 A
successful gage calibration system can be effective only if you can readily
and easily identify gages and when they need calibration. The key to proper
gage identification is a reliable labeling system. Beyond the information
included on the label, there are several other factors that determine
whether your gages are properly labeled and how the label information
integrates with your tracking system. Here are some questions to ask when
setting up a labeling system:
- Should our labeling material be paper, laminate, or polyester? Do
the labels have to be laminated or coated in some way to protect the
information from chemicals, water, or grease? Evaluate the environment
in which your gages are used to help you determine which type of label
you need.
- Should the labels be permanently affixed or do they have to be removable?
If they have to be removable, will the adhesive attach them well
enough to prevent labels from constantly failing off and having to
be reattached?
Labels that don’t attach properly will eventually end up on the
floor or the sole of someone’s shoe.
- Can we buy off-the-shelf labels or do we require custom-printed labels?
The answer to this question may be dictated by factors beyond your control,
such as ISO/QS 9000, ISO 14000, FDA, or ANSI-Z540 requirements; internal
company specifications; or outside calibration-house needs.
- What information must be included on each label? Is the same information
required for all gages in all departments or does the amount of required
information change? Will one standard label work or are several different
labels required? Will label color play a role in the calibration system?
- How will information be printed on the label? Can it be handwritten?
Is it better to print labels on a computer printer? Will our calibration
software print labels for us? Does the ink have to be permanent and
waterproof? Test any ink prior to use. Many "permanent and waterproof"
inks aren’t permanent and/or waterproof on all surfaces.
Many of today’s calibration software programs feature
the ability to print labels directly from the software database. Programs
such as CyberMetrics’ GAGEtrak calibration software will work directly
with a label printer. The main advantages of a direct connection between
the calibration database and a label printer is the greatly reduced opportunity
for data-entry errors, excellent readability of labels and time savings.
 Though a calibration label
seems like such a simple thing, it can be an ongoing frustration. Some
advanced planning and analysis of your labeling needs will help you properly
establish this cornerstone of your gage-calibration system.
