Описание (английский):

ISO 19699-1:2017 specifies the testing methods for the properties of superabsorbent polymer (SAP) of sodium polyacrylate used in physical hygiene and medical products for absorbing blood. It also gives a formulation for simulated blood, a kind of viscous liquid, for replacing blood when testing the properties of the superabsorbent polymer. The test methods and simulated blood in this document apply to sodium polyacrylate resin, as raw material, and apply to SAP for the final products used for absorbing blood.

Overview

ISO 19699-1:2017 defines standardized test methods for superabsorbent polymer (SAP) products based on sodium polyacrylate intended to absorb blood. The document covers laboratory procedures, sampling, required apparatus and a formulation for simulated blood used to replace human blood during testing. It applies to sodium polyacrylate resin as raw material and to SAP in final hygiene and medical products.

Key topics and technical requirements

Scope and applicability: Test methods specific to sodium polyacrylate SAP used in physical hygiene (e.g., sanitary pads) and medical products (e.g., tourniquets, surgical dressings).

Core property tests:

Amount of residual monomers (reference to ISO 17190-2)
Volatile content / moisture (ISO 17190-4)
pH measurement (ISO 17190-1)
Particle size distribution (ISO 17190-3)
Bulk density (ISO 17190-9)
Whiteness measured by ISO 2470-2 reflection method

Simulated blood tests:

Simulated blood absorption capacity: mass-based gravimetric test using a polyamide “tea bag” with defined sample mass; standard specifies sampling, immersion (30 min), drip period (10 min), weighing and calculation (g simulated blood per g resin). Annex A gives the simulated blood formulation; Annex B compares simulated vs human blood absorption.
Simulated blood absorption rate: time for 1 g of SAP to absorb 5.0 ml simulated blood (method details in the standard).

Sampling & safety: Representative sampling procedures from bulk shipments and precautions (respiratory protection for >10 g handling).

Normative references and traceability: links to related ISO test methods and analytical standards.

Note: ISO 19699-1:2017 draws attention to possible patent claims on some simulated blood test methods; the patent holder has declared willingness to license under reasonable terms.

Applications - who uses this standard

SAP manufacturers for quality control of sodium polyacrylate resin

Hygiene product and medical device manufacturers verifying absorbency performance for blood-contacting products

Independent testing laboratories and QA departments conducting acceptance and batch testing
