Pickering Laboratories Inc Artificial Perspiration, DIN 53160, BS EN 1811:2011, Buffered, Custom pH, Not Stabilized, each (200 mL/bottle).

Supplier: Pickering Laboratories Inc 17000569

Method DIN 53160-2:2010-10 specifies an artificial perspiration solution that is used to determine the colorfastness of articles for common use. The test method is applicable to all articles of daily use, independent of the coloring procedure applied (dyeing, staining or coating). Method BS EN 1811:2011 is used for the testing of nickel release from jewelries and other products that come with prolonged contact with skin. The primary perspiration components and pH described by methods BS EN 1811:2011 and DIN 53160-2:2010-10 are the same, we now offer a buffered version of the original formulations. Phosphate ions do not affect color migration rates nor the rate of nickel release, so these modified formulations can be used for the same tests. The buffered formulation is offered at pH 6.5, specified by DIN 53160 and BS EN 1811:2011 methods.
