Container flooring Vietnamese Plywood is a type of board manufactured from hard junk wood, oilwood board, using waterproof glue, produced by hydraulic pressing technique at high pressure…In addition, it also has standards to be able to choose more suitable products.
1. Standard organization of container flooring:
IICL stands for The Institute of International Container Lessors. It is an association of companies that supply and lease containers and container chassis. IICL was founded in 1971 in the United States. The organization represents its members in areas such as government, regulations, customs, taxes, education, technology, and environmental matters.
IICL carries out its work through two main committees: the Technology Committee and the Tax and Legal Committee. These committees include representatives from member companies, along with staff at IICL’s headquarters.
The International Maritime Organization (IMO) recognizes the Institute as a Non-Governmental Organization (NGO). IICL also works closely with other global organizations such as the International Organization for Standardization (ISO), the World Customs Organization (WCO), the UN Economic and Social Council, and the UN Conference on Trade and Development (UNCTAD). Additionally, it collaborates with regulatory bodies worldwide.
2. What are the T5, T6, T7 standards of container floors?
From January 15, 2019, 20 container flooring manufacturers agreed to print additional information T 7, T 6 and T 5 on the edge of the floorboard where T 5, T 6 and T 7 are defined as the table below:
| Standard |
ISO Bearing Level |
|
T7 |
>7.2 tons |
|
T6 |
6.0-7.2 tons |
| T5 |
5.0-6.0 tons |
Regulations of IICL B001 2019 on container flooring specifications
A. Core veneer:
- 19 layers is the minimum quantity for plywood and bamboo floorboards.
- Unless the customer specifies a specific structure, manufacturers can use any layer of wood to produce flooring that meets all the requirements of this regulation as well as ISO standards
WARNING: The longitudinal wood layer has flexural and shear strength. They are used for cont floorboards in the roof, floor and core of the floorboard.
- Adding more than three outer longitudinal wood layers (top and bottom) may cause surface cracks on some panels. Increasing the center layers from one to three slightly improves panel stiffness and is expected to boost resistance to cutting, a common cause of container floor failure. However, these improvements are not always consistent
B. Core veneer quality:
The top layer must be 1 solid sheet. If the surface of the flooring is covered with film or similar coverings, the laminate must also be a solid sheet.
C. Humidity:
- According to BS EN 322, the humidity must not exceed 14% at the time of introduction into production
- Each board should have all edges glued with an external varnish or an equivalent coating to minimize moisture
D. Density and Specific gravity:
- At least 700 kg/m3 at the time of production
- Specific gravity: at least 0.70 at the time of manufacture.
