Drop Testing

Drop testing at Gaynes Labs evaluates the ability of packages, containers, and products to withstand the impacts of handling, transportation, and distribution. Testing is performed using controlled free-fall and rotational drop methods across a wide range of package sizes and weights. We are able to drop products ranging from small retail cartons to large industrial containers including drums, IBCs, and electric vehicle battery crates.

Drop Testing Applications

Gaynes Labs performs drop testing for manufacturers, packagers, and distributors across a wide range of industries and container formats.

Medical Devices & Healthcare
Drop testing is a required element of ISTA and ASTM distribution simulation for medical device packaging validation. Gaynes Labs performs the controlled drop sequences required for FDA-recognized distribution validation across parcel and LTL channels.

E-Commerce & Retail
Carrier and retailer certification programs require specific drop sequences at defined heights and orientations. Gaynes Labs performs drop testing in support of ISTA 6-Amazon.com SIOC, ISTA 6-Amazon.com Over Box, ISTA 6-FedEx-A, ISTA 6-FedEx-B, ISTA 6-SamsClub, and ISTA 3A for USPS parcel compliance.

Chemicals, Agriculture & Industrial
UN/DOT certification under 49 CFR requires drop testing of drums, pails, jerricans, fiberboard boxes, and IBCs at drop heights determined by packing group. Gaynes Labs performs the full 49 CFR 178.603 drop test protocol for non-bulk packaging and 49 CFR Part 178 Subpart O for IBC qualification and periodic revalidation.

Automotive & Electric Vehicles
Large-format lithium ion battery packs and EV battery crates classified as UN3480 or UN3481 under 49 CFR 173.185 require packaging that can demonstrate impact resistance and protection during transport. Gaynes Labs performs drop testing on protective enclosures, wooden slatted crates, and outer packaging used for lithium ion battery shipments, supporting compliance with DOT hazmat transport requirements for EV and industrial battery manufacturers.

Consumer Products & General Manufacturing
Packaging engineers and product developers use drop testing to identify failure modes, validate designs, and qualify new packaging before production launch. Gaynes Labs performs ISTA 1-series screening drops for early-stage design evaluation and full ISTA 3-series and ASTM D4169 drop sequences for distribution validation.

Packaging Manufacturers & Designers
Corrugated manufacturers, contract packagers, and packaging engineers use independent drop testing to validate new designs against customer specifications and distribution requirements. Gaynes Labs provides the independent third-party drop test documentation required for customer approval programs and retailer compliance.

Frequently asked questions

What drop heights are used in drop testing, and how are they determined?

Drop heights in controlled testing are not arbitrary, they are specified by the standard. For ISTA protocols, drop height generally decreases as package weight increases. For UN/DOT certification, drop heights are generally determined by packing group. ASTM drop heights are similarly weight-based and aligned with the distribution program parameters. Drops are typically performed in multiple orientations (face, edge, and corner) to evaluate the package from the angles most likely to cause failure in real-world handling. We are able to help you determine the applicable drop height and procedure based on your package characteristics and standards being followed.
