pH measurement - Specification for pH scale Ingestion-build-276583 BS EN IEC 61853‑4 describesWhat is BS 1647 1 pH scale about? BS 1647 discusses pH measurement. BS 1647 1 is the first part of the BS 1647 multi series and discusses specifications for pH scale. BS 1647 1 specifies requirements for a pH scale in terms of a single reference value standard aqueous solution of potassium hydrogen phthalate with a molality of 0. 05 mol kg, and the (theoretical) slope factor. This pH scale is appropriate for pH measurements of aqueous solutions at
