Week 35 Quality Report & Added Feature



We have seen and heard of companies promoting themselves by claiming to have their parts tested at White Horse Laboratories prior to sale. While confirming product authenticity and functionality prior to sale or purchase is an excellent practice, it is fraudulent to make that claim falsely.

The frequency of this seems to be increasing, so we are now publishing those companies who promote a White Horse quality control program that does not exist. In most cases, we have not even heard of the company making that claim and/or using our name and logo without our authorization. We will also be publicizing and confirmed incidents of falsified reports.
