How are you guys planning to handle the new tip over rules from ASTM 2057-23? My furniture is pretty heavy already and we made some design changes to pass the old test, but with the addition of 10 more pounds to the test apparatus and the 7/16 spacer lifting up the back makes things very difficult. Rough estimations say I need about 50 lbs of ballast down low on the back of a 4 drawer bureau to be able to pass the simulated climb test. I'm just curious if anyone has found an elegant solution.

More rules, just what we need...

Jamie, I couldn’t find the parameters for the new rule, but having a pretty good understanding of leverage, it would seem using full extension drawer slides would require more ballast. So would it be possible to install some devise that would limit the distance that the drawer could extend?
Then maybe it could be eliminated by the parent after the child grows up. I don’t know if there are any slides that can be adjusted for the length of extension or not. However if not, I would be thinking about some sort of rocker latch that mounted inside the box, that had a tab passing through a hole, which hit a tab just inside the opening.
Maybe something as simple as a thumbscrew through the drawer side that hit the tab stopping the drawer at the shortened travel length.
Of course you would need an attorney to write the fine print protecting you if the parent chooses to not use the protective devise.

So to update everything, (and please understand this is all coming from a lay-man and not an attorney) The Conusmer product safety commission passed a rule in November that would have taken effect in May. Sand must have been raised over it by industry folks, because Congress passed the STURDY act just before the end of the year, supposedly nullifying CPSC's rules, but still making a much more strict and mandatory set of rules for Clothing Storage Units. They gave the CPSC some time to accept the new law in whole or in part, but there seems to be somewhat of a stalemate in place between the two, as CPSC's rule is still planned to go into effect in the end of May. Now having copies of both rules, the Sturdy act follows ASTM 2057-23, and is very understandable. Although the tests are hard to pass, it is very clear what you must do to pass. The CPSC rules are much more ambiguous and require stability ratings to be calculated and placed on packaging similar to the Energy Star labels we currently see on appliances. When I first asked this question, I wasn't aware of the CPSC sticking to their guns as it seems they are doing, so I thought it was just the ASTM tests, and was curious how people are getting by with hanging 60 lbs. on an extended drawer with the rest of the drawers open and it not tip over. Our furniture is very heavy, as its all solid wood, but very few of our pieces can currently pass the simulated child climbing test we easily passed before at 50 lbs. They also make you do the test with the back sitting on a 7/16" block to simulate carpet, which means the piece is already tilted forward when you hang the weight on it.
