Abstract
Attention is drawn to new vapor pressure equations which have been derived for4He and3He in terms of the Provisional 0.5 to 30 K temperature Scale (EPT-76). These equations should now be used in place of the T58 table for4He and the T62 equation for3He. Although the EPT-76 extends only to 0.5 K, the new3He equation is valid down to 0.2 K.
