___________
SC 59K interpretation sheet on: Volume measurement in IEC 60350-1:2016

Rationale
When measuring the oven volume in accordance with IEC 60350-1:2016, 6.2, the wording in
the standard leaves room for interpretation as to how to proceed with side grids in the oven.
In many regions, the volume is used to calculate an energy efficiency index, which always
raises the question as to what extent the measurement with and without side grids leads to
different statements on energy efficiency.
This document clarifies how to interpret 6.2 of IEC 60350-1:2016 in order to achieve a clearer
approach.

Question
According to IEC 60350-1:2016, 6.2, removable items, e.g. the side grids, shall be removed to

measure the volume if this is indicated in the user manual. The question that arises is to

ascertain when this condition is met, and when the measurement is performed without side

grids.
Answer
The usable width of the oven is measured in accordance with 6.2.3 from the left side wall of

the cavity to the right side wall of the cavity. In accordance with 6.2.1, parts, such as side

grids, shall be removed before the measurement if they are removable and if they are not
necessary for any intended operation, in accordance with the user manual.
As a result, side grids shall be removed if:
1) the user manual describes the removal of side grids (the extent of the description and
the assignment to a chapter is not defined);
2) the user manual describes any application for which the removable parts are not
required (= intended operation). This is the case when an application on the bottom of
the cavity without the use of side grids is given as an example. The number of
applications as well as the type of application (heating type, temperature, minor
relevance, preheated operation) are not specified in 6.2.1 and are, therefore,
irrelevant.
