Denomination of temperature units in gtr 15 WLTP-09-19e Denomination of temperature units in gtr 15 M. Bergmann, AUDI

Denomination of temperature units in gtr 15 Proposal based on DIN EN ISO 80000-5 for the use of Kelvin and Celsius Define 0°C as 273.15 K (already done) Where possible, use “°C” for the definition of temperatures in the gtr Attention: Use Kelvin (with .15) in calculations, where possible/necessary Delete redundant information: ± 5 K (± 5 °C ) (Example) Example: Temperatures with tolerances written as (e.g.): Old: 303 K ± 10 K (30 °C ± 10 °C) New: 30 °C ± 10 °C M.
