Introduction
Interpretation of core technology
Breakthrough point of the standard: For the first time, the rotational compression and compound kneading mechanism was included in the national standard system, and a quantitative evaluation model was establishedAnalysis of comparative test mode
| Mode code | Stroke type | Number of times | Application scenario |
|---|---|---|---|
| Mode A | Long stroke | 2700 times | Ultra-heavy load transport packaging certification |
| Mode D | Long stroke | 20 times | E-commerce express packaging inspection |
Key instrument parameters
The core component adopts a linear axis (90±1mm) and rotation axis composite motion system, with a spacing accuracy of ±1mm. The support arm is designed with a self-balancing adjustment device to ensure that no additional stress is generated during testing.
Technology Evolution Analysis
Compared with the JIS Z 1707-1997 uniaxial kneading method, this standard innovatively introduces:
- Three-dimensional kneading simulation (rotation axis 440° + linear axis sliding)
- Dual evaluation system (visible pinhole quantification + microscopic gas penetration dual verification)
Actual installation case: After a certain brand of puffed food bags was tested using this standard, the packaging breakage rate decreased by 57%
Implementation Suggestions
Key quality control points:
- Each batch of dyed turpentine should be compared with the standard color card
- The rubbing frequency needs to be calibrated by laser speed measurement every month
- The pinhole counting area must use a matte white background plate (reflectivity ≤ 30%)
