Transport Simulation β€” ISTA 2A, Part 2 - Compression Testing

πŸ‘‰ What is Compression Testing? 

Compression risks are about the most frequent concerns that products and containers experience during the logistics chain. Compression Testing is used to assess the resilience of shipping units when faced with compressive stresses (forces pushing across opposite ends of a parcel). Compression testing is essential for the design of a suitable and efficient packaging that can work in presence of transport risks.


In ISTA 2A, the standard calls for Compression Testing. During Compression Testing, the machine measures the mouvement of the plates compressing the packagin, and the total compression force.


ISTA 2A’s Atmospheric Conditioning follows the ATSM D4332 Standard. 



πŸ‘‰ What is Packaging Validation?

The validation of packaging stems from the need to ensure the quality of products across the many steps in your distribution cycle: from shipping & storage to final user. It is a common requirement for many product categories, including a strong emphasis on the packaging quality requirements for the medical and pharmaceutical industries.



πŸ‘‰ What are the types of Packaging Validation? 

Packaging Validation for medical devices & pharmaceutical goods is segmented into three categories. 

βœ… Environmental Conditioning

βœ… Transport Simulation (or also known as Transit Testing) 

βœ… Integrity Testing (or also known as Sterile Barrier Integrity Testing) 



πŸ‘‰ What is ISTA 2A?

The ISTA 2A Transport Simulation standard is designed to evaluate ready-to-ship packed items weighing up to 68kg.

ISTA 2A standard tests a packaging system's ability to withstand the physical stress of transportation throughout the product’s supply chain to the final users. The standard is issued by the International Safe Transport Association (ISTA), an organisation devoted to understanding the expectations of secure transport services.



πŸ‘‰ What is ISTA 2A’s test sequence? 

ISTA 2A is composed of 4 testing types: 

1️⃣ Atmospheric Conditioning

2️⃣ Compression Testing

3️⃣ Vibration Testing

4️⃣ Shock & Drop Testing



πŸ“¦ According to ISO 11607-1

ISO 11607-1 specifies the requirements related to the compliance of the packaging for sterilised medical devices, including materials, sterile barrier systems and packaging systems.
