Compliance overview
Scope and applicability
This standard applies to household and similar electrical appliances, specifically establishing noise limit values for products such as refrigerators, air conditioners, washing machines, microwave ovens, range hoods, and electric fans. It is applicable to manufacturers producing these appliances for the Chinese market. The standard does not apply to industrial or commercial equipment outside the scope of household use.
Technical requirements
GB 19606-2004 is a mandatory standard that sets strict acoustic limits for various home appliances. The core technical requirements are divided into specific product categories, defining maximum allowable sound power levels or sound pressure levels. For instance, it specifies distinct noise limits for direct-cooling and frost-free refrigerators based on their volume capacity. Similarly, air conditioners are regulated based on their rated cooling capacity, with separate limits for indoor and outdoor units, as well as split and integral types. Manufacturers must ensure that the measured noise values do not exceed the specified limits for their product category. For laundry appliances, the standard dictates specific A-weighted sound power levels for both the washing and spinning cycles of washing machines. Microwave ovens, including those with grilling functions, are subject to a uniform maximum noise limit. Range hoods are categorized by their air flow rate to determine the permissible noise level, while electric fans are regulated based on their specifications and types, such as table fans versus ceiling fans. All appliances must have their noise values clearly marked on the product's nameplate or instruction manual, with a strict tolerance: the measured value must not exceed the labeled value by more than +3dB, and must never surpass the standard's absolute limit.
Testing methods
The standard outlines the testing methodologies and acoustic environments required for compliance, primarily referencing GB/T 4214.1 for general requirements. Testing must be conducted in controlled environments, such as a semi-anechoic chamber, to ensure accurate background noise elimination. The standard specifies the operation and placement of the appliance under test, the positioning of microphones at defined measurement points, and the procedures for calculating both sound pressure levels and sound power levels. Specific testing conditions, such as rated voltage and normal load, must be strictly maintained during the evaluation.
FAQs
What products are regulated under GB 19606-2004?
The standard regulates the noise limits for various household appliances, specifically including refrigerators, air conditioners, washing machines, microwave ovens, range hoods, and electric fans.
Is compliance with GB 19606-2004 mandatory for market access in China?
Yes, all technical content in this standard is mandatory. Manufacturers must ensure their products meet the specified noise limits and properly label the noise values on the product's nameplate or manual.
How does GB 19606-2004 relate to international ISO or IEC standards?
The standard establishes specific noise limits based on Chinese appliance categories and references national testing standards like GB/T 4214.1. While it aligns with general acoustic testing principles, the specific decibel limits and categorization are tailored to the Chinese domestic market.
