This section defines the types of steel rails covered under the standard. It classifies rails primarily by their nominal weight per meter. For example, and JIS 60 are widely used designations internationally, representing approximately 50 kg/m and 60 kg/m rail profiles respectively. 2. Chemical Composition
To withstand the immense rolling loads of locomotives and bullet trains (Shinkansen), the steel chemistry must be strictly controlled. The PDF outlines the permissible percentage ranges for: : Provides hardness and wear resistance.
The standard includes detailed tables and figures for the following rail types (measurements in mm): jis e 1101 pdf
Sometimes, national standards are published or referenced through international organizations. The International Organization for Standardization (ISO) or the International Electrotechnical Commission (IEC) websites might provide links or references to equivalent or related standards.
The standard, titled "Flat bottom railway rails and special rails for switches and crossings of non-treated steel," is a critical Japanese Industrial Standard (JIS) that specifies the requirements for hot-rolled steel rails used in permanent ways . Document Versions and Status
The JIS E 1101 standard is not available for free. It must be purchased from official sources such as: For example, and JIS 60 are widely used
In 2019, following a legal amendment, the term "Japanese Industrial Standard" was officially changed to "Japanese Industrial Standard" (with the reading of "Kōgyō" changed to "Sangyō") in all documentation, though the technical content remained unchanged.
: Mandates chemical composition limits (Carbon, Manganese, Silicon, Phosphorus, Sulfur) to ensure optimal hardness and wear resistance.
Carbon steel profiles designed for high wear resistance. The PDF outlines the permissible percentage ranges for:
The 2001 revision, which remains the foundation for current versions, introduced several important changes:
The standard specifies strict chemical composition limits for each rail type to ensure proper material properties:
