Sample evaluation
We were asked if we could evaluate the grit of an abrasive rotating disc, for an objective comparison of samples from different suppliers. The client’s goal was for the product from the new supplier to be very similar to that of the old supplier.

Sample comparison

The manufacturer sends us different samples at different stages, and those samples should all be very similar in the way they look, feel, and work. The samples might be:

• Commercial sample (before any order is issued)
• Pre-production sample
• During production sample
• Pre-shipment sample

A report with our findings.

Here’s an example of the checklist we follow (which is, of course, very dependent on the type of product):

And here’s the final report summary (which always includes photos):

Note that, in some cases, the samples will be disassembled and may not be fit for further usage.

We need to know your concerns and/or your objectives, and we will suggest an appropriate approach.

You can start by leaving a note with some of this info when you contact us for a quotation.

Yes, we can help you define a quality checklist, but we also ask you to provide us with your own requirements (about what’s important), how the products need to be packed and labelled, etc. This can vary from product to product. Guidance is provided if needed.

Please note, this is an extra service and will be charged separately – please ask us for details.

Yes, when you’ve selected a ‘winning’ sample and everything is agreed upon, we can ship it/them to you.
