what is NSF 61-9 faucet?
As
everyone knows,maybe,north America(mainly for USA and Canada) certification Including,
but not limited to:
USA:
UPC, CUPC, NSF, WaterSense, AB1953, WQA
Canada:
CUPC, CNSF, CSA, SA, ASME
Do
anyone knows what is the faucet with nsf 61-9 certificate?Let me tell some
about it:
Lead
is the microelement which human being needs,but when the lead lead content is overweight,
it will become a "invisible killer" which damage our body health. So for
people's health,in some advanced country,like United States... there is a very
strict standard of lead content for pipes and faucets,and the standard is the
NSF 61-9 test.So the NSF 61-9 faucet mean the faucet which is low lead.According
to the dring water system compent of health effects under ANSI/NSF 61-9,to
analyse the lead content of the products,The ANSI/NSF 61-9 including the final
filter for the Installation and distribution system,the plumbing installation, components
and materials for tap water,like remote chillers,bathroom faucets.kitchen faucet
and so on.All in all,control the lead content of the faucet material.
Now many faucets are make of brass, but the
faucets which exported to North America mostly are make of DR brass(low lead
brass),and passed the UPC/cUPC certification, there are different standard or
certification in other countries or regions to make sure the faucet or other
products had pass the quality authentication. Nowadays,the brass processing
techniques is very mature, don't worry too much about the problem of lead
poisoning.Perhaps many people will ask, why not use stainless steel faucets, there
is no lead in stainless steel.One of the reasons is, stainless steel is high
hardness, it is relatively difficult in processing, there are other reasons, we
will talk in detail later. Of course, there are still lots of people using
stainless steel faucet, for example, in Europe,many people are using the
stainless steel faucet,and in Canada,gradually popularized the stainless steel
faucet.
