ISO 15223-1 has about 44 symbols in it. IEC/TR 60878 has over 500 in it. Many
of the symbols in 15223-1 are in the 60878 but not all. However, the good news
is that 60878 is being revised and the 3rd Ed should be published soon and will
have all the symbols from 15223-1 in it (and over 800
The way I would apply it would be first to apply any specific safety messages
that the end product standard states. If you need a safety message that is not
defined by the end product standard, than the signal word you choose should
follow their definitions and matched up with your risk
I heard that the MDD HS list may get updated in November. Not sure about the
others. If anyone has any details, on how the timing of the HS list updates
occur, please provide the details.

Hi,
The data must be able to be displayed in SI units but it does not prohibit the
equipment to display other units of measure. At least that is my understanding
of this requirement.

Gary, not sure you are going to find anything more clear than what is

implementation dates that I am aware of:

this date. Does not apply to existing

testing of UL 94, let me know which interpretations you believe are
correct. I have heard arguments for both.

As you are probably aware, there are no exact equivalencies between IP
NEMA/UL Type ratings since they are based on different standards/tests. The
only standard that I am aware of that provides a general comparison guide
between the two is the 2003 version of NFPA 79 (Table F.5.5).

Hello all,
In IEC/EN 60204-1 (safety of machinery), one of the conditions required to
meet a PELV circuit is:

other live circuits. Electrical separation shall be not less than that

According to Table 46.1 of UL 508, the minimum amount of cycles the

Ultimately you should contact the manufacturer to find out how many cycles

Chris,
The requirements given in NEMA 250 versus UL 50 are virtually the same
(although both are different than IEC 60529). The definitions and test
requirements are very similar for all types (1, 2, 3, 3R, 3S, 4, 4X, 5, 6,
6P, 12, 12K, 13). The big difference comes in the process of using the
