Peter,
I have some documents on these but they are in hard copy format. Give me
your fax/phone number and I will get them to you.
Thanks

Hi Guys,
Does anyone know what a typical conductivity or resistivity is for
yellow zinc coating???

Are we talking ohms or ohms per square?
If it's ohms per square, .3 or .4 seems a little high
for a metal sheet. Depending upon alot of factors,
I'm used to Cu conductive coating on plastic running
roughly just a little less than this and Ni conductive
coating on plastic running just under
Homi Hi!
I geatly appreciate your help. My fax # is 972-3-5339019. My

Don't have the figures to hand but having checked it out a while ago we
have moved from the gold/yellow zinc passivation on steel parts to the
silver/clear finish:
UK spec: BRIGHT ZINC PLATE TO BS 1706 Fe/Zn 8 c 1A
US spec: BRIGHT ZINC, ASTM B633, TYPE III, Fe/Zn 8
This has a much lower
Hello group,
which supply voltage is used according to the C-Tick regulations?
We are selling information technology equipment in Europe and to the United
States. Because of the FCC regulations some tests are done at 110V.
Is there any regulation regarding to the amount of Volt in Australia?
I will second what Chris says. The yellow zinc has a surface resistance
that must be penetrated in order to have conduction across joints.

You have to look to the standards for the answer. Since the Australian
standards follow CISPR, the standards require that you test at the nominal
voltage and frequency of the country. Australia's power system is 240V 50 Hz
(some areas in the outback can reach as high as 250V nominal). A retest of
I will also second that.
We have turned away from using yellow zinc coating, as well. We found that the
yellow zinc coating was prone to early oxidation which had a purple color.
This
oxidation was evident on most surfaces, but was most prevalent at the joining
surfaces (Murphy's Law).
Hi Doug,
You are right. Thanks for the correction. The unit to describe the surface
conductivity should be ohm per square. Actually, I use Conductivity Prob,
purchased from SPRAYLAT, to check surface conductivity. --Barry.

Sometimes this gets confused with yellow-chromate and is usually
anodized onto the metal. Its great for incoming inspection because they
can see it clearly, but not so great for conductivity. The bright zinc
seems to satisfy everybody, they can inspect it and we seem to be
getting good

I'm not familiar with the Galvanel surface treatment, but if it is some type of
zinc coating on the steel, welding is a bad technique. I understand that the
heat of welding vaporizes the zinc, resulting in hazardous vapors in the work
area. Secondly, the zinc tends to contaminate the
