ATP classification

The agreement ATP (A – aqreement, contract, T – transport; P- perishable food) transportation are classified in accordance with their intended use and equipment and K coefficient (heat transfer coefficient).

The first letter indicates the type of means of transport:

• I – Insulated equipment
• F – Mechanically refrigerated equipment
• C – Heated equipment
• R – Refrigerated equipment
• B – Mechanically refrigerated and heated equipment
  

The second letter corresponds to the type of thermal insulation:

• R – reinforced insulation
• N – normal insulation

The third letter stands for the temperature class:

• A÷F – for insulated equipments
• A÷D – for refrigerated equipments
• A÷D – for heated equipment
• A÷L – for mechanically refrigerated and heated equipments

The letter X in the fourth position means that the transport vehicle is equipped with a removable or dependent thermal device.

Labels examples and their respective transport temperature ranges and heat transfer coefficients K:

• FNA – from +12°C to 0°C, k ≤ 0,7 〈W/m²K〉
• FRB – from +12°C to -10°C, k ≤ 0,4 〈W/m²K〉
• FRC – from +12°C to -20°C, k ≤ 0,4 〈W/m²K〉
