JIS E 1101 is particularly famous for its , which extends rail life on tight-radius curves—a necessity in Japan’s mountainous terrain.
The standard covers several rail classes based on weight and application. Below is a summary of the common rail profiles specified under : Nominal Weight (kg/m) Height (mm) Base Width (mm) Head Width (mm) JIS 30A JIS 37A JIS 40N JIS 50N JIS 60kg Material and Mechanical Properties
: This standard is based on the first edition of ISO 6008 , ensuring technical alignment with international requirements for non-treated steel rails .
Verifying that a shipment of steel meets Japanese law.
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
