it meets the Product Damage Tolerance and Package Degradation
Allowance.
ISTA Certified Testing Laboratories:

The ISTA Transit Tested Certification Mark as shown is a:
• registered certification mark and
• can only be used by license agreement and
• by a member of the International Safe Transit Association.
When a member prints this certification mark on a packaged-product with
their license number they are showing their customer and the carrier that it

In order to maintain its certified status and eligibility for identification with the
TRANSIT TESTED Certification Mark, each packaged-product must be
re-tested whenever a change is made in the:
• Product or
• Process or
• Package.
Changes in the product include changes in:
• Design or
• Size or
• Materials.
Changes in the process include changes in:
• Manufacturing or
• Assembly or
• Filling.
Changes in the package include changes in:
• Configuration or
• Dimensions or
• Weight or
• Materials or
• Components.
As a quality control procedure, packaged-products should be re-tested
frequently, for example, yearly.

• Number of vibratory impacts, and
• Results of visual inspection for damage, if applicable

Report the following:
• Orientation of each shock
• Severity of each shock recorded:

- For free fall equivalent as velocity change in inches per second
(m/s)
- For incline as impact velocity in inches per second (m/s)
- Horizontal equivalent as velocity change in inches per second
(m/s)
Report if an incline or horizontal shock was substituted for any test
