Introduction

GB/T 15470, "Performance Test Methods for Direct-Acting Room Electric Heaters for Households," aims to standardize the performance of direct-acting room electric heaters.

The performance testing method is proposed to consist of the following three parts.

---Part 1: General Requirements. The purpose is to specify the performance testing methods for household direct-acting room heaters.

---Part 2: Additional Regulations for the Measurement of Radiation Coefficient. The purpose is to regulate the radiation coefficient of household direct-acting room heaters.

Numerical measurement methods.

---Part 3: Additional Regulations for Radiation Efficiency Measurement. The purpose is to regulate the radiation efficiency of household direct-acting room heaters.

Rate measurement methods.

Household direct-acting room heater Performance Testing Methods Part 1: General Requirements

1 Scope

This document describes the performance testing methods for household direct-acting room electric heaters (hereinafter referred to as "heaters").

This document applies to portable, stationary, fixed-mount, and recessed heaters.

This document does not apply to.

---Storage room heater (IEC 60531);

---Heats installed within the building structure;

---Central heating system;

---Wallpaper, blankets, or curtains equipped with flexible electric heating elements.

This document describes the basic characteristics of direct-acting room electric heaters and specifies the methods for testing these characteristics for user reference.

This document does not specify performance characteristic requirements.

Note. This document does not cover.

---Safety requirements (IEC 60335-2-30);

---Noise from fan-type heaters (IEC 60704-2-2).

3 Terms and Definitions

The following terms and definitions apply to this document.

direct-acting room heater when a room needs heat, it can convert electrical energy into heat energy and immediately deliver the heat energy to the appliances in the room.

plate heater

Note 1.Some plate heaters are equipped with an oil-filled structure.

Note 2.Some plate heaters include columnar structures.

convection heater

During normal use, at least one unseen part of the heater that comes into contact with the room's circulating air experiences a temperature rise exceeding 75K.

Natural convection is used to discharge air from one or more outlets.

Note. "Invisible parts" refers to parts that are not visible from 2m in front of the heater and 1.2m above the ground after the heater is installed.
