Specifies the volume and file structure of diskettes for the interchange of information between users of information processing systems. It also specifies an optional record structure. It is identical with, and has been reproduced from, ISO 9293:1987.

This Standard sets out the method for determining the permittivity of geotextiles by measuring the flow of water through the fabric normal to its surface under a constant head.*
