Introduction

Modern cigarette manufacturing processes utilize numerous online metering instruments to monitor process parameters such as flow rate, temperature, moisture content, and pressure.

Testing is conducted, and the test data forms the basis for designing and adjusting production process parameters, implementing automated production control, and monitoring process quality. YC/T standards are formulated.

599 "Technical Specification for Online Measuring Instruments in Cigarette Processing" is designed to guide enterprises in comprehensively and systematically conducting measurement of online measuring instruments.

The technical work, YC/T 599, is proposed to consist of five parts.

--Part 1: General Principles. The purpose is to propose general procedures and requirements for online measuring instrument operations, while also outlining key aspects...

Recommended list of line measuring instruments.

--Part 2: Belt Scales. The purpose is to provide technical guidelines for conducting metrological work using belt scales specifically designed for tobacco products.
