The Combination Compounding and Pill Counting Prescription Scale

In the early 20th century most drugs were compounded by the pharmacist using a scale designed for compounding prescriptions.  The National Committee on Weights and Measures (NCWM) saw the need for regulations to define the capabilities and characteristics of scales used for filling prescriptions by compounding.  The requirements were set down in Handbook 44 and sample scales were required to be submitted for evaluation by the National Type Evaluation Program (NTEP) for approval, which took the form of a Certificate of Compliance.
