You can have VOC testing done to determine if yours are off-gassing. That's the real test, not the FDA. Generally speaking Luxury Vinyl Planks are the way to go if you don't want to risk off-gassing.
A simple TVOC & HCHO meter at home should imho be a low-cost first step, indicating a need for improved ventilation, or for eliminating questionable sources of the gassing. The alcohol hand sanitizer sets off the TVOC reading though.
I’m not convinced that the TVOC sensor included on consumer air quality monitors does much beyond give people anxiety. Maybe it’s useful if it prompts people to open their windows more often, but mine is so impacted by daily activity and subject to calibration drift to the point I wish it wasn’t part of my sensor unit. Opening a single bottle of beer will spike the levels for hours. It’s a super effective fart detector. I’ve had one for four years but I don’t know how I’d use it to determine whether some new product was harming the air in my home, the readings are just too noisy.
Luxury Vinyl Plank (LVP) flooring is made up of multiple layers of materials, including polyvinyl chloride (PVC), wood composites, and limestone stabilizers:
Backing: A layer of foam, cork, or PVC
Core: A WPC (wood polymer core) or SPC (stone polymer core) core
Vinyl layer: A layer of PVC
Glass fiber: A layer of glass fiber
Print layer: A layer that displays the product's colors and design
Wear layer: A protective layer made of polyurethane that resists scratches and stains
Hm, I wonder how that composition varies, but at least off-hand the quantity probably matters. It's the off-gassing and the top coat that get you with flooring.
