Introduction
Interpretation of the core content of the standard
This standard specifies the method for determining the ability of toilet paper and its products to resist mechanical penetration in a wet state. The technical points include:
| Key indicators | Definition | Unit | Test conditions |
|---|---|---|---|
| Wet spherical bursting strength (FW) | The maximum vertical force value that the sample can withstand after being wetted | mN | 125mm/min speed |
| Burst index (XW) | FW to quantitative ratio | mN·m²/g | Standard atmospheric conditions |
| Retention rate (WR) | Wet/dry burst strength ratio | % | Comparison of the same sample |
Technology evolution analysis
Compared with ISO12625-11:2012, this standard has the following major adjustments:
- Delete the reference to ISO7500-1 on force measurement system calibration in the international standard and adopt the domestic general method
- Simplify the definition of terms to be more in line with the Chinese context (such as translating "ball burst strength" into "ball burst strength")
- Add a graphic illustration of the pneumatic clamping system to improve operability
Implementation suggestions
Case: The test result of a certain brand of kitchen paper towels showed FW=3783mN. After calculation, XW=12.4mN·m²/g and WR=82%, indicating that the product:
- Maintains high mechanical strength in wet state
- The addition of wet strength agent has a significant effect
- Meets the requirements of GB/T24328.9 for superior products
Notes:
- Before testing, it is necessary to soak with deionized water with conductivity≤0.25mS/m
- It is recommended to conduct accelerated aging treatment at (80±2)℃/30min for new production samples
- The rubber hardness of the clamping ring should be controlled within the range of 70-85IRHD
