Compliance overview
Scope and applicability
This standard applies to the transportation of dangerous goods packaged in limited quantities within China. It is specifically designed for manufacturers, shippers, and carriers involved in the logistics and transport of hazardous materials by road, rail, water, and air. It does not apply to dangerous goods that are not listed in the standard's limited quantities table, as those substances are not permitted for transport under the limited quantity exception. The regulations cover a wide array of chemical products, including flammable liquids, toxic substances, corrosive materials, and gases.
Technical requirements
The standard establishes a comprehensive framework for the limited quantity transport of hazardous materials, aligning closely with the UN Recommendations on the Transport of Dangerous Goods. It defines the structure of the dangerous goods limited quantity table, which includes the UN number, proper shipping names, class or division, subsidiary risks, packing group, and the maximum authorized quantity per inner receptacle. For packaging, the standard mandates that goods must be packed in quality receptacles that can withstand normal transport conditions, including handling, vibration, and temperature changes. The total gross mass of a package must not exceed 30 kg, and specific requirements are set for inner and outer receptacles, particularly for fragile materials like glass or ceramics. Different dangerous goods may be packed together in the same outer receptacle only if they will not react dangerously in the event of leakage. The document also specifies marking and documentation requirements. For modes other than air transport, packages must display a specific diamond-shaped mark. For air transport, a similar mark with the letter "Y" is required. Transport documents must include the term "Limited Quantity" or "LTD QTY" for water and air transport. Furthermore, the standard provides certain exemptions, such as waiving segregation requirements within the same vehicle or freight container for limited quantity packages.
Testing methods
While this standard primarily focuses on listing and packaging requirements rather than specific laboratory testing procedures, it references the performance criteria for packaging as outlined in the UN Recommendations on the Transport of Dangerous Goods. The packaging must be designed and constructed to successfully withstand standard transport tests, including drop tests and stacking tests, ensuring the package's integrity under normal conditions of transport. The standard also details the general technical requirements for containers, such as ensuring sufficient ullage (unfilled space) for liquids to prevent leakage due to thermal expansion.
FAQs
What products are regulated under GB 28644.2-2012?
GB 28644.2-2012 regulates the transport of dangerous goods that are permitted to be shipped in limited quantities. This includes a wide variety of hazardous chemicals and materials listed in the standard's table, such as flammable liquids, toxic solids, corrosive substances, and compressed gases.
What is the maximum package weight allowed under this standard?
Under GB 28644.2-2012, the total gross mass of a package containing dangerous goods in limited quantities must not exceed 30 kg. For packages containing fragile inner receptacles like glass, porcelain, or stoneware placed in intermediate containers, the total gross mass must not exceed 20 kg.
Are there specific marking requirements for limited quantity packages?
Yes, packages must display a specific mark. For all modes of transport except aviation, a diamond-shaped mark with specific dimensions is required. For air transport, the mark must include the letter "Y" in the center. If packages are placed in an overpack, the overpack must be labeled "OVERPACK" unless the marks on all inner packages are clearly visible.
