Introduction
Standard Background and Scope of Application
This standard replaces the original industry specifications and provides technical upgrades based on the special requirements of rescue packaging and large packaging. It is mainly applicable to the inspection and supervision of import and export dangerous goods transport packaging.
Definition of core terms
| Terms | Definition | Technical parameters |
|---|---|---|
| Rescue packaging | Special containers for leaking dangerous goods | ≤3000L volume |
| Large packaging | Transport packaging exceeding conventional size | ≥400kg or ≥450L |
Key performance requirements
Sealing test
All class=instrument>Rescue packaging must pass a 98% pressure holding rate test, and the test method refers to the AQL standard of GB/T2828.1.
Stacking test
The packaging needs to withstand a pressure of 30kPa for 24 hours without deformation. Specific requirements:
- ≤30kg packaging: stacking height ≥12mm
- ≤5kg packaging: exempt from stacking test
Labeling specifications
Must include the following elements:
- United Nations number (UN number)
- Packaging type code (such as "T")
- Production batch identification
- "Rescue" wording (height ≥12mm)
Comparison of old and new standards
| Project | SN/T4897-2017 | Old version of the standard |
|---|---|---|
| Test sample size | According to the secondary scheme of GB/T2828.1 | Fixed ratio sampling |
| Pressure test | Add vacuum test | Positive pressure test only |
Implementation suggestions
Enterprise response strategies
- Establish a packaging material traceability system
- Update the pressure calibration range of testing equipment
- Train personnel to master the new sampling rules
Troubleshooting of common problems
When compatibility issues with adsorbent materials arise, compatibility testing should be carried out in accordance with Appendix B of the standard.
