The most time-consuming part of planning a mixed load is assembling which product travels at which temperature. The ATP Roadside Inspection Guide of Turkey's Ministry of Transport and Infrastructure prepared that list for inspectors. The temperatures come from Annexes 2 and 3 of the ATP Agreement, and the marking classes beside them show which equipment may carry the product.
| Frozen product | Maximum | ATP marking class |
|---|---|---|
| Ice cream | -20 °C | FRC, RRC, BRI-BRL |
| Frozen fish and seafood, all quick-frozen foods | -18 °C | same |
| All other frozen foods | -12 °C | same |
| Butter (margarine in the Turkish guide) | -10 °C | FRB, FRC, RRB, RRC, BRE-BRL |
| Chilled product | Maximum |
|---|---|
| Red meat, offal excluded | +7 °C |
| Raw milk | +6 °C |
| Meat products, pasteurised milk, butter, fresh dairy, ready-cooked food, ready-to-eat raw vegetables, concentrated fruit juice | +6 °C or the temperature on the label |
| Poultry, rabbits, small game | +4 °C |
| Offal | +3 °C |
| Minced meat | +2 °C or the temperature on the label |
| Untreated fish, molluscs and crustaceans | Temperature of melting ice |
On the chilled side the guide accepts every refrigerated class: FNA, FRB, FRC, RNA, RRB, RRC, BNA and BRA-BRL, including those with the X suffix. Two rows also allow the temperature written on the label or transport documents instead of +6 or +2 °C, which is why the label is the first place to look in any dispute over a shipment.
Set the numbers side by side and the decision to be taken about carrying different temperatures on one trip becomes concrete.
Three practical conclusions follow from the table:
- Red meat and minced meat are 5 degrees apart. If both go in one vehicle they need separate compartments or containers; if the order misses that, a pallet stays on the dock.
- Ice cream is the coldest row and needs a class that holds -20 °C: FRC, RRC or BRI-BRL. On the frozen side, class B, which reaches -10 °C, covers only the butter row.
- Untreated fish travels in melting ice, around 0 °C, the narrowest band on the chilled side.
The same table applies to vehicles holding the domestic perishable-goods carriage document (BTB); in the guide's own example, products carried under FRC may also be carried under T-FrC.
