In compliance with the regulation of WEEE directive 2002/96/EC, some of our
european customers ask us for certifying prior regulation. Yet I know there
are a categories showing the equipment/appliance that should be covered by
this directive. Based on the directive, I am wondering the product manfactured by my company whether should be included. The business nature of my company is Liqual crystal display and Liqual crystal module OEM.
Thanks for your comment in advance.

It is the end use of the product that is covered by the RoHS directive. As LCDs are used in all sorts of applications it is quite likely that some of those will be covered by the directive. You may lose orders if you do not offer RoHS compliant parts.

Hi Keung830,

As told by spanner, you should be providing RoHS compliant LCD's to the customers.

For RoHS (Directive 2002/95/EC), you have to test atleast 3 batches of your product to check for the acceptance of the RoHS criteria for the 6 substances. You may also be needed to provide a declaration for fulfilment of RoHS criteria.

WEEE may not be applicable for you as it applies to end product.

Dear groupmate,

Yes, you are right. Therefore.my company has started the RoHS program. As you said, I think we don't need to care about WEEE as it is for end product. Yet, some of my customers still ask us for WEEE questions. They suppose that we should be involved into this program. sigh............. what should I do?:confused:

Thanks a lot !!! :D

Keung830,

The WEEE is basically for branded or finished products with the intent of Reuse, recycle or Recover.

I am attaching the directive (in case you do not have one). You can see clearly that its not for a component whilst refers to the finished product. You can talk to your customer and convince him for the following -

Refer Annex IA - this talks about the categories for WEEE

Refer Annex IB - this lists the products which should be taken into account for purpose of the WEEE Directive

Annex II - mentions the minium components to be removed from collected WEEE and this list contains your "LCD's" ;)

You can highlight him about Annex IV which mentions that all the products wich attract WEEE should be labelled with the "Bin logo"

I think with all these, your Customer should be convinced :)

Hi Keung,

Your LCDs are incorporated into larger machines/equipment that are covered under WEEE. Therefore, you cannot assume that you have nothing to do with WEEE.

At the minimum, I think you owe your customers the following 2 duties:
1. Disclose the contents/components and any hazardous substance present - together with relevant test results, CoA etc.
2. Depending on the size of LCD, to suggest procedures or methods of dismantling/disposal and perhaps the weight of each component.

I attach herewith an example (but this is for California and for lab use) for you reference. Having said that, its best to clarify with your customers what their exact requirements are.

Regards.

For RoHS (Directive 2002/95/EC), you have to test atleast 3 batches of your product to check for the acceptance of the RoHS criteria for the 6 substances.
Where can I find the requirement stated to test at least 3 batches?

Dear Groupmate,

Thanks for your comments again.

Actually, I think that we should do something for WEEE even supposing that the products are not covered.

I understood that LCD contains different kinds of chemical substances which are harmful for human-being in particularly liquid crystal. As a qualified quality engineer as me, I will propose to our boss doing something on it.:rolleyes:

Thanks!!:D

Hi Al,

I dont have any reference to testing three batches, but we follow based on the magical "3" which is adopted for Validation. By getting 3 sets of results, we can assure that the results are reproducible.
