Household and similar bread slice electric roaster
Performance test method
1 range
This standard applies to bread and electric roasters for household and similar purposes.
Note. For example, a sandwich oven with a bread baking function, an electric oven, a toaster, etc. belong to a bread slice electric roaster.
The purpose of this standard is to describe and define the main performance characteristics of the bread toasters of interest to the user, and to describe the criteria for measuring these characteristics.
Quasi-methods and give some guidelines for evaluating test results.
The low level of accuracy and reproducibility is due to differences in time and source of test materials and ingredients, as well as the test operator
The influence of subjective judgments, the test methods described can be more reliably applied to comparative tests of a batch of appliances, in roughly the same time,
In the same laboratory, the same operator uses the same utensils for testing, rather than using the same instrument in different laboratories.

This standard does not address safety.
This standard does not apply to appliances used solely for commercial or industrial design.
