Introduction

In order to standardize the energy efficiency measurement and inspection of water storage electric water heaters that implement energy efficiency labeling management, the requirements of JJF 1261.1-2017 Energy Efficiency Measurement and Testing Rules for Energy Products have been established.

This specification replaces JJF 1261.16-2015, compared with JJF 1261.16-2015, except for editorial changes.

The main changes are as follows.

--- The name of the specification is changed from "Regulations for measuring the energy efficiency of storage-type electric water heaters" to "Storage-type electric heaters Water energy efficiency measurement and detection rules";

--- "5.1 energy efficiency labeling" adds "energy efficiency information code" and "energy efficiency 'leader' information", etc.

Claim.

--- The original record and test report format were revised accordingly (Appendix C, Appendix D).

The previous versions of this specification were issued as follows.

---JJF 1261.16-2015.

Storage water heater energy efficiency Metering detection rules

1 Scope

This specification specifies the energy efficiency of domestic and similar water storage electric water heaters (hereinafter referred to as electric water heaters) Measurement requirements, test conditions, measurement and testing procedures, measurement and testing items and methods, and criteria for the assessment of measurement results Test report and other content.

This specification is applicable to the measurement and supervision of the energy efficiency of electric water heaters. Commissioned inspections can be conducted with reference to this specification. produce Units that sell electric water heater products can also be tested in accordance with this specification.

This specification applies only to domestic and similar water storage electric water heaters. This specification does not apply to auxiliary heating New energy water heaters, heat pump water heaters. The electric water heater that is tested should be a product that the manufacturer has passed its own inspection, or it is a commodity that the seller imports and sells.
