When do I test?

If you are required to test, you will do so on the prototype that you will send out to your customers.

If you make a change in your prototype, retest. Color does not constitute a physical change for physical tests, but shape and size can.

How often do I test?

You will need to test yearly. If you are using a supplier's testing reports for a component, request a new document if it is more than 1 year old.

Are there exemptions?

Yes, you can find some exemptions for Total Lead Content and Flammability of Wearing Apparel testings in the image from my book series below.

You can find more exemptions in Chapter 16 of the Code of Federal Regulations (eCFR.gov).
