Mass Determination
Standardized moisture calculations establish the legal mass of textile materials by adding an agreed percentage allowance to oven-dried fiber weight. In raw flax trading and mill inventory accounting, commercial dry weight establishes the contractual basis for calculating transaction values. Commercial transactions apply an official moisture regain allowance of twelve percent to absolute dry flax fibre mass.
The metric standardizes billing across shipments exposed to fluctuating atmospheric humidity during transit. Calculations govern financial invoicing, terminating at the boundary where raw fiber transforms into spun yarn stock.
Invoice Settlement
Oven drying testing procedures determine the zero-moisture baseline required for commercial billing calculations. Laboratory technicians draw core samples from sealed fiber bales, drying the samples at one hundred five degrees Celsius until mass stabilizes completely. Multiplying this bone-dry mass by one point one two yields the commercial dry weight for the entire shipment.
Buyers calculate final invoice payments using this standardized value rather than the fluctuating gross weight recorded at receiving docks. Financial adjustments compensate for water weight gained or lost during transit, protecting both buyer and seller from ambient humidity changes.
Regain Limit
Excessive ambient moisture absorption beyond official regain allowances invalidates standard billing formulas. When raw flax shipments arrive with moisture content exceeding fifteen percent, buyers invoke re-testing clauses or apply monetary penalties. The commercial dry weight calculation applies strictly to raw scutched flax and hackled line fiber trading.
