Abstract

Overview

EN ISO 15212-1:1999 (ISO 15212-1:1998) - Oscillation-type density meters - Part 1: Laboratory instruments - sets out the metrological and technical requirements for oscillation-type density meters used in laboratories to measure homogeneous fluid samples. The standard covers instrument design, functional units, adjustment and calibration procedures, and type-test requirements. It is intended for manufacturers, testing and certification bodies, and laboratories performing density measurements or instrument calibration.

Key topics and requirements

Scope and purpose: Specifies requirements for laboratory oscillation-type density meters (stand-alone or integrated systems) and gives recommended methods for adjustment and calibration. It does not prescribe application-specific test procedures.
Functional units: Defines essential components - density sensor, excitation and control of oscillation, signal evaluation/display (density and oscillation frequency/period), temperature measurement, and malfunction detection. Optional units include sample thermostating, sampling and cleaning devices.
Sensor material and testing: Acceptable materials include borosilicate glass (ISO 3585), metals, alloys or plastics. A resistance test is specified: weigh a test-piece, immerse under intended conditions for 12 h, then clean and re-weigh; mass change
