Foreword

This standard is written in accordance with the rules given in GB/T 1.1-2009.

Introduction

Industrial Process Temperature Calibrator is an instrument with output and measurement functions that can simulate output and measure temperature signals (thermocouples, heat) Resistance), mainly used for calibration of temperature instruments. To unify the production and manufacture of industrial process temperature calibrators in China, standardize product performance requirements And inspection methods, it is necessary to standardize the industrial process temperature calibrator.

This standard specifies the product performance and inspection methods of industrial process temperature calibrators, for the specification of production, use and inspection industry. The process temperature calibrator provides reference and guidance.

1 Scope

This standard specifies the working conditions, general requirements, inspection methods, inspection rules, and industrial process temperature calibrators (hereinafter referred to as calibrators). Marking, packaging, transportation and storage.

This standard applies to desktop, portable calibrators.

This standard applies to AC powered, DC powered or battery powered calibrators.

Other instruments or equipment with partial temperature output and measurement functions can also refer to this standard.
