Shrinkage after washing /chemical cleaning (follow cleaning advice!) LIGHTFASTNESS Lightfastness (the discoloration o.i. of sunlight) The degree of discoloration is expressed in a number between 1 and 8 on the blue scale, where 1 indicates the lowest lightfastness and 8 the highest lightfastness. In practice, a lightfastness of 6 means that the fabric may show slight discoloration after approximately 2 years (provided it is not exposed to direct sunlight). De Ploeg uses a lightfastness of 5 as its standard, while aiming for a lightfastness of 6.

SEAM AND SHEAR RESISTANCE
De Ploeg tests upholstery fabrics for sensitivity to ‘open up’ stitching.
In general, it can be said that a fabric whose fabric threads slide a maximum of 6 mm from each other will not cause any problems in practice. If the sliding resistance is less, then it is advisable to upholster extra carefully by using double stitching and pulling off the sides.
De Ploeg fabrics are tested for flame retardancy according to the standards used in different countries:
BS 5867 (Great Britain)
DIN 4102 (Germany)
NF 92 507 (France)
ISO 6940/6941 (International test)
