1. Denomination of temperature units in gtr 15

Denomination of temperature units in gtr 15

2. Denomination of temperature units in gtr 15
Proposal based on DIN EN ISO for the use of Kelvin and Celsius
Define 0°C as 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
