ISTA 3A Package Testing: Parcel Delivery System Shipments Less Than 150 lbs
ISTA 3A package testing evaluates the performance of a packaged-product related to vibrations, shocks and other stresses encountered during handling and transportation. As an ISTA and ISO 17025 certified lab, we realize the importance of ISTA 3A transit testing. Meeting the ISTA 3A integrity requirements can be difficult. We understand the challenges and guide companies through the process.
Keystone Compliance partners with customers to achieve package compliance. We provide comprehensive reports shortly after completion of the testing. Keystone provides the peace of mind that all of your needs will be met. Lastly, we create an accurate test plan to eliminate expensive over-testing.

Summary of ISTA 3A Integrity Testing
ISTA 3A package testing is a general simulation test for individual packaged-products shipped through a parcel delivery system. The ISTA 3A test procedure is appropriate for four different types of packages commonly distributed as individual packages, either by air or ground.
The ISTA 3 package test methods are standard, small, flat and elongated packages. ISTA 3A includes an optional test combining Random Vibration under Low Pressure (simulated high altitude). This tests the container’s (whether primary package or transport package) ability to hold a seal of closure and the retention of contents (liquid, powder or gas) without leaking.
Scope of ISTA Series 3A Laboratory Testing
ISTA 3A requires one test sample be tested unless the product is considered to be fragile or liquid. A fragile product is defined as an item that could easily break when dropped without having protective packaging.
ISTA 3A test drop heights may vary per package. Examples of fragile products include ceramics, clay, electronics glass and porcelains. Liquids include liquids as well as semi-liquids and solids that can become liquids if they are exposed to temperatures in excess of 70 degrees Fahrenheit.
STANDARD packaged-products are defined as:
- Any packaged-product that does not meet any of the definitions below for a small, flat or elongated packaged-product.
- A standard packaged-product may be packages such as traditional fiberboard cartons, as well as plastic, wooden or cylindrical containers.
SMALL packaged-products are defined as any packaged-product where the:
- Volume is less than 13,000 cm3 (800 in3) and
- Longest dimension is 350mm (14in) or less and
- Weight is 4.5kg (10lb) or less.
FLAT packaged-products are defined as any packaged-product where the:
- Shortest dimension is 200mm (8in) or less and
- Next longest dimension is four (4) or more times larger than the shortest dimension, and
- Volume is 13,000 cm3 (800in3) or greater
ELONGATED packaged-products are defined as any packaged-product where the:
- Longest dimension is 900mm (36in) or greater and
- Both of the packages’ other dimensions are each 2 percent or less of that of the longest dimension.
