Introduction

In order to standardize the energy efficiency measurement and testing of domestic gas cookers that implement energy efficiency label management, JJF 1261.1-2017 The requirements of the Energy Efficiency Measurement and Measurement Rules for Energy Products are formulated. This specification is the first release. Household gas cooker energy efficiency Metrology detection rules

1 Scope

This specification specifies the measurement requirements for energy efficiency of household gas cookers, measurement and testing procedures, measurement and detection methods, Measurement criteria and test reports. This code is applicable to the energy efficiency measurement supervision and testing of household gas cookers, and the entrusted inspection can refer to this specification. Row. Units that produce and sell domestic gas cookers can also be tested with reference to this specification. This specification is applicable to household combustion with a rated burner heat load of not more than 5.23 kW for a single burner using only town gas. Gas cookers are not suitable for use in gas cookers used in mobile transport vehicles. The domestic gas cooker to be tested shall be the product that the producer has passed the self-test, or the seller shall import or sell. commodity. The gas referred to in this code refers to the provisions of GB/T 13611-2018 "Classification and Basic Characteristics of Town Gas" Gas.

2 reference files

This specification refers to the following documents. JJF 1261.1-2017 energy efficiency measurement and testing rules for energy products GB/T 2829-2002 Periodic inspection count sampling procedures and tables (applicable to the inspection of process stability) GB/T 12206-2006 Method for determination of calorific value and relative density of town gas GB/T 13611-2018 Classification and basic characteristics of town gas GB 16410-2007 Household gas cooker GB 30720-2014 Domestic gas cooker energy efficiency limit value and energy efficiency rating For dated references, only dated versions apply to this specification; undated quotations The latest version (including all amendments) applies to this specification.

3 terms and units of measure

The following terms and definitions defined in GB 16410-2007 apply to this specification. 3.1 Reference state referenceconditions The dry gas state at a temperature of 15 ° C and an absolute pressure of 101.3 kPa. 3.2 rated heat load (rated heat flow) nominalheatinput The manufacturer's mark is used under the rated gas supply pressure, and the reference gas at the reference state is used for the domestic gas cooker. The design value of the heat load, measured in kW. 3.3 measured thermal load actualheatinput In the detection state, the product of the low calorific value of the detected gas and the measured gas flow rate is measured in kW. 3.4 measured conversion heat load convertedactualheatinput The product of the designed low calorific value of the gas and the calculated value of the measured gas flow converted to the reference state, the unit of measurement
