ISO 6243WMO Guide to Meteorological Instruments and Methods of Observation, No.8.,6th Edition, 1996
被代替标准
ISO/FDIS 15927-6-2007
适用范围
This part of ISO 15927 specifies the definition, method of computation and method of presentation of data on
accumulated temperature differences, used for assessing the energy used for space heating in buildings.
These are normally expressed in degree-hours or degree-days, and such data are often referred to simply as
“heating degree-hours” or “heating degree-days”.
This part of ISO 15927 includes approximate methods for calculating accumulated temperature differences
based on hourly or daily mean temperatures and for estimating monthly values to any base temperature, for
use when data computed directly from meteorological air temperature records are not available.
In some countries, a threshold temperature different from the base temperature is used. This part of
ISO 15927 does not cover this.
