Tolerances
Specifications
- Where test methods and results are concerned, all our specifications meet the provisions of the applicable European standard for textile floor coverings.
CEN/TS 14159:2007:
CEN/TS 14159:2007 stipulates, for example:
Total weight: Acceptable tolerance +/- 15%
Pile weight: Acceptable tolerance +/- 15%/-10%
Pile height: Acceptable tolerance +/- 1 mm
Measurements
- Length:
All stock items with a standard length measure are delivered with a tolerance of +/-0,5%. Rolls in special lengths are delivered with a tolerance on +2%/-0%. All lengths in stock exceeding 18 lm are regarded and invoiced as rolls. - Width:
All stock items with a standard width (366 cm, 400 cm and 500 cm) are delivered with a tolerance of +/- 3 cm. - Cut:
All lengths less than 18 lm. These are delivered with a tolerance of +1%/-0%.
Patterns
- Repeat:
A pattern repeat indicates the measurements of the dominating pattern in both width and length direction. - Displacement
The tolerance for joining pattern repeats in the longitudinal direction is +/- 0,5%. - Torsion:
The tolerance for pattern torsion is +/- 1%. (i.e. the pattern repeat is not the same height on both sides). - Curves:
Pattern curves may appear where the pattern is at the same height in both sides of the roll, but curves across the width of the carpet. The tolerance for this is +/-1%. - Swings:
If the distance from the pattern to the edge of the carpet swings in the longitudinal direction, the tolerance is +/- 1%.
Dye colour
- Shade deviation:
Shade deviations are inevitable when changing from one production batch to another. Therefore slight changes can be seen between a pegboard/sample and the manufactured goods delivered. When fitting several rolls in the same room, it is important to order rolls from same dye batch/production lot. The orderer must ascertain that this is so. The carpet fitter is responsible for checking the rolls before cutting and fitting. Shading:
The term refers to water-like spots in the carpet which is due to areas where the original pile direction changes. This phenomenon is seen in velour qualities. Depending on light sources and light influences, dark areas that deviate from the general design expression may appear. This is not a production fault and is not acceptable as a valid claim.Pile reversal:
This is seen in a clearly limited area where there is a change in the pile direction compared to the original pile direction. The optical effect of this
change is more visible than shading (see above). The reason for this phenomenon is not known. It is not considered a production fault and is not acceptable as a valid claim.
Quantities
- Roll lengths:
When the customer orders rolls at roll price, we offer roll lengths which are available in stock. If the customer requires other roll lengths, these can be supplied within the normal tolerances (see above) in the next production batch of the quality requested. If the rolls in stock need to be cut, they will be invoiced at cut price. - Special orders:
When producing special orders (= non-stock items), a maximum of 3% surplus production is calculated. If the surplus production exceeds 3%, this quantity may be dispatched with the order free of charge. The 3% surplus will be invoiced and sent with the rest of the order. If the surplus production exceeds 3%, the excess quantity may be dispatched with the order free of charge.
