Information and documentation — International standard music number (ISMN)
ISO 10957:2009 specifies the International standard music number (ISMN), which is a means of uniquely identifying editions of notated music. It specifies the assignment of a unique ISMN on such editions so as to distinguish one edition of a title or one separate component of an edition from all other editions. ISO 10957:2009 also specifies the construction of an ISMN and its location on editions…
Aerospace — Omega clamps (saddle clamps) for fluid systems — Dimensions
This document specifies maximum and minimum dimensions for omega clamps (saddle clamps) installed by means of two bolts with nominal diameters of 5 mm.
The specified dimensions define a dimensional envelope. This document is not an interchangeability standard. The tolerances for each type of clamp are defined in the drawings in the standards for parts.
