Textiles — Woven fabrics — Construction — Methods of analysis — Part 2: Determination of number of t...
Three methods of determining the number of threads per centimetre are included, any of which may be used, the choice depending on the character of the fabric. The principles are as follows: Method A: A section of fabric of dimension specified is dissected and the number of threads counted. The treads that are to be counted are preferably short, 1 or 2 cm being suitable. Method B: the number of…
This part defines the measuring principles to be used for measuring piston rings. Applies to piston rings up to and including 200 mm diameter for reciprocating internal combustion piston engines. May be used for piston rings for compressors working under analogous conditions. Several figures illustrate shapes and reference quantities of concern.
Dimensions of ball and socket couplings of string insulator units
Applies to string insulator units of the cap and pin and long rod types and their associated metal fittings for overhead lines. Includes six standard sizes designated by the nominal pin diameters which form the basis of the standard. Defines each standard size by the dimensions of the pin ball, of the socket and the hook-on 'Go' gauge. States dimensions of twin-balled pins for coupling…
