IMPORTANT: Samples are typically provided to support engineers representing commercial entities (e.g. a corporation) for those entities’ product designs. We may also deliver samples to students (including students at universities and colleges) and educators to support their curriculums and projects (approved by their respective government-registered schools, colleges, or universities). Samples must not be resold. We generally accept sample requests from corporate (e.g., .com / .co.uk) accounts and educational email domains such as .edu or .ac, but in any event, provision of sample products or acceptance of any sample requests are subject to our terms and conditions relating to product samples.
