ISO 17190 discusses polyacrylate superabsorbent powders for urine-absorbing aids for incontinence. ISO 17190-5 provides a test method that determines the free swell capacity of polyacrylate superabsorbent powders in saline solution.
A bag is submerged in the fluid to be absorbed and allowed to soak for a defined soaking period, after which the bag is removed. Excess fluid is allowed to drip away, and the sample is weighed to determine the amount of fluid absorbed.
Note: ISO 17190-5 does not claim to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It is expected that the person performing this test has been fully trained in all aspects of this procedure.
ISO 17190-5 on swell capacity in saline for polyacrylate superabsorbent powders is useful for:
Why should you use ISO 17190-5?
Polyacrylate superabsorbent powders absorb water or urine by a process called osmosis. When the polymer is placed in urine, there is a tendency for the atoms contained in the powder to distribute equally between the network and water. Extractables are the sum of the soluble acid and salt groups of monomeric, oligomeric, and polymeric carboxylates extracted from the superabsorbent polymer
ISO 17190-5 guidelines provide requirements for Water, Sodium hydroxide solution, Hydrochloric acid solution, Sodium chloride solution, Standard buffer solutions, sampling, procedure, calculations, reports, precision for the determination of the free swell capacity in saline by gravimetric measurement in polyacrylate powder. This helps in conducting proper assessment and provides reliable results on the determination of the free swell capacity in saline by gravimetric measurement in polyacrylate superabsorbent powder that can be reproduced in any laboratory.
