I am proposing using the harmonized standards as guidance, not as an absolute 
determination. Article 1, Clause 2(k) gives specific exemptions including 
"household appliances intended for domestic use". How can you be sure your 
product is a household appliance reasonably covered by the LVD? If there is a 
harmonized standard under the LVD, then you at least have a good argument to 
make for declaring under the LVD. Without the narrow scope of the standard, you 
are left to argue the overly broad scope of the LVD versus the overly broad 
scope of the Machinery Directive.

I would also state that your simplest terms are a little too simple. There are 
plenty of electrical children's toys that could fit within your description. 
Lego Technic provides motors, transmissions, gears and other parts for a child 
to make something quite resembling a machine. The Machinery Directive does not 
exclude toys, but I have yet to see any of these toys declared under anything 
but the Toy Directive. The Machinery Directive does not exclude medical 
equipment, yet those products often have complex moving assemblies.

However, let me state that I am far from an expert in the Machinery Directive 
and I encourage all with contrary opinions to respond to set me straight. I am 
just another person trying to deal with the broad scopes and limited guidance 
available.

Subject: Re: Machinery Directive silly question?

I've said this before. The status of standard DOES NOT determine whether 
product is within the scope of a particular Directive or not.

To put it in its simplest terms, if a product has powered moving parts then, 
irrespective of the status or otherwise of any standards, it is within the 
scope of the Machinery Directive unless it is excluded by one of the clauses in 
Article 1. That's all there is to it.

Nick.

The first question I would ask is whether there is a product specific standard 
that covers your product. If so, then determine if that product specific 
standard is a harmonized standard under one of the other directives. In that 
case, the machinery directive would not apply.

For example, an air conditioner has plenty of moving parts. However, a small 
portable air conditioner intended to be installed and used by general users is 
covered by EN 60335-2-40, which is a harmonized standard under the Low Voltage 
Directive. This air conditioner would not fall under the Machinery Directive.

On the other hand, a large commercial air conditioner designed to be installed 
on the roof of a building is not within the scope of EN 60335-2-40. There are 
general standards covering the mechanical safety and the safety of the 
pressurized system, but not an overarching product standard for this type of 
product. As such, it falls under the Machinery Directive.

You may need to do some research to see if your product is within the scope of 
a product specific standard. However, if it is and if that standard is a 
harmonized standard under the Low Voltage Directive, the LVD would likely 
apply. These standards are designed to cover potential mechanical hazards 
specific to certain product types, but they are recognized as covering product 
where electrical hazards predominate.

This is not just the case for the LVD. There are medical products with moving 
parts and toys with moving parts and those are each covered under their own 
directives. If your product has a radio, and it is covered by a standard 
harmonized under the R&TTE Directive, that Directive may be the one that 
applies.

Subject: [PSES] Machinery Directive silly question?

Dear Colleagues,

I know that you are all patient with what might seem silly questions, so I hope 
you'll be patient with mine.

I have not had to consider the Machinery Directive before, but a new electrical 
product has a moving part in it.  It's a wholly enclosed (inaccessible in the 
middle of the equipment) fan that blows air through the equipment (not a 
cooling fan).

The MD defines machinery: " an assembly, fitted with or intended to be fitted 
with a drive system... consisting of... components, at least one of which 
moves, and which are joined together for a specific application".

So the silly question is, if the moving part is wholly contained within the 
equipment and is inaccessible, does the MD apply or do I apply the LVD?

I have Googled this question and have found references that say the MD does 
apply (it's the enclosure that makes the moving part safe), and references that 
say the MD does not apply (as the moving part is wholly internal, one doesn't 
need to even consider it).  I strongly suspect the former statement is the 
correct one.

Your authoritative opinions are sought!

With thanks in anticipation,

Mark
