The assembly process involves several stages based on the standard's guidelines: 1. Prepare six plywood panels to form the basic box structure. 2. Join these panels edge-to-edge to create the shook without battens. 3. Attach twelve battens internally at the bottom and top ends, securing each with three nails, totaling 24 nails for this step. 4. Fix remaining battens and accessories as specified in the referenced part of the standard. 5. Conduct a final inspection to ensure all nails and battens are firmly in place. 6. Proceed with packing the tea following the standard's packing instructions. This sequence ensures adherence to quality and structural integrity.
Assembly requires six plywood panels forming the box framework, twelve battens meeting specified dimensions, and metal fittings such as nails, screws, and corner straps as per the standard's accessory specifications. These materials conform to referenced parts of the overall standard to guarantee durability and proper packing performance. Ensuring the quality and standardization of these components is vital for the chest's integrity and suitability for tea storage and transport.
Packing varies depending on the tea grade and density: lighter teas like leaf tea are packed in larger chests, whereas denser teas such as dust tea require smaller containers. The weight-to-volume ratio for packed tea must not exceed 0.36 grams per cubic centimetre. This ratio helps determine the maximum permissible weight for a given chest volume, ensuring the tea is packed fully yet without overloading. The chests’ external dimensions should comply with the related parts of the standard to maintain uniformity and quality.
The standard mandates a maximum weight-to-volume ratio of 0.36 grams per cubic centimetre for the tea packed inside plywood chests. This means the weight of tea should not exceed 0.36 times the chest's internal volume in cubic centimetres. Smaller chests are designated for denser tea types like dust tea, while larger chests accommodate lighter teas such as leaf tea. Furthermore, the chest dimensions must conform to the related parts of the standard to ensure consistency and packing efficiency.
In assembling a standard 48 x 48 x 60 cm tea-chest, nails and fittings are distributed carefully for structural strength: Mitred face battens are fastened with 24 nails, straight battens with metal fittings use 72 nails, and the top and bottom panels secured with battens require 8 nails. 'V' notch metal fittings on the top and bottom panels require 112 nails each, plus an additional 32 nails for fixing side panels, totaling 232 nails overall. Nail placement follows specific spacing rules to optimize durability and ease of assembly, including spacing nails 3 to 7 cm apart and positioning nails at corners and midpoints as detailed in the standard.
