When tested with an XRF instrument the silver-colored Kwikset door handle pictured here had the following readings:
- Lead (Pb): non-detect
- Cadmium (Cd): non-detect
- Mercury (Hg): non-detect
- Barium (Ba): non-detect
- Chromium (Cr): non-detect
- Antimony (Sb): non-detect
- Selenium (Se): non-detect
- Zinc (zn): 115,600 +/- 2,200 ppm
All testing is done with a freshly calibrated XRF instrument. Test results are science-based and replicable. Testing was done for a minimum of 60 seconds each time (with multiple tests done to confirm the results.)

As always, thank you for reading and for sharing my posts.
Please let me know if you have any questions.
It would help greatly if there was a model number, as manufacturers tend to make many variants. They all look the same in a blog article but a product name/number makes it possible not to confuse the few good from the many bad.
Hi Mark, I don’t have that information for this piece. I did not see any markings on it anywhere. I can ask the owner if she has any additional information.
Here’s how the testing gI report on this blog works: https://tamararubin.com/2017/07/subscribe-in-support-of-my-advocacy-work-you-can-become-eligible-to-send-in-a-box-of-your-things-for-testing/
Unfortunately I only have the information provided by the owners of the piece (especially when they are not sent in with any original packaging.)
Thank you for commenting.
It looks like the “Tustin” lever door handle in “satin chrome” from the Kwikset website.
