Thanks to everyone that responded to my query. Here is my original question and a synopsis of the replies.
Question: We currently design our products to comply with the Class B emissions limits of EN 55022, but I am getting a lot of pressure from engineering to allow the limits to be raised to Class A. The equipment is intended for business use only. I understand that Class A is legal in the EU for business equipment, and our customers don't seem to understand or care if the equipment is Class A or B. So, the question is this - Are you successful in marketing your business ITE as Class A? Replies: My business/commercial/industrial ITE clients have usually aimed for Class B but if they did not get there, Class A has always been accepted by their customers. Most customers do not know the difference & very few will insist on Class B (tending toward laoratories and such locations where small signals are involved, and interference would be likely). Class A business ITE is the norm from my perspective. I see very few products of this category subjected to the more severe Class B limits. I surveyed our customers and changed from Class B to Class A a few years ago, and have had no issues. We are an OEM provider and have not had any issues marketing and selling class A products. We have found that the requirement of being "Class B Certified" was a perception of our marketing department and was not consistent with our customer's requirements or needs. As such, we have found it viable and feasable to move Class A ITE product to customers in all parts of the world without issue. We have sold class A video products (intended for business use only) via distributors for the whole life of the EMC Directive and have never been questioned. There are many business products that are labeled or otherwise identified as "Class A" when used in a commercial environment and "Class B" when used in a residential environment. Although it can be argued that my products are Class A, we design our products to meet Class B. I have had the occassion where I was at the limit and was under pressure to release the product that I have taken Class A. Primarily we've designed for Class B as a 'specmanship'game with the competitors who mostly have Class A. Thanks again to all who replied.
