RULES FOR THE CONSTRUCTION AND CLASSIFICATION OF FREIGHT CONTAINERS 2017
Chapter 1 General
The Rules for the Construction and Certification of Freight Containers(hereinafter referred to as “the Rules”) apply to containers complying with the International Standards ISO Series 1 Freight containers. Non-ISO containers or containers of special types not fully covered in the Rules are to be specially considered.
When authorized by an Administration, which is a signatory to the International Convention for Safe Containers(CSC), and upon request, the certification procedure may be extended and containers surveyed for compliance with the provisions of the convention, and certified thereto in the manner prescribed.
Terms and symbols used in the Rules are defined as follows unless otherwise specially provided：
(a)「最大操作總質量或額定R」係指貨櫃與其貨物之最大容許總合質量(單位公斤)，其重量則以Rg (單位：牛頓；g = 9.8m/s2)表示。
(b) Tare, T, is the mass (unit：kg) of the empty container.
(c)「最大允許貨物質量P」係R與T之質量(單位：公斤)差值，其重量以Pg(單位：牛頓；g = 9.8 m/s2)表示。
(d) Overall external dimensions are the maximum external dimensions of the container including any permanent attachments, and are designated by H, W and L (unit：mm) respectively.
(e) Internal dimensions are the minimum internal dimensions of the container including any permanent attachments except top corner fittings.
Container types are grouped according to the mode of transport, categories of cargo and the physical characteristics of the container and can be grouped into General cargo container, Specific cargo container(including thermal container, tank container, dry bulk container, and named cargo type container).

Chapter 3 Design
Overall external dimensions of all ISO series 1 freight containers have a unifying nominal width of 8 ft (2,438mm).
