Hello all,
I believe that the value of Durability of marking is very high. You don't
want to test the product using wrong type of solvent / chemical. Based on
UL / IEC 60601 , 2nd or 3rd edition (medical standard) or UL/ IEC 61010-1
2nd or 3 edition (Control and Laboratory equipment ) , UL 60950, 2nd
edition, all required different ways of testing Durability of marking test
for your safe label into your product.You don't want your product label to
be damaged easily once you released the product in the market.Even if you
have the great product, it does not look good if you cann't see the label
easily. So, for these reason the value of your product label is very high
for any product you made. For my product, i wanted to use right chemical
per UL/IEC standard suggested even if cost is high at front.
I had done many Durability of marking test but most of them failed using
either Isopropyl alcohol or n- Hexane after rubbing for certain time
required by the standard , some of the test i have seen ink damaged
completely just by wet (using water ) cotton rubbing into label or some
product's label come off easily because of applied chemical solution to
the product ( marking not even visible after the test). So, you wanted to
use right material with right type of ink on your product's label to pass
the test successfully.
I think the following 49 countries are members the CB Scheme, correct me
if i am wrong.
Argentina, Australia, Austria, Belarus, Belgium, Brazil, Canada, China,
Croatia, Czech Republic, Denmark, France, Finland, Germany, Greece,
Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Kenya, Korea,
Malaysia, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal,
Romania, Russian Federation, Serbia, Singapore, Slovakia, Slovenia, South
Africa, Spain, Sweden, Switzerland, Thailand, Turkey, Ukraine, United Arab
Emirates, United Kingdom, Uruguay and USA
Product safety and its importance for all people and industries "Consumer
product incidents cost the nation more than $900 billion annually"
According to Consumer product safety commission "CPSC is charged
with protecting the public from unreasonable risks of injury or death
associated with the use of the thousands of consumer products under the
agency's jurisdiction. Deaths, injuries and property damage from
consumer product incidents cost the nation more than $900
billion annually. CPSC is committed to protecting consumers and families
from products that pose a fire, electrical, chemical or mechanical hazard.
CPSC's work to ensure the safety of consumer products - such as
toys, cribs, power tools, cigarette lighters and household
chemicals - contributed to a decline in the rate of deaths and injuries
associated with consumer products over the past 30 years.Federal law
bars any person from selling products subject to a publicly-announced
voluntary recall by a manufacturer or a mandatory recall ordered by the
Commission."

Subject: Re: [PSES] 60950-1 durability test solvent
David et al,
Lot's of discussion around a topic that is hardly
mainstream in most
product certifications.
The frustrating part is that the 950 committee intended
to implement
a simple test that had successfully been used for many years, I remember
the
discussion. However it was clear from the outset that the use of a
generic
product class name (mineral spirits) was not acceptable on a worldwide
basis
so it was converted to a chemical naming. This, however, has caused
ongoing
headaches, as you have noted, in procuring and using the material in
product
evaluation. Worse yet if you has to have a chemical composition test data
from the supplier from a calibrated machine.
Complication, obfuscation and despair... How can
something so
simple be made so complicated.
Oh well, that's what you get your ulcer money for.
