ISO 21848 Calibration of High-Accuracy Pressure Sensors

Comprehensive Guide to ISO 21848 Calibration of High-Accuracy Pressure Sensors Laboratory Testing Service Provided by Eurolab

ISO 21848 is a widely recognized international standard for the calibration of high-accuracy pressure sensors. This standard is published by the International Organization for Standardization (ISO) and provides guidelines for the calibration process, including the selection of test equipment, sampling procedures, and measurement methods.

The legal and regulatory framework surrounding this testing service is governed by various national and international standards. In Europe, for example, the European Unions Machinery Directive 2006/42/EC requires that pressure sensors be calibrated to ensure their accuracy and reliability. Similarly, in the United States, the Occupational Safety and Health Administration (OSHA) regulates the use of pressure sensors in industrial settings.

The relevant national standards that apply to this specific laboratory test include:

These standards specify the requirements for pressure sensors, including their accuracy, repeatability, and calibration procedures. The standard development organizations that play a crucial role in this process include:

Standards evolve over time to reflect changes in technology, regulatory requirements, or industry practices. For example, ISO 21848:2018 is a revised version of the standard that includes new calibration procedures and measurement methods.
