適用範囲
GB 5135.13-2006 applies to drencher nozzles (water curtain nozzles) used in automatic sprinkler systems for fire protection. It covers nozzles designed for fire separation and protection cooling purposes. This standard is mandatory for manufacturers producing water curtain nozzles for the Chinese market.
技術要求
The standard specifies comprehensive requirements for drencher nozzles, focusing on performance and durability. Key areas include flow characteristics, where the flow coefficient must remain within strict tolerances under varying pressures. The standard also regulates the water curtain spray angle and deflection angle, ensuring the spray pattern meets design specifications. Additionally, it mandates requirements for spray uniformity and the ability to block radiant heat, critical for fire separation effectiveness. Manufacturers must ensure their nozzles meet these performance criteria to achieve compliance. Environmental durability is also addressed, with requirements for ammonia stress corrosion resistance, sulfur dioxide corrosion resistance, and salt spray corrosion resistance. The nozzles must withstand low temperatures (-30°C) and high temperatures (800°C) without deformation or damage.
試験方法
GB 5135.13-2006 outlines several key testing methods to verify compliance: Flow Coefficient Measurement (testing flow rate vs. pressure), Spray Angle Measurement (photographic measurement of spray and deflection angles), Spray Pattern Test (mapping the spray shape at various pressures), Water Distribution Uniformity Test (measuring water volume in collection boxes), and Radiant Heat Blocking Test (measuring thermal insulation efficiency). These tests ensure the nozzle performs reliably under fire conditions. Corrosion resistance is evaluated through Ammonia Stress Corrosion, Sulfur Dioxide Corrosion, and Salt Spray Corrosion tests, while Low Temperature and High Temperature tests assess environmental durability.
よくある質問
What products are regulated under GB 5135.13-2006?
This standard regulates drencher nozzles (water curtain nozzles) used in automatic sprinkler systems. It specifically covers nozzles designed for fire separation and protection cooling purposes.
How are drencher nozzles classified under this standard?
The standard classifies nozzles into gap-type and impact-type based on structure, and into fire separation (G-type), protection cooling (L-type), and universal (T-type) based on usage. Universal nozzles must meet the requirements for both fire separation and protection cooling.
Are there any mandatory chapters in GB 5135.13-2006?
Yes, Chapter 6 (Requirements) and Chapter 8 (Inspection Rules) are mandatory, while the remaining chapters are recommended. Manufacturers must comply with the technical requirements and inspection rules to legally sell these products in China.
