01Name the distribution scenario
State whether the unit travels as a retail box inside a master carton, in an e-commerce overbox, through parcel delivery or on another route. ISTA procedures range from screening tools to general simulations, so procedure selection should follow the decision and shipment environment rather than a familiar test number.
02Freeze the packaged-product sample
Record product model, case, accessories, inserts, cable, manual, retail box, seals, protective film, dunnage and shipping carton. Use the intended quantities and production-equivalent materials. A test on an empty box or engineering substitute belongs in a separate screening record.
03Define acceptable condition first
Write what counts as product damage and what package degradation is allowed before testing. Include charging, pairing and basic function, case opening, earbud retention, accessory movement, box crushing, tears, seal opening, print scuff and retail presentation. Without limits, the same result can be called pass or fail after the fact.
04Control identification and sequence
Mark every face, edge and corner with a diagram. Record sample weight, dimensions, preconditioning, equipment, drop height or other level, orientations and order exactly as the selected method requires. For an internal screen, write the complete custom sequence and do not attach an ISTA name or certification claim.
05Inspect between and after test blocks
Photograph the package before testing and at agreed checkpoints. After the full sequence, inspect the retail box, seals, inserts, charging case, both earbuds and accessories. Run the defined functional checks and record damage location against the face-edge-corner diagram.
06Separate formal testing from factory screening
A simple factory screen can compare package versions when the method stays fixed. A formal claim should use the current complete procedure, suitable equipment, trained personnel and required reporting, often through an appropriate test laboratory. State which level of work was actually completed.
07Record correction and retest triggers
If the sample fails, record the observed path, probable mechanism, packaging change and new version. Retest when product configuration, weight, center of gravity, carton, insert, material, closure, supplier, packing process or distribution system changes in a way that could affect performance.
