Notes

  1. Jump up Commercially available lithium materials have atomic weights that range between 6.939 and 6.996; if a more accurate value is required, it must be determined for the specific material.
  2. Jump up Within the European Union, the following additional hazard statement (EUH014) must also be displayed on labelling: Reacts violently with water.
