Characteristics of the carpet & rug
GENERAL TECHNICAL DESCRIPTIONS
This General technical descriptions describe the technical basis for delivered products with regard to construction,measures, designs and colours etc.
1.- Construction data
For specified construction data it applies that with regard to test method and margins
they are in accordance with the valid European EN 1307 standard for textile floorings,
here under:
- The total weight indicates the total weight of the carpet in g/m². The margin is +/-15%.
- The pile weight indicates the yarn weight over the primary backing and is indicated in g/m². The margin is +15/-10%.
- The pile height indicates the pile´s height from the primary backing. The margin is: +15/-10%
2.- Measures
- Length: Standard lenghts are delivered with a margin of +/-1%. Special lenghts are delivered with a margin of +1/-0%. In case of total orders there may in some cases occur further surplus in a few rolls.
- Width: Standard widths are delivered with a margin of +/-1% for 366 cm & 400 cm roll width.
- Cuts: The margin for cuts (cut service) is +1/-0%. If a whole roll length has to be divided into more pieces the tolerance for the whole roll width will be +/- 3 cm
(e.g. a roll width of 397 cm (400 cm – 3 cm) divided into 4 even pieces to 4 lengths of 99 cm). - Area rugs: The length is delivered with a margin of +/-2% and the width with a margin of +/-2%.
- Modular: Lengths and widths are delivered with a margin of +/-0.2% within the same batch.
Patterns
Textile floorings are flexible floorings and like all production processes there are certain margins which have to be taken into consideration during installation.
The following criteria describe the max. margins within which it should be possible for a professional fitter to complete a satisfactory installation (see also Installation guide). The tolerances are valid trade standards in accordance with CEN/TS 14159:2014 which is a Technical Specification Document prepared by the European Committee for Standardization and thus valid for all members of the EU.
- Pattern repeats: The given repeat sizes indicate the measures of the dominating pattern both in the length and width direction. These are used when calculating additional material in case of possible joins of two or more lengths.
- Pattern displaced: Pattern fitting over full width is not guaranteed. When joining repeats in the length direction the margin is: +/- 0.5 % (cf. fig. 1).
- Pattern curves: Pattern curves appear where the repeat is on level in both sides but where the pattern is curving across the width of the carpet. The margin is +/-1% (cf. fig. 2).
- Diagonal slanting: Diagonal slanting appears where the repeat is out of level but staggered from one side to another. The margin is +/-1% (cf. fig. 3).
- Pattern swings: Pattern swings appear if the distance from the pattern to the carpet edge swings in the length direction. The margin is +/- 1%. However, max. 3 cm for 4 and 5 m width. Applies for standard roll length (cf. fig. 4).
Our carpets are tailored to meet the most exacting standards of design, color, and quality, created in close collaboration with some of the top architectural and design firms around the globe. Alarwool is committed to preserving jobs in Spain, with all of our manufacturing based at our state-of-the-art facility in Burgos, Spain. Remarkably, 90% of our production is destined for international projects.
Colours
- Colour deviation: Because of production conditions certain colour variations are inevitable. It is therefore possible that a shown sample may difference of colour to material delivered. It is important that rolls witch are to be fitted together must be from the same dye batch.
- It is the responsibility of the carpet fitter to examine the rolls prior to installation. In certain cases there may be minor colour differences from roll to roll. This can be due to minor colour differences in the production, different pile direction together with local conditions on the premises.
Other conditions
- Shading: By the notion shading is understood water spot like formations on the pile caused by changes in the original pile direction in velour qualities. In these areas where the pile of the carpet is moved in different directions, the light reflection of the material is altered. When the pile is moved one way it will appear darker and when moved in the opposite direction it will appear lighter. This is not a defect in manufacture. In consequence shading is not acceptable as a valid claim.
- Pile reversal: This appears where changes in the pile direction occur within a limited area compared to the original pile direction. The change of direction is very different to that of shading as above. The cause is unknown but it is generally considered not to be due to any defect in manufacture. In consequence pile reversal is not acceptable as a valid claim.
