Hammer Carpets' general technical terms and conditions of sale are a supplement to the valid general terms and conditions of sales. The general technical terms and conditions describe tolerances, patterns, colours, etc. in more detail.
CEN/TS 14159:2007:CEN/TS 14159:2007 stipulates, for example:
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.
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.
