ISTA, Your Alliance in Transport Packaging, is the world leader in Performance Tests for Packaged-Products.

ISTA 3 Series tests are advanced tests and are designed to:

Challenge the capability of the package and product to withstand transport hazards, but Utilize general simulation of actual transport hazards, and

Do not necessarily comply with carrier packaging regulations.

When properly executed, ISTA procedures will provide tangible benefits of:

Product to market time reduction

Confidence in product launch

Reduction in damages and product loss

Balanced distribution costs

Customer satisfaction contributing to increased market share

There are three sections to this Procedure: Overview, Testing and Reporting

Overview provides general knowledge required before testing and

Testing presents the specific instructions to do laboratory testing and

Reporting indicates what data shall be recorded to submit a test report to ISTA.

Two systems of weights and measures are presented in ISTA test procedures: SI (Metric) or English system (Inch-Pound).

Metric units are shown first followed by the Inch-Pound units in parentheses; there are exceptions in some tables (when

shown separately).

Familiarity with the following units and symbols used in this document is required:

For measuring Metric units and symbols English units and symbols

Weight kilograms (kg) or grams (gm) pounds (lb)

Distance meters (m) or millimeters (mm) feet (ft) or inches (in)

Volume Cubic centimeters (cm3) Cubic inches (in3)

Density kilograms per cubic meter (kg/m3) pounds per cubic inch (lb/in3)

Temperature Centigrade (°C) Fahrenheit (°F)

Absolute Pressure Kilopascal (kPa) Pounds per square inch (psi)

Either system may be used as the unit of measure (standard units), but

The standard units chosen shall be used consistently throughout the procedure.

Units are converted to two significant figures and

Not exact equivalents.

NOTE:

In other ISTA Test Procedures 68 kilograms is used as the conversion from 150 pounds. In 3A, 70 kilograms and 150

pounds are used because it’s a common dividing point found in parcel delivery systems from countries that use either metric

(SI) or English (inch-pounds) units of measure.

VERY IMPORTANT:

The entire document shall be read and understood before proceeding with a test.

ISTA 3A 2006 - Page 2 of 25

OVERVIEW OF PROCEDURE 3A

Test Procedure 3A is a general simulation test for individual packaged-products shipped through a parcel delivery system.

The test is appropriate for four different types of packages commonly distributed as individual packages, either by air or

ground. The types include standard, small, flat and elongated packages. 3A includes an optional combination of a Vibration

and Vacuum (high altitude’s lowered air pressure) test. This tests the container’s (whether primary package or transport

package) ability to hold a seal or closure and the retention of contents (liquid, powder or gas) without leaking.

STANDARD packaged-products shall be 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 shall be defined as any packaged-product where the:

volume is less than 13,000 cm3 (800 in3), and

longest dimension is 350 mm (14 in) or less and

weight is 4.5 kg (10 lb) or less.

FLAT packaged-products shall be defined as any packaged-product where the:

shortest dimension is 200 mm (8 in) or less and

next longest dimension is four (4) or more times larger than the shortest dimension, and

volume is 13,000 cm3 (800 in3) or greater.

ELONGATED packaged-products shall be defined as any packaged-product where the:

longest dimension is 900 mm (36 in) or greater and

both of the package’s other dimensions are each 20 percent or less of that of the longest dimension. NOTE:

If a packaged-product is both Flat and Elongated, the package should be tested as Elongated

Testing can be used to evaluate the protective performance of a packaged-product related to vibrations, shocks and

other stresses normally encountered during handling and transportation in a parcel delivery system.

ISTA-3A包装测试标准.doc

Test levels are based on general data and may not represent any specific distribution system. The package and product are considered together and not separately.

Some conditions of transit, such as moisture, pressure or unusual handling may not be covered. Other ISTA Procedures may be appropriate for different conditions or to meet different objectives. Refer to Guidelines for Selecting and Using ISTA Procedures and Projects for additional information. NOTE:

Hazardous material packaging that passes this test procedure may not meet international, national or other regulatory

requirements for the transport of hazardous materials. This test in not a substitute for United Nations and/or any other

required test standards for the transport of hazardous materials, but should be used as an additional test in conjunction with

them.

Test Procedure 3A covers testing of individual packaged-products weighing 70 kilograms (150 pounds) or less when

prepared for shipment via a parcel delivery carrier.

The shipper shall determine the following prior to testing:

what constitutes damage to the product and

what damage tolerance level is allowable, if any, and

the correct methodology to determine product condition at the conclusion of the test and

the acceptable package condition at the conclusion of the test.

For additional information on this determination process refer to Guidelines for Selecting and Using ISTA Procedures and

Projects.

OVERVIEW OF PROCEDURE 3A

Samples should be an untested actual package and product, but if one or both are not available, the substitutes shall be as

identical as possible to actual items.

One sample is required for this test procedure.

To permit an adequate determination of representative performance of the packaged-product, ISTA: Requires the procedure to be performed one time, but

Recommends performing the procedure five or more times using new samples with each test.

Refer to Guidelines for Selecting and Using ISTA Procedures and Projects for additional information on statistical sampling.

NOTE:

In order to ensure testing in perfect condition, products and packages shipped to an ISTA laboratory for

ISTA-3A包装测试标准.doc

testing shall be:

Adequately over-packaged for shipment or

Repackaged in new packaging at the laboratory.

NOTE:

It is important to thoroughly document the configuration, materials, and construction of the tested product and package.

Significant variations in performance can sometimes be caused by seemingly insignificant differences. Photo

documentation is strongly recommended to supplement detailed written descriptions.

Basis Weights of Corrugated Board

When the outer package is a corrugated box, it is strongly recommended that the basis weights of the papers/paperboards

used to make the box be determined and documented. It has been determined that basis weights are better indicators of

box equivalence than ECT or Burst ratings.

Refer to Guidelines for Selecting and Using ISTA Procedures and Projects for additional information on documentation and

basis weight determination.
