The ASTM D6653 standard governs testing of packaging resistance to reduced atmospheric pressure, a stress typically encountered during air transport and high-altitude logistics. Here is what it actually covers, how a test is carried out, and how ACRN can help you test your packaging.

What is the ASTM D6653 standard?
Published by ASTM International, this standard defines a test method for evaluating the effects of high altitude on a complete packaging system: the product, primary packaging, secondary packaging and closures, tested together exactly as they would be shipped. The test applies to any container shape: bottles, cans, cartons, flexible pouches or vacuum-packed items.
In practice, the test simulates the pressure drop encountered in an aircraft cargo hold or at high altitude by depressurizing the specimen inside a vacuum chamber. The goal is to verify that the packaging protects its contents without seal rupture, container deformation or product leakage, even when outside pressure drops sharply. The full standard is available from ASTM International.
Why does this standard matter?
- Fewer losses: anticipating how packaging behaves at altitude before shipping helps avoid product returns and carrier disputes.
- Stronger credibility: complying with an international standard demonstrates that your company is committed to quality and safety.
- Cost optimization: avoiding returns or claims linked to packaging failures directly improves your logistics profitability.
- Regulatory and contractual compliance: many customers in food, pharmaceutical and electronics industries require proof of compliance before approving packaging.
How does the test work?
The standard describes two distinct procedures, chosen according to the flight or transport profile to be simulated.
Procedure A and procedure B
Procedure A applies a rapid decompression to a single target altitude, followed by a hold at that pressure for a defined duration: it corresponds to a standard commercial flight in a pressurized cargo hold. Procedure B applies a more gradual pressure change, with a controlled ascent and descent, to more closely reproduce an actual flight profile, including non-pressurized cargo holds or high-altitude ground transport.
| Simulated condition | Equivalent altitude | Approximate pressure |
|---|---|---|
| Pressurized cargo hold (commercial flight) | 2,400 to 4,600 m (8,000 to 15,000 ft) | about 56 to 75 kPa |
| Non-pressurized cargo hold | up to 4,900 m (16,000 ft) | about 55 kPa |
| Maximum altitude covered by the standard | up to 10,400 m (34,000 ft) | about 26 kPa |
In both cases, the test follows a similar sequence:
- Conditioning: specimens are stabilized in temperature and humidity, then closed or sealed as for an actual shipment.
- Placement in a vacuum chamber: the specimen is placed in a chamber capable of reaching the required pressure levels.
- Applying the pressure profile: simulated altitude ascent according to the chosen procedure A or B, then a hold at the target level for the specified duration.
- Return to ambient pressure and inspection: checking seal integrity, container deformation and any product leakage.
These tests require an instrumented, calibrated vacuum chamber able to precisely control both the depressurization rate and the vacuum level reached.
ASTM D6653 vs ASTM D4169: what’s the difference?
ASTM D6653 is often confused with ASTM D4169, which covers the entire distribution cycle of a package (vibration, shock, stacking, compression, handling…). In practice, it is frequently used as one specific step within a broader test plan based on ASTM D4169, dedicated solely to simulating the drop in atmospheric pressure. The two standards are complementary, not competing.
Which industries are affected?
- Food and beverage: vacuum-packed products, modified atmosphere packaging (MAP), beverages in flexible pouches.
- Pharmaceutical and medical devices: vials, ampoules, blister packs and infusion bags sensitive to pressure changes.
- Electronics: precision components and equipment that can be damaged by a pressure differential.
- Air transport and logistics: any air freight or express courier shipper looking to secure their packaging before it goes into circulation.

Frequently asked questions about ASTM D6653
What’s the difference between ASTM D6653 and ASTM D4169?
ASTM D4169 tests the entire distribution cycle (shock, vibration, compression), while this standard focuses solely on resistance to reduced atmospheric pressure. It is often used alongside, not instead of, ASTM D4169.
What equipment do you need for this test?
An instrumented vacuum chamber capable of reaching the required pressure levels and precisely controlling the rate of pressure ascent and descent.
Is this standard mandatory?
It is not a regulatory obligation in itself, but many customers and carriers require it contractually, particularly in the pharmaceutical and food industries, before approving packaging for air transport.
In summary
Complying with ASTM D6653 is not just a regulatory matter: it is a strategic choice to protect your brand, reduce returns and secure your air shipments. To set up these tests or get support choosing the right equipment, contact ACRN. Together, let’s make quality your standard.
