Dear Jonathan,
Thank you very much for sharing.
I have a 3m chamber. What is your or members' comment I should request three
or ten meter calibration distance? My concern is: Section 5.1 of ANSI
C63.5-2006 (two paragraphs excerpted below for convenience) states "For either
use, the measur
Those systems are covered, but there’s nothing that excludes products. Take
for example an RCD device. Clearly its function is safety-related. Why
wouldn’t the 61508 series be relevant?

Hi Experts,
does anybody knows if Iraqi “civil” safety requirements exist
(Mandatory/non-mandatory? Is CB-scheme accepted? Approval required? CoC?)?

If a standard shall be listed under LVD, it must be electrical safety related.
I can’t see that 61508 should be LVD listed, since it deals with HW / SW
functional safety.
So you can sell a functional safety related product, CE mark it and not make
any references to LVD. An example is a flame det
Hello Grace, If it is a Lithium battery then it does require a (PS)E mark by
November 10th what type of battery do you have?

Dear Experts,
Can anyone please explain to me section 9.1.4.1 of NFPA 79? (see below)
NFPA 79
9.1.4 Connection of Control Circuit Devices.

indicator lamps (or transformer primary windings for indicator
lamps) shall be
Hi John,
Thank you very much. We have several different types of batteries. Lithium
battery is one of them. I believe the Japanese requirement starting November
20, 2008 is for the lithium battery.
I assume the PSE mark required is the diamond one (not circle one). Please
confirm.
Best re
Hello Grace,
You are correct in that Lithium Batteries are now regulated in Japan and
require the (PS)E circle mark not the E diamond mark.
Here is a summary of what I know
Japan's Ministry of Economy, Trade and Industry (METI) has added "Lithium
batteries:" into a list of regulated DEN
Hi Grace et al,
The Japanese battery requirement and the pertinent November 20, 2008
information originate from METI’s Electrical Appliance and Material Safety
Law and can be obtained at their website:

It's a little hard to comment w/o a schematic. But note that under NFPA 79
there are two classes of circuits. It seems like your heater circuit may be
considered a power circuit. Therefore, the inspector could be commenting on
the circuit which controls the "coil" of the 24V solid state relay.

61508 is not a product standard. It relates to systems that provide System
Safety where a portion of the system is electrical, electronic, or
programmable.
System Safety as a discipline looks at the severity of hazards that are
