Food products — Guidance on how to express vitamins and their vitamers content
This document provides guidelines on:
— how to express vitamin quantity,
— the expression of different molecular forms in appropriate units,
— and in some cases, vitamin activity, according to vitamers present or used in food products, in addition to the quantitative content determination obtained from ISO and CEN analytical standards.
It provides information to be used as a basis for discussion…
Household electric cooking appliances - Part 1: Ranges, ovens, steam ovens and grills - Methods for ...
IEC 60350-1:2016+A1:2021 specifies methods for measuring the performance of electric cooking ranges, ovens, steam ovens, and grills for household use. The ovens covered by this standard may be with or without microwave function. Manufacturers should define the primary cooking function of the appliance microwave function or thermal heat. The primary cooking function should be measured with an…
