ISO 105-A01 to A05

ISO 105-A01:2010 provides general information about the methods for testing colour fastness of textiles for the guidance of users. The uses and limitations of the methods are pointed out, several terms are defined, an outline of the form of the methods is given and the contents of the clauses constituting the methods are discussed. Procedures common to a number of the methods are discussed briefly.
ISO 105 A02 : Describes the grey scale for determining changes in colour of textiles in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. The essential scale (5 steps) consists of pairs of non-glossy grey colour chips (or swatches of grey cloth). In addition, an augmented scale includes four half-steps and, thus, 9 steps.
ISO 105 A03 :Describes the grey scale for determining staining of adjacent fabrics in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. The essential scale (5 steps) consists of pairs of non-glossy grey or white colour chips (or swatches of grey or white cloth). In addition, an augmented scale includes four half-steps and, thus, 9 steps.
ISO 105-A04:- Tests for colour fastness. Method for the instrumental assessment of the degree of staining of adjacent fabrics
ISO 105-A05:-Instrumental assessment of change in colour for determination of grey scale rating.Specifies an instrumental method for assessing the change in colour of a test specimen in comparision to an identical untreated reference, and the calculations undertaken to convert the instrumental measurements into a grey scale rating.
ISO 105-F09:2009 specifies a cotton rubbing cloth which can be used for the assessment of staining in colour fastness to rubbing tests. The staining properties of the cotton rubbing cloth under test are assessed against a cotton rubbing cloth reference fabric, using a cotton dyed reference fabric, both of which are available from a specified source.
