Information technology for learning, education and training — Online course information model
This document provides the means for understanding the information model of online course, and demonstrates the basic elements and their descriptions. It is the foundation for conceptual understanding of online course and instructional behaviours in online education. This document can be applied to the design and development of online courses, which are supposed to be migrated and shared between…
Coffee and coffee products — Determination of acrylamide — Methods using high-performance liquid chr...
ISO 18862:2016 specifies methods for the determination of acrylamide in coffee and coffee products by extraction with water, clean-up by solid-phase extraction and determination by HPLC-MS/MS and GC-MS. It was validated in a method validation study on roasted coffee, soluble coffee, coffee substitutes and coffee products with ranges from 53 μg/kg to 612,1 μg/kg.
Soil quality — Estimation of abundance of selected microbial gene sequences by quantitative polymera...
ISO 17601:2016 specifies the crucial steps of a quantitative real-time polymerase chain reaction (qPCR) method to measure the abundance of selected microbial gene sequences from soil DNA extract which provides an estimation of selected microbial groups.
It is noteworthy that the number of genes is not necessarily directly linked to the number of organisms that are measured. For example, the…
Habillement de protection — Exigences de performance pour les vêtements de protection portés par les...
L'ISO 27065 établit les exigences de performance minimale, de classification et de marquage pour les vêtements de protection portés par les opérateurs manipulant des pesticides ainsi que par les travailleurs de rentrée. Aux fins de l'ISO 27065, le terme «pesticide» s'applique aux insecticides, herbicides, fongicides et autres substances appliquées sous forme liquide qui sont…
Biocombustibles solides — Classes et spécifications des combustibles — Partie 5: Classes de bois de ...
Le présent document détermine les classes et spécifications de qualité du combustible pour le bois de chauffage. Le présent document couvre uniquement le bois de chauffage produit à partir des matières premières suivantes (voir ISO 17725-1:2021, Tableau 1):
— 1.1.1 Arbres entiers sans racines;
— 1.1.3 Grumes;
— 1.1.4 Rémanents forestiers (grosses branches, cimes, etc.);
— 1.2.1…
L'ISO 14532:2014 a pour objet de donner les définitions, symboles et abréviations utilisés dans le domaine du gaz naturel.
Les termes et définitions ont été étudiés et revus de manière à couvrir toutes les acceptations particulières des termes provenant également d'autres sources telles que les normes européennes du CEN (Comité Européen de Normalisation), les normes nationales et les…
Determination of the characteristic limits (decision threshold, detection limit and limits of the co...
The ISO 11929 series specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the "decision threshold", the "detection limit" and the "limits of the coverage interval" for a non-negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross…
