wholesaler,you,how,check,your, technology As a wholesaler,do you how to check your faucets quality?
The electronic cigarette is not new. People who buy electronic cigarette knows that this product has been in the market for years now. Despite some sectors apparently trying to shoot the product down from the shelves, the popularity of elect Active shredder safety technology for the small office.

Perhaps,many wholesalers don't check their faucet products quality by themself,just ask their suppliers to do these,if problem comes,you may need to return to your faucet supplier,and change new some,that will lost your time,why not check the products before you received it?Like faucets,there are many things you should know about.(of course,you can't check it just at home,because it need some special test equipments).Maybe the next checking list is boring,but that is what we have to do before shipment,to ensure each of our products is in good quality.(PS. Also you can set the QC standard to your supplier,that may be easier for you. :) )1.Appearance qualitySurface plating for the spaut should be in good combined treatment. Organizations should be meticulous and looks sharper and curves smoother.Polishing surface should be brightness and without bubble,burns,dislocation and scratch defect.2.Surface quality for screw-threadNo dent and thread breaking defect. Surface RA≤3.2um3.Pipe thread accuracyAccuracy should reach the GB/T7307-2001 standard4.Sign of cold and hot waterThe clear sign of cold and hot warer .Blue/C/cold means cold water ,Red/H/hot means hot water .Double spout,cold water sign at right side, hot water sign at left side .The connection is firm. 5.Flow Rate(L/S)Under the (0.3±0.02) Mpa water pressure , the folw rate not less than0.2 L/S.Under the (0.1±0.01) Mpa water pressure , the folw rate not less than0.15 L/S6.Sealing performance Connector:1.6±0.05Mpa water pressure after60±6s no leakageCartridge:1.6±0.05Mpa water pressure ,after60±5s no leakage0.05±0.01MPa water pressure, after60±5s no leakagewater partition:0.4Mpa±0.02Mpa water pressure after 60s±5s no leakageSealing:0.4Mpa±0.02Mpa water pressure after 60s±5s no leakage7.Packing requirement After assembling,the handle must be smooth,light and without resistance.The connecting with handle and the valve rod should be tight. The torque of single handle should be over 6Nm±0.6Nm;The torque of cold and hot water button should be over 2.5Nm±0.5N. After testing,all of the parts shouldn't be out of shape;the cartridge should be seal and the flow rate should be approved the requirement standard.8.Adhesive Force Ater the adhesive force testing,chrome finished not allow fall out.9.Intensity of valvesinflow part:2.5±0.05Mpa water pressure, after 60±5s, no deformation, no leakageeffluent part:0.4±0.02Mpa water pressure, after 60±5s, no leakage10.casting qualitywithout defects such as shrinkage, cracks and pores, inner cavity with the core sand should be cleared away.11.Ceramic piece hardware:≥1000Hv512.coating, corrosion performanceAccording to GB/T10125,after 24 hours acid salt spray test, should reach 10 level standard of GB/T6461-1986 requirement 13.Fatigue test of Cold and hot functionConnector:1.6±0.05Mpa water pressure after60±6s no leakageCartridge:1.6±0.05Mpa water pressure ,after60±5s no leakage0.05±0.01MPa water pressure, after60±5s no leakagewater partition:0.4Mpa±0.02Mpa water pressure after 60s±5s no leakageSealing:0.4Mpa±0.02Mpa water pressure after 60s±5s no leakage14.Screw TorqueCan bear torque of 61Nm,no crack,no damage 15.PackageMaterial,logo,components bag meet the requirements 16.others.(Via. www.banyanfaucet.com)
