GB/T 25967-2010Test methods for thermal performance of domestic solar-plus-supplementary water heating systems (English PDF)

Foreword

This standard is based on the actual situation of China's solar water heating system product development to prepare the standards with reference to the European standards EN12976-1.2006 "system of solar thermal systems and components manufacturing plants - Part 1. general requirements" and EN12976-2. 2006 ". Test methods - Part 2 of solar thermal systems and system components factory-made use of." Appendix A of this standard is a normative appendix. This standard by the National Standardization Technical Committee of solar energy (SAC/TC402) and focal points. This standard was drafted.

Domestic solar water heating system with auxiliary energy Thermal performance test method

1 Scope

GB/T 25967-2010 is the Chinese national standard on test methods for thermal performance of domestic solar-plus-supplementary water heating systems, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 10 January 2011 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2011. Classification: ICS 27.160, CCS F12. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies thermal performance test method of household solar water heating system with auxiliary energy under outdoor conditions. This standard applies to domestic solar water heating system, hot water storage tank with a volume of 0.6m3 less auxiliary energy.
