Whether you need basic integrity screening or a full retailer-specific simulation, we run the complete ISTA programme in-house. No subcontracting, no delays.
Basic performance screening for individual packages. Tests the strength and robustness of product-plus-package without simulating a specific distribution environment. Ideal as a benchmark or early-stage design screening tool.
Combines basic integrity elements with general simulation components like atmospheric conditioning and mode-shaped random vibration. A more thorough evaluation than Series 1, adding environmental factors to mechanical testing.
Full laboratory simulation of damage-producing motions, forces, and sequences encountered across vehicle types, routes, and handling exposures. The standard for validating real-world distribution performance.
Retailer-specific enhanced simulation testing. If you're an Amazon vendor needing ISTA-6 SIOC or Overbox certification, or meeting Sam's Club, Walmart, or Costco compliance requirements, we run these programmes daily and turn results around fast.
Don't need a full ISTA programme? We run each component individually - useful for design validation, troubleshooting, or non-standard requirements.
