Richard, et al;
The use of 'universal' markings continues to be controversial. In
order for markings to be universally accepted there needs to be considerable
training as to the correct interpretation as to what the symbol means. This
has been confirmed by several studies. Adding any symbol to a symbol
library (e.g. IEC 60417, for example) is not sufficient training to get
widespread recognition and understanding.
Since I'm one of the guys who has pushed the Triodyne article as a
point of view that shows that these symbols are not consistently used, I
support the article and would like to see less use of symbols alone until
there is a well trained, worldwide community of consumer users that
understand the significance of the symbols.
I favor combining symbols with language markings until this
understanding is established. I know that this is a frustration to
manufacturers but needs to be done.
I know of several innovative ways to do this; it is not impossible.
The use of local language markings is not negative when it comes to the
consumer or user. These folks feel that any manufacturer who goes to the
trouble to do such is really interested in their business.
As an alternative, perhaps this group would work on the use of a
universal, worldwide language (English, for instance) which would take care
of this problem.
Thanx to Rich N for pointing this out again.
