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…

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.

This standard is developed to link product engineering and the successful performance of an autonomous underwater vehicle, especially for “extreme missions”. An extreme mission being a relative term can be seen as any underwater expedition that is increasing in difficulty level. While these vehicles have been and are being manufactured by many companies all around the globe for several decades,…

Within the general scope described in ISO/IEC 9995-1, ISO 9995-9:2016 defines the allocation on a keyboard of a set of graphic characters which, when used in combination with an existing national version keyboard layout, allows the input of a minimum character repertoire as defined herein. This repertoire is intended to address all characters needed to write all contemporary languages using the…

1.1 This International Standard specifies the requirements for seal-less rotodynamic pumps that are driven with permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment or safety regulations. Seal-less pumps are pumps where an inner…

This International Standard specifies methods for evaluating the performance of engines designed for motorcycles as defined in ISO 3833, in particular with a view to the presentation of power curves and specific fuel consumption at full load as a function of engine speed, for net power assessment. It is applicable to reciprocating internal combustion engines (spark-ignition or compression-…

This standard would provide general requirements and guidance for the development and application of LAMP-based methods for the detection of microorganisms and associated genetic markers sampled along the food chain (e.g., ingredients, human food, animal food, and the production environment), and includes sample preparation, isothermal amplification, signal detection, data interpretation, and…

This part of IEC 62264 specifies generic interface content exchanged between manufacturing control functions and other enterprise functions. The interface considered is between Level 3 manufacturing systems and Level 4 business systems in the hierarchical model defined in IEC 62264-1. The goal is to reduce the risk, cost, and errors associated with implementing the interface. Since this standard…

1 Scope Replacement This part of IEC 61558 deals with the safety of isolating transformers for general applications and power supply units incorporating isolating transformers for general applications. Transformers incorporating electronic circuits are also covered by this document. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here…

This part of ISO 5267 specifies a method for determination of the drainability of a pulp suspension in water in terms of the "Canadian Standard" freeness in millilitres. In principle, this method is applicable to all kinds of pulp in aqueous suspension. NOTE Treatments which produce a large proportion of fines may induce an anomalous rise in freeness (false freeness), as a rule at…
