Specifies and describes a system for use in product standards; gives examples for hexagon head bolts, screws, and nuts, tapping screws, parallel pins, and washers.
Fasteners — General requirements for bolts, screws, studs and nuts
Requires that standardized products are defined by: mechanical properties (material), product grade (tolerances), surface coatings (if required), special requirements (if agreed); gives specifications and reference to International Standards.
Aéronautique et espace — Colliers à serrage central pour systèmes de fluides — Dimensions
La présente Norme internationale fixe les cotes maximales et minimales des colliers à serrage central fixés à l'aide d'une vis de diamètre nominal 5 mm. Les dimensions fixées définissent une enveloppe dimensionnelle. La présente Norme internationale ne doit pas être considérée comme une norme d'interchangeabilité. Les tolérances pour chaque type de collier sont à définir dans les…

La présente Norme internationale fixe les cotes maximales et minimales des colliers en oméga fixés à l'aide de deux vis de diamètre nominal 5 mm. Les dimensions fixées définissent une enveloppe dimensionnelle. La présente Norme internationale ne doit pas être considérée comme une norme d'interchangeabilité. Les tolérances pour chaque type de collier sont à définir dans les dessins de…
Specification of requirements for materials used for permanent abturation of the root canal with or without the aid of obturating points. This standard only covers materials intended for orthograde (root filling inserted from coronal aspect) use. Reference is made to ISO/TR 7405 for requirements that relate to the freedom from toxicity.
Aerospace — Omega clamps (saddle clamps) for fluid systems — Dimensions
Includes maximum and minimum dimensions for clamps installed by means of two bolts with nominal diameters of 5 mm. The specified dimensions define a dimensional envelope. Shall not be considered as an interchangeability standard. The tolerances for each type of clamp are to be defined in the parts standards drawings. These clamps are intended for the installation, support and guiding of rigid…
Cup head square neck bolts with large head — Product grade C
Specifies the characteristics of products with metric dimensions and thread sizes form M 5 up to and including M 20; tabulates thread sizes M 5 up to M 20 with nominal lengths from 20 mm up to200 mm and specifications with reference International Standards; gives an example for the designation
Aerospace — Self-locking nuts with maximum operating temperature greater than 425 degrees C — Test m...
Includes procedures for metric nuts with MJ threads and describes the test device and the method for each test. Other test devices or test procedures than those specified herein may be used. Shall be used in conjunction with the procurement specification laid down in ISO 8641. Applies to these nuts, provided that the relevant documents refer to this International Standard.
