NEMA seems to be saying PVC cement is a generic product regulated by ASTM D 2564.

Selection of Solvent Cement
Solvent cements intended for use with PVC conduit and duct should meet all
the applicable requirements of ASTM D 2564, “Solvent Cements for Poly(Vinyl
Chloride) (PVC) Plastic Piping Systems.” Since they are available in a wide
range of viscosities and wet film thicknesses, the nature of the particular project
must be considered when trying to decide between a regular, medium, or
heavy-bodied cement.
