TYPE TEST OF BOX TRAILERS – MEASURING THE “K” COEFFICIENT

Every transport vehicle used for international carriage of perishable foodstuffs requires an ATP certificate.

In order for an insulated box trailer to obtain this certificate, the manufacturer must perform a so-called type test of the prototype, during which the heat transmission coefficient “K” is measured.

If the “K” coefficient equals a maximum of 0.70 W/m2K, this is a box trailer with normal insulation that can be used for transporting refrigerated foodstuffs.

If the “K” coefficient equals a maximum of 0.40 W/m2K, this is a box trailer with reinforced insulation that can be used for transporting frozen foodstuffs.

The type test usually takes 24 hours and can be perform at our ATP test station.

It does not matter whether a refrigeration unit is installed on the box trailer, because the manufacturer subjects it to a type test separately.

The type test of the box trailer is valid for 6 years. However, if serial production exceeds 100 pieces within three years, the relevant authority (ATP test station) must determine which part of the manufactured box trailers shall be tested again.
