I just noticed that the ASTM E1264 for ceiling panels has been updated, as of 2023. All the classifications for Types and Forms are different.

I checked the IBC code to see if this ASTM was referenced in the code, and it is NOT. This would mean that the latest version of the ASTM would be applicable on projects, unless you are specifically calling out the year for this ASTM.

All ceiling panel products now have new classifications to meet the new ASTM, and so y'all should check your product listings to be sure they're up to date. On the USG product data sheet I happened to be looking at, they list both the old classifications for ASTM E1264-22 and the new ones for ASTM E1264-23.

Hi Rosa. Until the big players adopt it, my understanding is that this new standard cannot be enforced since no one can meet it. No point in specifying around something that does not yet exist.

My understanding is that the only significant change to the standard is how the products are now designated, and not that current products no longer meet the standard.

If that is true, it is simply a matter of manufacturer's updating their product data, and not an issue with testing and modifying specific products.

Agree with Ron. The panels themselves are not changing...just the classification.

Where this really comes into play is that there are actual classifications now for some of the ceiling panels that previously fell under Type XX (the old catch-all classification) - such as acoustical wood panel ceilings, vinyl-faced panels, etc. They also now have separate classifications for metal pan ceilings versus metal plank ceilings.

USG listed both old and new classifications on the product data I saw, giving the year of the ASTM E1264 standard that each classification falls under. A quick look at Armstrong shows they only have the old ASTM classifications listed, and don't clarify that this is the old ASTM E1264.

My point is that if you have something in Division 01 that says all standards are "latest versions" unless otherwise indicated, then you will have a conflict when you call out old classifications. And if you call out the new classifications, then the product data that is reviewed during construction may not match the latest classifications.
So...Will you add a year to the standard you list in the spec? Will you choose to list both classifications? Will you eliminate classifications altogether and just list product names? Will you do nothing and let the folks doing CA deal with it?
How each spec writer wants to resolve this issue is not my concern...I was just pointing out the issue.
