The standard requires manufacturers to conduct various mechanical tests, including:
Note: While similar, the rail profiles (shapes) often differ slightly, meaning fishplates and fasteners must be matched specifically to the JIS profile.
"Design and Testing of Railway Rolling Stock in Compliance with JIS E 1101"
The JIS E 1101 standard defines the chemical composition, mechanical properties, and dimensional tolerances for various rail types. 1. Common Rail Types and Weights jis e 1101 pdf
In the world of railway engineering and industrial infrastructure, standards ensure safety, durability, and compatibility. One of the most significant standards for railway tracks is the , a Japanese Industrial Standard (JIS) that specifies the technical requirements for rails used in permanent ways.

| Rail Type | Mass (kg/m) | Key Dimensions | |-----------|-------------|----------------| | | 37.2 | Height A: 122.24 mm, Width B: 122.24 mm | | 40 kgN rail | 40.9 | Height A: 140.00 mm, Width B: 122.00 mm | | 50 kgN rail | 50.4 | Height A: 153.00 mm, Width B: 127.00 mm | | 60 kg rail | 60.8 | Height A: 174.00 mm, Width B: 145.00 mm |
: The 'N' in 40kgN and 50kgN stands for "new" shape, which features an improved head profile for better wheel-rail contact.
