Parcel Delivery System Shipments 150 lb (70kg) or Less

The ISTA 3A testing procedure is a general
simulation test for individual product packages sent via a package delivery
service such as UPS
, DHL, FedEx, etc., whether by air or land. ISTA specifies that the 3A testing procedure
covers the testing of individually packaged products weighing up to
and including 70 kilograms (150 pounds) when prepared for shipping via a package
transport company.

More specifically, the test is designed to test four
different types of packages that are usually distributed as individual
packages. These types of packages include standard, small, flat and
elongated packages.

For example, a standard
packaged product might be a traditional cardboard box, plastic containers such
as paint buckets, or wooden box for the transportation of more fragile

In the case of small packages, they must have the following

The volume is under 13,000 cm³
(800 in³), and

The longest dimension is 350 mm
(14 inches) long or less and

Its weight is 4.5 kg (10 lb) or

One example of a small package
would be a small cardboard box that can transport products with a weight up to
and including 4.5kg.

Conversely, flat packaged products should meet the following

The shortest dimension is 20 mm
(8 inches) or less and

The next, longest dimension is
four or more times longer than the shortest dimension, and

Its volume is 13,000 cm³ (300 in³)
or greater.

A good example of this type of
package would be the box that protects a laptop.

In addition, ISTA 3A includes an optional test
that combines random vibrations at low pressure, simulating a high
altitude, as if the package were transported by air. This tests the ability of
a container (whether the primary package or transportation package) to remain
sealed or closed and contain its contents (liquid, powder or gas) without
