Same harmonised standards

Similar risk profile

## FAQs

### When can I use a family declaration?

When variants are functionally identical in compliance-relevant aspects. Cosmetic differences qualify. Different power ratings or radio modules require separate assessment.

### Do I need to test every variant?

Not if covered by family declaration. Test representative variants. Document rationale for coverage. Significant differences require separate testing.

### How do I document variants?

Create master technical file with variant matrix. List each variant, identification, and differences. Document rationale for family coverage.

### Can color differences be in same family?

Yes. Color and cosmetic variations don't affect compliance and can be covered under family declaration if they don't impact safety or EMC.
