Hi Kevin:

I agree with you that this is a poorly worded requirement.  However, it may 
help that this is not a mandatory requirement.  In TS 002, the word shall 
is used for mandatory requirements, and the word should is used to describe 
performance that is desirable, but not mandatory.  See clause 1.1 for the 
definitions of shall and should.

The word shall is used for the more specific fail-safe criteria in clause 
5.1.1.1.  These are somewhat easier to test for.

TS002 (Australian Telecom)

[Kevin Harris]

Hello Colleagues,

We just ran across a nifty piece of standards writing. In Australia in of
their telecom standards (TS002)  there is the following safety statement in
it. 

5.1.1.2 CE should not cause harm or damage to a Telecommunications Network
or Facility when CE is operated outside the range of operating voltage and
environmental conditions specified by the manufacturer

Our testing facility correctly has asked us to provide a DoC on this point
as it is un-testable but I have serious liability concerns about the
statement as it lets somebody hook up our device in any environmental
condition to any supply voltage and then when things go wrong point to the
DoC and claim they were justified in doing so. This standard is not new so
I'm sure many of you have come across this product safety issue before. Does
anyone know of some sort of interpretation guideline for this issue or
failing that, how have you solved this problem.

Thanks for your help
