28、v ISO 2017 All rights reserved ISO 19699-1:2017(E)IntroductionThe test methods described in this document have been practically used by relevant production enterprises for several years and have proven to be reliable with respect to common criteria of quality of test methods (validity, repeatability
29、, etc.). They are applicable to testing superabsorbent polymer of sodium polyacrylate used in hygiene products (such as sanitary towels and pads) and medical products (such as tourniquets and surgery coats).The International Organization for Standardization (ISO) draws attention to the fact that it
30、is claimed that compliance with this document may involve the use of a patent concerning test methods of simulated blood absorption capacity and simulated blood absorption rate given in 4.8 and 4.9.ISO takes no position concerning the evidence, validity and scope of this patent right. The holder of
31、this patent right has assured ISO that he/she is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with ISO. Information may be obtained from
