ISO 7770:2009 specifies a test method for evaluating the smoothness appearance of seams in fabrics, after one or several cleansing treatments. A seaming technique is not included, since the purpose is to evaluate existing seams.
This method has been developed for use primarily with type B domestic washing machines, as defined in ISO 6330, in the cleansing process. However, it may be possible to use it with type A machines, as defined in the same International Standard.
