time compared to Go/NoGo
gages .
ITC Comparator
Precision
Rigid construction and constant gaging
pressure assure precise readings.
Definitive
The ITC gage reads the actual size of the
pitch diameter showing its position in relation to the pitch diameter tolerance
assigned.
Gaging Range
Single frame covers a size range of #10
through 2 1/2" , Larger frames are available up to 8"
Versatile
The positive alignment feature of the frame
allows segments to be easily changed with positive mounting pin alignment.
Economical
Reduced gaging time compared to Go/NoGo gages.
