WEIGHING

Introduced: September 1968

Classification Context

Section:: PHYSICS
Class:: MEASURING; TESTING
Subclass:: WEIGHING

Description

G01G covers apparatus and methods for determining the mass or weight of objects through mechanical, electronic, or combined measuring systems. This includes weighing scales of all types—from simple balances and spring scales to sophisticated electronic load cells and digital weighing instruments used in commercial, industrial, laboratory, and domestic applications. The classification encompasses the design, construction, and operation of weighing mechanisms, as well as auxiliary devices for display, control, and data processing integrated with weighing systems. Related measurement of physical properties derived from weight (such as density or concentration determination by weighing) falls within this scope, though purely gravitational measurements are classified elsewhere in G01M or G01N.
