ATP splits insulation by the k coefficient: at most 0.70 for IN and 0.40 W/m²K for IR. IR is mandatory for the sub-zero refrigerated classes.

The tub, bar and cross on the care label show what temperature a machine may use. A bag with a rigid base or brittle insulation stays out of the machine, whatever the label says.

A box with no motor and no power needs inspection in place of maintenance: four lists, daily, monthly, half-yearly and annual, plus the ATP date on the same calendar.

The same bag gives a different time when fill, product temperature, ice packs and openings change. One logged trial on your hardest route gives your own hours.

Document damage location, layer impact and cleanability; confirm the repair method with authorized service.

The ATP definition of insulated equipment, its K-value classes and a six-hour route calculation show where a soft bag stops being enough. Product temperature limits come from the same ATP guide.

Do not assume every box can be stacked; verify model instructions, support points and warehouse rack capacity.

Container payload does not rate an internal grid or shelf; check the document and loading arrangement.

Compare removability, cleaning, plate fit and loading arrangement for the exact configuration.

Match pre-cooling, plate and cleaning steps to the model and product conditions.

Do not assume a fixed duration; match model instructions, surface readings and loading time.

The eutectic plate comes out of the container and is washed by hand at a separate bench. After washing, the filling has to freeze through again, and the plan is built on the 24-hour freezing time in the GEBHARDT table.

Washer capacity alone does not set the limit; verify the setting against the container manual.

Do not infer acid effects from a general rule; confirm coating type and product instructions in writing.

Choosing a detergent looks like a hygiene decision. It is really a decision about how long the galvanised metal parts of the box will last; the limit is set by the product and its concentration as well as by pH.

Do not assume unlimited life; track plate condition, maker instructions and removal reasons.
