FAQ
(1) What does absorption speed indicate in hygiene product testing?
Absorption speed reflects how quickly a product can take in liquid under defined conditions. According to GB/T 8939, it is measured as the time required for a fixed volume of liquid to be fully absorbed, which directly impacts user comfort and leakage prevention.
(2) How is the test liquid volume determined?
Standards such as ISO 11948-1 specify test volumes based on product type and structure. Typical volumes range from 5 mL to 20 mL, ensuring consistent comparison across products while simulating realistic usage conditions.
(3) Why is pressure applied during testing?
A controlled load (e.g., up to 500 g) simulates real-use conditions where the product is under body pressure. This affects liquid distribution and absorption rate, making results more representative of actual performance.
(4) What factors affect test repeatability?
Repeatability depends on liquid dispensing accuracy (±0.1 mL), timing precision (0.01 s), sample placement, and pressure consistency. Proper calibration and adherence to standard procedures are essential for reliable results.
(5) How to select a suitable tester for laboratory use?
Key considerations include compliance with GB/T or ISO standards, measurement precision, automation level, and data management capabilities. For applications requiring consistent and traceable results, automated systems are recommended. For selection support, contact QINSUN engineers.
