Additional Validations and Variations

Addition of truck body ATP IR standards with UT-1200 Spectrum S3+S3

2 zones multi-temperatures truck body ATP IR standard with a 0.40 W/m² K insulation or better with UT-1200 Spectrum S3+S3 is approved in parallel because it offers better insulation and ensure equivalent temperature management.

Addition of Whisper Option for T-1000R Spectrum and T-1200R Spectrum

T-1000R Spectrum S3+S3 Whisper and T-1200R Spectrum S3+S3 Whisper are approved in parallel.

Addition of rear rolling doors in lieu et place of double rear doors

If K factor co-efficient remains below 0.40 W/m² K and therefore the vehicle is FRC declared, body equipped with rear rolling doors instead of double rear doors are approved in parallel.

Variations on body sizes

Smaller body sizes appropriate to the unit design are also included because the performance will be improved as body size reduces:

• T-1000R Spectrum S3+S3 and T-1200R Spectrum S3+S3 should not be used on a body volume that is less than 45m³ and not more than 57m³; this would require a different specification unit.

• UT-1200 Spectrum S3+S3 should not be used on a body volume that is less than 43m³ and not more than 54m³; this would require a different specification unit.
