Based on 49 CFR 178.925, the standards and requirements for rigid plastic Large Packagings (designated as type 50H) are as follows:
* Intended Use: They are intended to contain both liquids and solids.
* Material Quality: They must be manufactured from plastic material of known specifications, possessing a strength appropriate for their capacity and required service, and must conform to § 173.24.
* Resistance: The plastic materials must resist aging and degradation caused by ultraviolet (UV) radiation. If UV protection is needed, compatible pigments or inhibitors (such as carbon black) must be added and remain effective throughout the packaging's life.
* Additives: Other additives may be included to improve aging resistance or for other purposes, provided they do not negatively affect the material's physical or chemical properties. Retesting for changes in carbon black, pigment, or inhibitor content is allowed without retesting *only if* the changes do not adversely affect the physical properties of the construction material.
* Recycled Material Restrictions: You cannot use any used material in manufacturing, except for production residues or regrind from your own manufacturing process.
* Capacity Limits:
* They cannot have a volumetric capacity greater than 3,000 liters (793 gallons).
* They cannot have a volumetric capacity less than 450 liters (119 gallons).
