WHAT IS SPECIFIC WEIGHT AND HOW SHOULD THE INFORMATION
BE ENTERED?
In Recommendation 001, you are now required to enter the specific weight of the semicomponent. This is the specific weight in scientific terms used for further calculations
and not the weight of a semi-component. Semi-components do not have a weight until
they are further processed. This value is so you or your customer can easily calculate
the weight of the semi-component when added to the component.
Rule 4.3.1.B
In semi-components created since release of IMDS 7.0, the
usage weight type (kg/m, kg/m² or kg/m³) of the semi-component
must be entered.
For those working in countries that do not use the metric system, this will require you to
perform some mathematical calculations.
