コンプライアンス概要
この概要は現在英語のみで提供しています。
適用範囲
This standard applies specifically to pressure switches used in automatic sprinkler systems. It is not applicable to pressure switches used in gas fire extinguishing systems or explosion-proof pressure switches used in flammable and explosive hazardous environments. Engineers designing or certifying fire suppression components for the Chinese market must verify compliance with this standard.
技術要求
The standard mandates that the rated working pressure of the pressure switch shall not be lower than 1.2 MPa. It defines specific action pressure ranges for different types of switches, such as ordinary and pre-action devices. Manufacturers must ensure their products actuate strictly within these defined pressure limits to guarantee system reliability. Physical and structural integrity requirements are comprehensive, covering strength testing under 1.5 times the rated working pressure without damage or leakage. The standard also sets strict criteria for contact resistance, mandating that it shall not exceed 0.1Ω under normal atmospheric conditions. Devices must feature at least one pair of normally open and normally closed contacts to be compliant. Environmental durability is a core focus, specifying performance criteria for damp heat resistance, vibration, and collision. The device must not misfire during these physical stress tests. Furthermore, it includes stringent corrosion resistance requirements, specifically evaluating the device against both salt spray and sulfur dioxide (SO2) environments, referencing test methodologies adapted for harsh industrial conditions. Electrical safety is addressed through insulation resistance and dielectric strength requirements. The device must withstand specific AC voltage levels for 60 seconds without surface arcing, corona, or breakdown. All mandatory chapters regarding model compilation, requirements, and inspection rules must be strictly followed for product certification.
試験方法
The standard outlines several critical testing procedures, including the Action Test, which verifies the actuation pressure and contact reliability. The Strength Test evaluates structural integrity under hydrostatic pressure. Work reliability tests are conducted across varying temperatures to simulate real-world operational cycles. Additionally, it specifies procedures for Salt Spray and SO2 Corrosion Tests, Vibration and Collision Tests, as well as Insulation and Withstand Voltage Tests, referencing GB/T 191 for packaging evaluation.
よくある質問
What products are regulated under GB 5135.10-2006?
This standard applies specifically to pressure switches used in automatic sprinkler systems. It does not apply to pressure switches used in gas fire extinguishing systems or explosion-proof pressure switches used in flammable and explosive hazardous environments.
Are there any updates from the previous version of GB 5135.10-2006?
Compared to the previous GA 29-1992, this standard unifies the model compilation for pressure switches, provides more detailed regulations on action pressure values, and adds a sulfur dioxide (SO2) corrosion test. It also includes specific requirements for marking and connection methods.
What are the specific pressure requirements for pressure switches under this standard?
The standard specifies that the rated working pressure of the pressure switch shall not be lower than 1.2 MPa. The action pressure varies by type: for ordinary types, it is 0.035 MPa to 0.05 MPa, and for pre-action devices, it is 0.03 MPa to 0.05 MPa. Manufacturers must ensure their products meet these specific pressure thresholds.
The summary above provides a high-level overview of GB 5135.10-2006.
