Tolerances
The following production tolerances are to be taken into consideration:
Quantity tolerance for paper
± 3% however a minimum of ± 5 sheets per sales unit
Quantity tolerance for board materials, corrugated board
± 3%
Quantity tolerance for enclosures, folders, boxes
± 8%
Weight (grammage) tolerance
± 7%
Thickness (calliper) tolerance
Paper and board up to 300 gsm ± 10%
Board > 300 gsm ± 5%
Corrugated board ± 8%
Dimensional tolerances for paper and board material
Sizes (formats) with plus tolerance max. ± 7 mm
Cutting tolerance 4-sided angular cut ± 2 mm
Dimensional tolerance for corrugated board
Cutting tolerance ± 3 mm
Dimensional tolerance for honeycomb panels
Cutting tolerance ± 5 mm
Dimensional tolerances for reeled paper
Roll width ± 5 mm, running metres ± 3%
Dimensional tolerance for enclosures, folders, boxes
Plus tolerance up to 5%
Dimensional tolerances for envelope enclosures
Angle tolerance ± 2 mm, size tolerance ± 3 mm
Dimensional tolerances for tubes
Diameter and tube wall thickness ± 0.3 mm,
Lengths ± 10 mm
Perpendicularity tolerances for cuttings with 4-sided angular cut
Angle tolerance 0,6% however a minimum of 3 mm over a length of 1 m
Planarity tolerance for corrugated board
Planarity (flatness) tolerance ± 15 mm for 1 m length
Spots (fibre residues and pulp impurities)
Spots with a diameter of less than 0.4 mm are considered insignificant.
Mounting board standard specifications stipulate that maximum two spots
up to 0.9 mm in diameter each are acceptable per m².
pH tolerances
± 0.5 variation on the pH scale (pH 7.0, pH 6.5 and 7.5 are also permitted)
Deviating tolerances are to be agreed upon separately.
