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. Usage type Converting from/to Examples β NOT REPRESENTATIVE OF ACTUAL WEIGHTS β ILLUSTRATIVE ONLY Length Ounces/foot to kg/m A coated wire that weighs 3 ounces per foot.
