GB/T 40233-2021Ergonomics of the thermal environment - Instruments for measuring physical quantities (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is equivalent to the adoption of ISO 7726.1998 "Ergonomics of Thermal Environment Physical Quantities Measuring Instruments".

The Chinese documents that have a consistent correspondence relationship with the normatively cited international documents in this standard are as follows.

---GB/T 18049-2017 Ergonomics of thermal environment through calculation of PMV and PPD index and local thermal comfort criteria

Analysis, measurement and interpretation of thermal comfort (ISO 7730.2005, IDT)

This standard has made the following editorial changes.

---Adjusted the number of formulas in the appendix according to the specification.

This standard was proposed and managed by the National Ergonomics Standardization Technical Committee (SAC/TC7).

Introduction

This standard is one of a series of documents applied to the ergonomics research of thermal environment.

This series of standards mainly involves the following aspects.

---The final clauses can be used in measurement methods, experiments or annotations that already exist or are being drafted;

--- Formulate specifications for related physical quantity test methods that describe the characteristics of the thermal environment;

---Provide several options for explaining parameters;

---The recommended value or limit value of the thermal environment suitable for standard comfortable environment and extreme environment (including heat and cold);

---Standardize the test method of individual or collective heating (cold) protection device and the effect of the process.

Any measuring instrument that can meet (or exceed) the accuracy required by this standard can be used.

The appendix introduces some recommended instruments for physical quantity measurement. The characteristics of these instruments will be based on the measurement principle, structure, and use method.

The style is different. Users can also compare the accuracy of related instruments and equipment on the market, and check that they meet the requirements of this standard.

The equipment can be used.

Ergonomics physical quantity measuring instrument for thermal environment

1 Scope

This standard specifies the basic characteristics and measurement methods of thermal environment physical quantity measuring instruments.

This standard is to standardize the recording of test data, thereby defining some indicators. These definitions do not involve specific comfort or heat stress.

index.

This standard applies to.

a) Specifications for the manufacture and equipment use of environmental physical quantity measuring instruments;

b) Both parties draw up relevant contracts for measuring these physical quantities.

This standard applies to the effects of hot, mild, comfortable or cold environments on the human body.
