Dentistry — Coupling dimensions for handpiece connectors — Part 1: Mechanical properties
This International Standard specifies the coupling between handpieces and motors connected to dental units.
This International Standard specifies the nominal dimensions, tolerances and the extraction force of coupling systems for use between handpiece and motor which supply the handpiece with water, air and light, and rotation energy.
Vegetable fats and oils — Isomeric diacylglycerols — Determination of the content and relative amoun...
This International Standard specifies the determination of the degree of isomerization of diacylglycerols in vegetable fats and oils. 1,2-diacylglycerols are transformed to the more stable 1,3-isomers during storage or due to acidic catalyzed reaction.
The mass fraction of 1,2-diacylglycerols can be used as a quality criterion for vegetable fats and oils. The absolute content of diacylglycerol…
Dentistry — Endodontic instruments — Part 8: Accuracy of electronic apex locator
This part of ISO 3630 specifies requirements and test methods for the accuracy of electronic apex locators that are used to determine the apical foramen (‘apex’ in this document) location during endodontic treatment. Integrated types of electronic apex locators are excluded from this standard.
Information technology — International string ordering and comparison — Method for comparing charact...
This document defines the following.
— A reference comparison method. This method is applicable to two character strings to determine their collating order in a sorted list. The method can be applied to strings containing characters from the full repertoire of ISO/IEC 10646. This method is also applicable to subsets of that repertoire, such as those of the different ISO/IEC 8-bit standard…

ISO 1629:2013 establishes a system of symbols for the basic rubbers in both dry and latex forms, based on the chemical composition of the polymer chain. The purpose is to standardize the abbreviated terms used in industry, commerce and government, and it is not intended to conflict with, but rather to act as a supplement to, existing trade names and trademarks.
Hydraulic fluid power — Fluid contamination — Determination of particulate contamination by the coun...
This International Standard specifies methods for determining the level of particulate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems.
Particle sizes greater…
