While some of the content in this section Already exists in some national or international standards, but this part of the existing standards were consolidated and adds a lot of content. GB/T 32348.2-2015 provides detailed recommendations for industrial and commercial electricity heating system design, installation and maintenance. Objective GB/T 32348 is through the following provisions, the resistance trace heating systems in normal use, should be able to use under the conditions specified in its Safe for work. a) the use of rational structure of the heater and meet the test criteria specified in detail in this section. This structure includes a metal sheath, braid Layer shielding conductive jacket or equivalent; b) in the design, installation and maintenance, according to GB/T 32348.2-2015 its work on a safe temperature; c) at least a minimum level of overcurrent and earth fault protection in this section and GB/T 32348.2-2015 requirements. Industrial and commercial use resistive heating system Part 1. General and testing requirements1 ScopeGB/T 32348 provisions of this part of the resistive heating system requirements, including general testing requirements. This section applies heat tracing systems include factory-assembled or on-site (site) assembled units, it may be already set in accordance with the manufacturer's instructions Loading and/or in series and in parallel with the hot surface of the heater or terminated (with heating pads and hot plate). This section also includes a method for terminating components and control systems with the use of heat tracing requirements. This section provides the basic requirements and test methods for industrial and commercial use resistive heating device suitable. Under this section by the certified products Have received appropriate technical training of personnel to install, and can only be done by specially trained key personnel, such as joints and terminations The mounting member. Installation should be carried out under the supervision of highly resistive heating system additional training of qualified personnel. This section does not apply to any potentially explosive atmosphere applications. This section does not involve induction, impedance or skin effect heating. Heating system can be divided into different types of applications under different conditions after installation and installation need to meet different test requirements. Heating system usually certified by a particular device or application type. Typical applications of different types of devices include, but are not limited to. a) pipes, vessels and equipment for heating surface heating device applications include. --- Freeze protection and temperature; --- Hot water pipes; --- Petroleum and chemical pipeline; --- Main pipe sprinkler systems and water pipes. b) outdoor open space with a heating device applications include. --- Roof de-icing; --- Drains and sewers de-icing; --- Sediment basins and drainage systems; --- A heating rail). c) with embedded heating device applications include. --- Snow; --- Frost protection; --- Warm; --- Energy storage system; --- Doorframe. d) within the tubing and piping heating devices, applications include. --- Snowmelt (in conduit); --- Frost protection (in conduit); --- Warm (in conduit); --- Energy storage system (in conduit); --- Drinking water pipes freezing internal heating; 1) requires further evaluation to clarify some special application conditions, such as the applied voltage fluctuations and voltage peaks. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32348.1-2015_English be delivered?Answer: Upon your order, we will start to translate GB/T 32348.1-2015_English as soon as possible, and keep you informed of the progress.
