Distribution Testing Services

ASTM Simulated Distribution Testing

Laboratory distribution simulation testing provides a uniform and repeatable way of evaluating packaged products and packaging designs by utilizing standardized equipment and procedures to subject the packaging to anticipated hazards that may occur with routine distribution of packaged products. Our package testing laboratory provides drop (shock), random vibration, loose load vibration and compression testing.

ISTA Transit Testing & Certification

ISTA testing goes beyond basic package strength tests. It replicates the vibration, shock, compression, and climatic conditions a package will encounter during transportation. Our team applies a variety of standardized test profiles design for various product categories and shipping environments, which we offer guidance to select the most appropriate profile for your product and packaging configuration.

Climatic Stressing & Freeze/Thaw Simulations

Environmental conditions vary depending on distribution channel, pathway, and provider, which is why our testing simulates extreme temperatures, humidity, and pressure fluctuations to prepare for effective storage and transportation. Partnering with our team to perform this testing helps ensure your product’s quality and safety, reduce risk of recalls, and provide data for regulatory compliance.

Thermal Qualification for Cold Chain Shipments

Maintaining product efficacy in cold chain shipments must be verified with thermal qualification testing. Shipping test evaluations ensure temperature-sensitive medical devices and drug products maintain potency and functionality throughout the logistics process. Our team provides the guidance and testing necessary to satisfy regulatory requirements and mitigate risks of compromised products.

Visual Inspection

Performance of the packaged product is typically assessed by 100% visual inspection. The specifics of the visual inspection procedure, the detail to which observations are documented, and the specific acceptance criteria may be established by a client protocol. Protocol drafting services are also offered by our experts.

Dimensional Analysis

Verify that critical dimensions are maintained for your product or packaging after simulated distribution testing. Our lab uses calipers, optical comparators, micrometers, and other measurement equipment to confirm that your materials comply with their specifications.

Package Performance Testing


Package strength testing generally refers to the package seal quality. Package strength concerns the force required to separate two components of the package. It could be the force to separate two flexible components of a pouch, or a flexible lid and a thermoform tray, or a measure of the compressive force exerted by an elastomeric closure onto a parenteral vial finish after capping. These forces may be measured in pounds per inch width, as in the seal/peel test per ASTM F88; or in pounds per square inch, as in package burst testing methods. Alone, these tests of package strength values do not necessarily prove the integrity of the entire package but serve to characterize and monitor package seal quality.


In the life sciences community, the term package integrity has many meanings. For medical device manufacturers complying with ISO 11607, package integrity is synonymous with sterile barrier system (SBS) packaging integrity test methods. For drug product manufacturers, package integrity of parenteral packaging is the ability of a sterile product closure system to keep product contents in, while keeping detrimental environmental contaminants out. Such contaminants may include microorganisms, reactive gases, and other substances. The product includes the pharmaceutical formulation as well as the package headspace – which may consist of ambient air or nonreactive gases with a specified water-vapor content, under full or sub atmospheric pressure levels. 

Sterile, parenteral package integrity is often referred to as Container Closure Integrity Testing, while medical device manufacturers refer to test methods for sterile barrier maintenance simply as Package Integrity Testing.

At the heart of effective and sustainable packaging design and performance are the component materials. The physical properties, and sometimes chemical properties, of the packaging materials need to be well understood by packaging engineers to aid in the design process. We offer a wide variety of testing options when it comes to testing packaging materials. Capabilities include physical strength testing, packaging material qualification and identification, and characterizing material response to fatigue. Information gathered from these tests helps plan the optimal packaging material choice in specific applications.


Label legibility is of principle concern to pharmaceutical and medical device manufacturers. Our team evaluates your product labels for adhesion properties and abrasion resistance through temperature / humidity exposure of applied labels, peel resistance and abrasion resistance.

Common methods include:

      • ASTM D6252, Peel Adhesion of Pressure-Sensitive Label Stocks at a 90° Angle
      • ASTM D6862, 90 Degree Peel Resistance of Adhesives
      • ASTM D3330, Peel Adhesion of Pressure-Sensitive Tape
      • ASTM D2979, Pressure-Sensitive Tack of Adhesives Using an Inverted Probe Machine
      • ASTM D6195, Loop Tack
      • FINAT Methods #1 – #9
      • ASTM D5264, Abrasion Resistance of Printed Materials by the Sutherland Rub Tester
      • PSTC Methods
      • Attribute Inspections over Time
