This chapter of GB 4706.1 is replaced by the following content: this section covers the safety of various electric heaters used for animal breeding and breeding, such as heat radiators, chicken heating boxes, incubators, chicken feeding devices, and animal heating boards. For single-phase electric heaters, their rated voltage should not exceed 250 V; For other electric heaters, their rated voltage should not exceed 480 V. Note 101: This section applies to electric heaters equipped with electric motors intended for poultry breeding and breeding. Note 102: It should be noted that additional requirements need to be added for appliances used on vehicles, ships, or aircraft—— In many countries, additional requirements are stipulated by the national public health department, national labor protection department, national water supply department, and related departments. Note 103: This section does not apply to: - appliances specifically designed for industrial use—— Instruments intended for use in areas with special environments, such as corrosive or explosive gases (dust, steam, or gas)—— Heating device embedded in the floor—— Flexible plate heating element for room heating (1EC60335-2-96); - Indoor heaters [IEC 60335-2-30 (GB 4706.23)]. This chapter of normative reference document GB4706.1 applies except for the following content. Add: GB/T 2423.17-1993 Basic Environmental Testing Procedures for Electrical and Electronic Products - Test Ka: Salt Spray Test Method (eqv IEC60068-2-11:1981) GB 17936 Bayonet Lamp Holder (idt 1EC 61184) -3 Definition GB4706.1. This chapter applies except for the following content. 3.1.9 Substitution: Normal operation: The appliance operates normally in still air and in its normal state of use. 3.101 Heat radiating appliance is an electric heater that primarily transmits effective heat through radiation. Note: For this type of appliance, if the temperature rise measured at the hottest point of its radiator under normal working conditions does not exceed 95 K, it is considered an animal heating plate rather than a heat exchanger
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
