Why is peel strength of 12 N/25 mm the lower bound?

A: Below 12 N on a 25 mm strip, lap seams curl and shed lint across 300 wipes of 70% ethanol. A Veterinary portable diagnostic equipment box peels at floor, wall and lid edge.

How is lint judged after 300 wipes of 70% ethanol?

A: Under natural light the liner face must show no visible lint and no delamination; a fresh 25 mm strip at the end point still clears 12 N/25 mm.

How is divider shift of 1 mm measured after a 1.0 m drop?

A: Scribe a baseline along each divider edge before the drop, then read the slot gap with a feeler gauge; all five dividers of a Veterinary portable diagnostic equipment box are logged.

What do the 320 N handle and 360 N latches each govern?

A: 320 N is the handle-mount load while two 360 N latches lock the lid; both travel down through the wall ribs and keep separate pass criteria.

Why is the clearance of the five dividers set on its own?

A: A 1 mm clearance is the premise for a 1 mm shift, so a Veterinary portable diagnostic equipment box measures clearance at assembly before judging shift.

Quick answer: A Veterinary portable diagnostic equipment box needs a wipeable liner above 12 N/25 mm peel strength that survives 300 wipes of 70% ethanol lint-free.

FAQ

1. Divider Layout of a Veterinary Portable Diagnostic Equipment Box

Five dividers split the 440×310×170 mm cavity into separate zones, with the case measuring 500×370×230 mm outside and a 3.6 mm wall. A Veterinary portable diagnostic equipment box locates each divider through tongues on the inner wall: one long main panel, then the shorter side and end pieces, all seated to the same depth and held at the top by the lid frame.

The main panel runs the long edge, two side pieces and two end pieces fill the rest. Gaps stay at or below 1 mm, since a loose fit rattles in transit and a tight one crushes the liner. The empty case weighs 4.4 kg and carries 8.5 kg, divider mass already counted, and the panels neither warp nor leave their slots from −10 ℃ to 50 ℃.

Divider location	Count	Fixing	Clearance
Main panel	1 piece	Long-edge tongue	≤1 mm
Side panels	2 pieces	Wall slots	≤1 mm
End panels	2 pieces	Lid frame	≤1 mm
Total	5 pieces	Zoned location	≤1 mm

2. Peel Strength of the Wipeable Liner

Whether the liner stays bonded is read from peel strength. The wipeable face of a Veterinary portable diagnostic equipment box is set at or above 12 N/25 mm, the force to strip a 25 mm wide sample off the shell; below it, lap seams curl under 70% ethanol wipes and debris sheds.

Glue spread and cure set that value. An uneven coat drops peel strength first at the rounded corners; a short cure shows delamination within the earliest wipes. Sampling uses 25 mm strips peeled at the floor, the wall and the lid inner edge, and all three must clear 12 N/25 mm.

The wipe regime runs 300 back-and-forth cycles of 70% ethanol, logged at the start, midway and at the end. The wipeable face and the foam cells are treated apart: one is judged for lint, the other for a loose slot.

Wipe batch	Cumulative cycles	Lint observation	Peel retest
Start	0 cycles	Baseline face	≥12 N/25 mm
First stage	100 cycles	No lint	≥12 N/25 mm
Second stage	200 cycles	No lint	≥12 N/25 mm
End point	300 cycles	No lint	≥12 N/25 mm

3. Linting Assessment After Wipe Cycles

Linting is judged on the liner surface alone; divider slots follow the shift criterion instead. Inspection runs in natural light close to the wall, sweeping the lap seams, the rounded corners and the frame edge where fine debris shows first.

Once 300 cycles finish, no visible lint, no curled edge and no delamination is the pass. A fresh 25 mm strip at the end point must still clear 12 N/25 mm. JUNZHIJIA runs the 300 wipes and 3000 cycles on one sample batch during trials.

4. Measuring Divider Shift After a Drop

A 1.0 m drop is measured as the shift of all five dividers against the assembly baseline, with a pass at or below 1 mm. A Veterinary portable diagnostic equipment box scribes a mark along each divider edge before the drop, then a feeler gauge reads the slot gap piece by piece.

A shell short on stiffness lets the impact push dividers into the lid frame and the shift climbs. A 3.6 mm wall with local ribs keeps the wall from caving inward, since a caved wall throws the tongue location off.

Shift limit	When measured	Threshold	Record
Assembly baseline	Before drop	0 mm	Scribed divider edge
After drop	Right after 1.0 m	≤1 mm	Feeler gauge at slot
Cycle retest	After 3000 cycles	≤1 mm	Against baseline line
Handle loaded	Under 320 N	≤1 mm	Sight the divider edge

A Veterinary portable diagnostic equipment box takes a shift reading on each of the six drop faces.

5. Load Transfer from the Handle to the Case Walls

The handle is loaded at 320 N and two latches at 360 N each lock the lid to the case. Lifting a Veterinary portable diagnostic equipment box at its full 8.5 kg puts a point load on the handle mount, and anchoring that straight into a 3.6 mm wall blanches the surrounding material.

Force travels from handle to mount insert, to wall ribs, to the shell, and is carried by the whole case; after 3000 cycles the latches still hold at the 360 N order.

Assembly records the clearance of all five dividers first. Only a reading inside 1 mm lets the batch move on. The 1.0 m drop stage measures shift on each divider. The 70% ethanol stage runs 300 wipes before a fresh 25 mm peel test. The 3000-cycle stage rechecks latches and the handle mount. Four stages keep separate logs, and a missing one blocks the verdict.

Conclusion

A Veterinary portable diagnostic equipment box splits the job into a wipeable liner and a zoned interior. The liner holds at or above 12 N/25 mm through 300 wipes of 70% ethanol without lint, while five dividers shift no more than 1 mm after a 1.0 m drop; a 320 N handle and two 360 N latches carry load through the walls after 3000 cycles. Log clearance, peel and shift in that order.
