By Tanner Vandenberg, CEO, FlexPak Leak Detectors Inc.
ASTM packaging standards are the test methods, practices, guides and terminology that ASTM International publishes for packages and packaging materials. Most come from two ASTM committees: D10 on Packaging, which covers shipping and distribution, and F02 on Primary Barrier Packaging, which covers flexible and medical packaging. Together they give manufacturers, customers and auditors a shared way to specify and test a package.
We build leak detection equipment that runs several of these tests, so this guide groups the standards by what they prove, and says plainly which ones our equipment performs.
What is ASTM?
ASTM stands for the American Society for Testing and Materials. Founded in 1898, it now operates as ASTM International and publishes more than 13,000 voluntary consensus standards across many industries. “Voluntary” matters: an ASTM standard only becomes a requirement when a customer, a contract, a regulator or another standard points to it.
ASTM publishes several types of standard, and the type tells you how to use it:
- Test method: a defined procedure that produces a result, such as ASTM D3078 for leaks.
- Practice: a set of instructions for an activity, such as ASTM D4169 for distribution testing.
- Guide: options and advice rather than a single procedure, such as ASTM F2097 for medical packaging design.
- Specification: requirements a material or product must meet.
- Classification: a way of grouping materials or products by their characteristics.
- Terminology: agreed definitions, such as ASTM D996 for packaging.
ASTM requires each standard to be reviewed at least every five years, so check the edition year when a customer specifies a standard.
Packaging Standards
Purpose of Packaging Standards
A packaging standard lets two companies mean the same thing. When a customer asks for “ASTM D3078 at 20 inHg for 30 seconds,” both sides know exactly what test was run and what a pass means. Without that, every supplier would define “leak tested” differently. That is why ASTM methods sit behind so many packaging industry standards and packaging quality standards set by retailers and brand owners.
Importance of Packaging Standards
The practical value shows up in three places:
- Customer and retailer specifications. Large buyers often write ASTM methods into their supplier requirements.
- Audits. A named method with recorded settings is easier to defend than an in-house check.
- Regulated products. Medical packaging standards such as ISO 11607 list ASTM methods among the test methods manufacturers can validate and use.
Types of ASTM Packaging Standards
Here are the ASTM standards packaging teams run into most often, grouped by what they prove.

| Parcel shipping performance | ASTM D7386 | Practice | No |
| Closing, sealing and reinforcing fiberboard boxes | ASTM D1974 | Practice | Not applicable |
| Design and evaluation of flexible medical packaging | ASTM F2097 | Guide | Not applicable |
ASTM D996
ASTM D996 is the Standard Terminology of Packaging and Distribution Environments. It is a compilation of definitions of technical terms, grouped by application. It is not a test, but it is worth reading first: many disputes over test results turn out to be disagreements about what a word like “leak” or “shipping unit” means.
ASTM D3078
ASTM D3078 is the standard method for finding leaks in flexible packaging by bubble emission. The package goes under water in a clear vacuum chamber, vacuum is drawn, and a steady stream of bubbles shows exactly where the package is leaking. The standard recommends holding vacuum for about 30 seconds. It needs a package with headspace; vacuum-sealed packs need an attachment that adds air first. Its sensitivity is stated as a leak rate, not a hole size.
ASTM F2096
ASTM F2096 detects gross leaks by internal pressurization. The package is punctured, air is fed in at a set pressure while the package is under water, and a stream of bubbles marks the leak. It is a destructive test. The standard’s round-robin study found it detects a 250 µm (0.010 in) defect with about 81% probability, established on spunbonded polyolefin (Tyvek), which is why it is most common in medical and pharmaceutical packaging. Operators should exercise extreme caution when handling the needle at all times.
Key applications of ASTM F2096 include:
- Tyvek and other porous medical pouches
- Sterile barrier systems validated to ISO 11607
- Nonporous flexible packages where a destructive test is acceptable
ASTM D6653
ASTM D6653 tests how packages handle high altitude, such as in feeder aircraft or over mountain passes. It lowers the pressure in a vacuum chamber to simulate altitude and holds it. It conditions the package; it does not detect leaks by itself. To find out whether a seal opened, follow it with a leak test such as ASTM D3078.
Typical testing scenarios involve subjecting packages to:
- Reduced pressure equal to a set altitude, commonly 14,000 or 16,000 ft in the standard
- A hold at that pressure, then a controlled return to normal pressure
- Inspection for damage, deformation and leaks afterwards
ASTM D7386
ASTM D7386 is the Standard Practice for Performance Testing of Packages for Single Parcel Delivery Systems. It is written for shipping units up to 150 lb (68 kg) sent through small-parcel carriers. It puts the package through a sequence of the hazards it would meet in that system.
ASTM D7386 includes assessments such as:
- Drops and impacts
- Vibration
- Compression and other handling hazards
Benefits of Using ASTM Packaging Standards
Enhances Product Safety
A named test method gives you a repeatable check on the failures that make products unsafe: leaks that let in air, moisture or microorganisms, and seals that fail under stress. Because the method is defined, a result from one shift, plant or lab means the same as a result from another.
Improves Shipping and Handling Efficiency
Distribution practices such as ASTM D4169 and D7386 let you find weak packaging in the lab instead of in the field. They also give you data to argue for, or against, a packaging change.
Minimizes Product Damage and Loss
Leak and seal tests catch defects such as channel leaks, pinholes and seal-bar drift before product ships, which is far cheaper than a customer complaint or a withdrawal.
Is There Such a Thing as ASTM-Certified Packaging?
No. ASTM writes standards; it does not certify packages, equipment or companies. When a supplier offers “ASTM-compliant packaging solutions,” it should mean the packaging has been tested to a named ASTM method, with recorded settings and results. Ask for the standard number, the edition year, the test settings and the report. Equipment works the same way: our leak detectors are built to run tests to ASTM D3078, F2096, D5094, D4991 and D6653, but it is your test records that show compliance.
How to Choose the Right ASTM Standard
- Start with what the customer or regulator names. If a specification cites a standard, use that one and that edition.
- Match the method to the package. Headspace favors D3078. Porous medical pouches favor F2096. Liquid-filled closures favor D5094.
- Separate integrity from strength. A seal can be strong and still leak. See the difference between seal strength and seal integrity.
- Add distribution only if the risk is in shipping. Use D4169 or D7386 for handling, and D6653 for air freight.

Frequently Asked Questions
What is ASTM in packaging?
ASTM International publishes the standards packaging teams use to define and test packages, mainly through its D10 Packaging and F02 Primary Barrier Packaging committees.
How many ASTM standards are there?
ASTM International says more than 13,000 of its standards are in use worldwide. Only a small share relate to packaging.
Is ASTM a code or standard?
ASTM publishes standards, not codes. A standard becomes mandatory only when a law, regulation, contract or customer specification references it.
What are the ASTM classification standards?
A classification is one of the types of standard ASTM publishes. It groups materials, products or systems by shared characteristics. Most packaging work uses test methods and practices instead.
What is the ASTM standard for corrugated boxes?
There is not just one. ASTM D5118 covers fabricating fiberboard shipping boxes, and ASTM D1974 covers closing, sealing and reinforcing them. Box performance is usually tested within a distribution practice such as ASTM D4169.
Which ASTM packaging standards does FlexPak equipment run?
ASTM D3078 bubble emission, ASTM F2096 internal pressurization with the FPIPA add-on, ASTM D5094 and D4991 dry chamber tests, and ASTM D6653 altitude conditioning. We do not make seal strength (F88), dye penetration (F1929) or vacuum decay (F2338) equipment.
