1 Scope

This standard specifies the terms and definitions for equipment and pipeline insulation structure of the surface temperature of the test assessment, test methods, test requirements, test Organization and preparation, content analysis and evaluation of engineering quality test reports of data processing, the test uncertainty, thermal insulation effect. This standard applies to test and evaluate the thermal insulation effect of the general industrial sector equipment, pipes and accessories. Does not apply to construction, cold storage, Defense or scientific research, and some have special requirements for testing and evaluation of the thermal insulation effect.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 2588 General Equipment Thermal efficiency calculation GB/T 4132 insulation materials and related terms GB/T 4272 General technical equipment and pipeline insulation GB/T 6422 enterprise energy measurement and test guidelines GB/T 8175 equipment and pipeline insulation design guidelines

3 Terms and Definitions

GB/T 4132 and established the following terms and definitions apply to this standard. 3.1 Each point temperature inside the object does not change over time the heat transfer process. 3.2 Insulating structure surrounding the outer surface loss (or absorption) of heat flux or heat flux line. Test Method 4 4.1 Surface Temperature Testing Method 4.1.1 thermocouple method Sticking closely thermocouple directly on the outer surface of the insulating structure to measure its surface temperature method. This is a test surface temperature of the outer insulating structure The basic method of degree. 4.1.2 Surface thermometer method Thermocouple, thermal resistance and other surface thermometer sensor and the outer surface of the contact test structure to measure the insulation outer surface temperature method. This is a common method of testing insulating structure surface temperature will be measured according to the characteristics of different instruments outside of the surface of the insulating structure Performed measuring point processing and reading amendments, if necessary, be controlled by thermocouple method. 4.1.3 Infrared radiation thermometer method Infrared radiation thermometer aiming outer insulation test surface to measure its surface temperature method. Where the use of low temperature infrared radiation When the meter measurements, to correctly determine the measured surface thermal emissivity value and select a reasonable distance and emission angle. This method is generally applicable to the non-contact Measurement and measurement of the movement of objects.
