Escopo e aplicabilidade

This standard applies to ceramic cartridge faucets installed at the terminal ends of cold and hot water supply pipelines within buildings. It is specifically designed for systems with a working pressure (static pressure) not greater than 1.0 MPa and a medium temperature ranging from 4°C to 90°C. Manufacturers of washbasin, kitchen, shower, and bathtub faucets must comply with these regulations to enter the Chinese market. It does not apply to faucets operating outside these pressure and temperature parameters.

Requisitos técnicos

The standard specifies comprehensive technical requirements, including mandatory clauses for metal pollutant extraction and specific usage performances. For washbasin and kitchen faucets, the lead extraction statistical value (Q) must not exceed 5μg/L, with strict limits on 16 other non-lead elements. Compliance with these hygienic limits is strictly enforced for drinking water safety. Regarding hydraulic performance, the standard categorizes flow rates into standard and water-saving types, specifying exact flow limits depending on the faucet's application (e.g.,普通洗涤, kitchen, shower). It also introduces a sensitivity requirement for single-handle dual-control faucets to ensure precise temperature regulation. For mechanical durability and structural integrity, the standard outlines requirements for anti-hydraulic pressure performance, sealing performance under various pressures, and anti-load capabilities. Faucets must withstand specific installation torques and axial pulling forces without deformation. Additionally, surface corrosion resistance and coating adhesion strength are rigorously defined to ensure product longevity.

Métodos de ensaio

The standard outlines various testing methodologies to verify compliance. Key tests include the metal pollutant extraction test (detailed in Appendix B), which involves a 19-day immersion process in a simulated tap water solution. Hydraulic performance is evaluated using a specialized test rig (Appendix C) to measure flow rates and sensitivity. Manufacturers must also conduct lifecycle tests for switches, diverter valves, and pull-out hoses to ensure long-term reliability. Furthermore, acidic salt spray tests are mandated to evaluate surface corrosion resistance, alongside thermal shock and cross-cut tests for coating adhesion.

Perguntas frequentes

What products are regulated under GB 18145-2014?

GB 18145-2014 applies to ceramic cartridge faucets installed in buildings with a working pressure ≤1.0MPa and a medium temperature of 4°C~90°C. It covers various types including washbasin, kitchen, and shower faucets.

What are the main updates from the previous GB 18145-2003 version?

The 2014 version introduced mandatory requirements for metal pollutant extraction (including lead limits), added anti-siphon performance criteria, and updated the medium temperature range from ≤90°C to 4°C~90°C.

Does GB 18145-2014 align with international ISO standards?

Yes, the standard references several ISO standards for testing methods, such as ISO 2859-1 for sampling procedures and ISO 9227 for salt spray tests, adapted specifically for Chinese market compliance.
