Introduction

In order to regulate the implementation of energy efficiency logo management of domestic solar hot water systems (hereinafter referred to as home solar energy) The energy efficiency measurement and inspection work is based on the JJF 1261.1-2017 Energy Efficiency Measurement and Detection Rules for Energy-using Products. Requirements, the development of this specification. This specification replaces JJF 1261.11-2013, compared with JJF 1261.11-2013, except for editorial modifications. The main changes are as follows. --- The name of the specification was changed from "Household solar hot water system energy efficiency identification measurement and measurement rules" to "Home use too Yangneng Hot Water System Energy Efficiency Measurement and Detection Rules; --- "5.1 energy efficiency labeling" to increase "energy efficiency information code" and "energy efficiency 'leader' information", etc. Claim; --- The original record format and test report format were revised accordingly (Appendix E, Appendix F). The previous versions of this specification were issued as follows. ---JJF 1261.11-2013. Domestic solar hot water system energy efficiency measurement and detection rules
