MassFraction #74

Closed GerhardHNL closed 2 months ago

GerhardHNL commented 7 months ago

A numeric value representing the mass fraction of the product represented by this material. The sum of all mass fraction values for a given passport should be 100.

Remark: Mathematically, mass fraction is calculated as the mass of the component of interest divided by the total mass of the mixture or material, expressed as a fraction or percentage. --> Therefore, the sum of all mass fraction values for a given passport should be 1.

Would adding the weight of a component material be worthwhile in this context? E.g. Virgin Cotton, Material Weight 1 KGM, Mass Fraction 0,5.
Organic Cotton Material Weight 1 KGM , Mass Fraction 0,5.

yes, fair point. Should sum to 1 not to 100.

I think this one can be closed. Point accepted and updated in the spec.
