    accelerator mass spectrometry; biobased; biogenic; bomb carbon; 14C (carbon-14); carbon dating; isotope ratio mass spectrometry; liquid scintillation counting; new carbon; old carbon; percent modern carbon;;

    Rationale

    The standard contains a table (Table 1) with atmospheric reference D14C values to be used based on year and the value for 2020 is TBD. We need to provide an actual number to be used. This is the only edit being made at this time.
