What is an ISTA lab?
An ISTA lab is a testing laboratory certified by the International Safe Transit Association to run its published transit-simulation procedures and issue reports against them. Megalab is an ISTA certified lab in Aurora, Ontario, and holds ISO/IEC 17025 accreditation from A2LA covering the ISTA 1, 2, 3, 4, 6 and 7D series.
ISTA procedures are fixed sequences rather than plans you assemble. You pick the one that matches your distribution channel, your weight and your package configuration, then run it as written. 3A covers parcel shipments up to 150 lb, 3B covers less-than-truckload, and the 6-series carries the retailer and carrier programs: 6-Amazon, 6-FedEx and 6-SAMSCLUB. That fixed-sequence design is the main practical difference from ASTM D4169, which builds a plan from a menu of schedules.
Which ISTA procedure do you need?
The series tells you how hard the test presses, and the number after it tells you the shipping channel. Most people land on 3A. If you are not sure, send the weight and the route and we will name it for you.
The one most buyers mean. General simulation for an individually packaged product moving through a courier network, up to 150 lb. Four package types, and the type changes the sequence.
Freight, not parcel. Less-than-truckload shipments, with four separate paths depending on whether the load is standard, cylindrical or palletized.
A full load of identical units. Unitized loads of the same product shipped as a truckload, where stacking and vehicle vibration matter more than individual handling.
A mixed pallet into a distribution centre. The retail supply chain procedure, for product travelling to a DC on a pallet with other items rather than on its own.
A step below the 3 series. Adds one element of real distribution to the basic integrity tests. A budget route when nobody has specified a 3-series procedure.
Design screening, not a simulation. Challenges basic strength and durability with no simulated hazard. Useful early in development, and never a substitute for a 3-series requirement.
Retailer and carrier programmes sit in the 6 series and are named after the retailer rather than numbered. Those are covered at Amazon, FedEx and Costco package testing.
Where to find an ISTA certified lab in Ontario
Megalab is in Aurora, about 40 minutes north of downtown Toronto, which puts most of the Greater Toronto Area, Kitchener-Waterloo and the Highway 401 corridor within a same-day courier run. That matters more for package testing than for most lab work, because the samples are bulky. A palletised unit load or a set of five fragile-product replicates is a freight shipment, and shipping it across a border adds days to the schedule and customs paperwork to the file before any testing starts.
What to check when you compare labs. First, that the specific procedure you need is named on their ISO 17025 scope, rather than the ISTA series being referred to in general. Megalab's A2LA scope names the ISTA 1, 2, 3, 4, 6 and 7D series, so an accredited report covers the retailer programs as well as the general simulation procedures. Second, whether the drop, vibration and compression equipment is in house or subcontracted, because that decides your turnaround. Ours is in house.
Third, ask what happens when the package fails. A test report that says “fail” and stops is worth very little. What you want is the failure mode, the hazard element that caused it, and a view on what to change before the retest. Tell us the channel, the weight and the package configuration and we will tell you which procedure applies, usually the same day.
Related package testing
If your customer’s spec names ASTM rather than ISTA, start at ASTM D4169 package testing. Shipping through a parcel network? The procedure is almost always ISTA 3A. For less-than-truckload freight it is 3B, for a uniform truckload 3E, and for a mixed retail pallet 3F. Below the simulation procedures sit 2A and 1A. The two are not interchangeable, and our guide to choosing between ISTA and ASTM D4169 covers which one a given buyer usually means.
Where a retailer or carrier has named its own program, go straight to Amazon, FedEx or Costco package testing. All of them sit under package testing services.
Frequently Asked Questions
Common questions about ISTA testing and ISTA certified labs.
A laboratory certified by the International Safe Transit Association to run its published procedures and issue reports against them. Megalab is an ISTA certified lab in Aurora, Ontario, with the ISTA 1, 2, 3, 4, 6 and 7D series on its A2LA ISO/IEC 17025 scope.
International Safe Transit Association. It is a non-profit member association that develops and publishes transit-simulation test procedures for packaged products, and certifies the laboratories that run them.
Two different things go by that name, and they are worth separating. A laboratory becomes ISTA certified by joining ISTA and meeting its laboratory requirements. A package is not certified in the same sense. It passes a named procedure, and the lab issues a test report stating which procedure was run and the result.
Some ISTA programs do carry a mark, and those run through their own separate program with its own audit. If your customer has asked for a mark rather than a report, send us the exact wording and we will tell you which route it points at.
They are grouped in series of increasing severity. The 1-series is screening only, with no simulated hazard. The 2-series is partial simulation. The 3-series is the general simulation work most buyers mean, including 3A for parcel shipments up to 150 lb, 3B for less-than-truckload and 3E for unitized loads. The 6-series carries the retailer and carrier programs, among them 6-Amazon, 6-FedEx and 6-SAMSCLUB. The 7-series covers thermal and development testing.
A 1-series pass does not substitute for a 3-series requirement, even at the same weight. Tell us the distribution channel and the package weight and we will point you at the right one.
ISTA gives you a fixed sequence. You choose the procedure that matches your channel, weight and configuration, and run it exactly as published. ASTM D4169 gives you a menu instead, and you assemble a Distribution Cycle from schedules and pick an Assurance Level, which makes it flexible but means nothing is defined until those choices are made.
In practice the buyer decides. Retailers and carriers tend to name an ISTA procedure, while industrial, aerospace and government customers tend to write D4169 into the spec. Our guide to choosing between ISTA and ASTM D4169 goes through it in more detail.
