Escopo e aplicabilidade

This standard specifies the patterns and basic parameters for fire insertion-type couplings. It applies to fire water supply systems, specifically covering hose couplings, pipe thread couplings, blank caps, and reducing couplings. This standard is mandatory for manufacturers producing these specific fire coupling components. It references GB/T 1804-2000 for general tolerances.

Requisitos técnicos

The standard defines the structural patterns and specifications for various insertion-type fire couplings, including hose couplings (KDK), blank caps (KMK), female pipe thread couplings (KYK), male pipe thread couplings (KYKA), and reducing couplings (KJK). It categorizes these components by nominal diameters and nominal pressures. Chapter 4 and Chapter 5 contain the mandatory provisions of this standard. Manufacturers must strictly adhere to the structural designs and basic dimensions outlined in these sections. The standard specifies dimensional tolerances and mating requirements for different coupling types. Additionally, the standard defines a specific marking method to identify the coupling type, nominal diameter, and nominal pressure. Unspecified linear and angular tolerances must comply with the rough class c requirements as specified in the referenced general tolerance standard.

Métodos de ensaio

While this specific part of the standard primarily focuses on patterns and basic parameters rather than testing procedures, compliance is evaluated through dimensional inspection and structural verification. Manufacturers must ensure that all basic dimensions and their deviations meet the specified tabular limits. The evaluation also includes verifying the correct application of the marking method and ensuring compatibility with applicable media such as water and foam mixtures.
