Class Information
Number: 428/613
Name: Stock material or miscellaneous articles > All metal or with adjacent metals > Porous (e.g., foamed, spongy, cracked, etc.)
Description: Subject matter comprising at least in part, a nonfibrous, nonparticulate material which contains tiny openings, often microscopic, through which certain fluids may pass. Generally the pore opening is of such irregular direction and small dimension that light will not pass through the porous component without distortion or diffusion.
