Flow rate test

According to the (GB18145-2003), dynamic pressure under 0.3, without any condition, flow rate of bathtub should be ≥0.33 L/S; basin should be ≥0.20L/S. (Detail specification of products, please refer to the below table) Flow rate change under different pressure:

Pressure (Bar)	0.5	1	1.5	2	2.5	3	3.5	4
Average flow rate(L/min)	12.2	14.5	16.9	19.8	22	24.2	25.8	27.4

Burst test pressure

Sealing test

Test Item	Outlet status	pressure (MPa)	time(s)	Technical Requirements(according to GB18145-2003)	Test Conclusion
Inlet	Open	1.6±0.05	60±5	No leakage	Qualified
		0.4±0.02
Outlet	Close	1.6±0.05	60±5	No leakage	Qualified
		0.4±0.02

Cold /Hot water cycle test:

Put cartridge into -20±2°C and 95±2°C environment in turn. Every 12 hours as a period, do three times cold and hot water test continually; after that, put cartridge into 80±5°C water and mild water in turn in every 40 seconds, do 450 cycles continually. No leakage after cold/hot water cycle testing.

Life cycle testing:

According to the EN817,GB18145-2003 standard test more than 70,000 cycles (hot water temperature: 65±2o,cold water temperature: ≤30o,pressure: 0.3±0.05Mpa); According to the ASME A112.18.1-2005 standard test more than 500,000 cycles (hot water temperature: 66±6o,cold water temperature: 10±6o,pressure: 0.3±0.05Mpa). Technical data(according to ASME A112.18.1-2005) as the following table.
