ISO 18265: "Metallic materials — Conversion of hardness values" (2013) ASTM E140-12B(2019)e1: "Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness" (2019)
Barcol hardness is measured on a scale from 0 to 100 with the typical range being between 50B and 90B. A measurement of 60B is roughly equivalent to a Shore hardness of 80D or a Rockwell hardness M100. [4] [6] As defined in ASTM D 2583 the scale divisions from 0-100 should each indicate a depth of 0.0076 mm or the equivalent 0.0003 inches. [7]

The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters. It is commonly abbreviated as Fr but may also be abbreviated as Fg , FR or F , and less frequently as CH or Ch (referencing its inventor, Charrière ).
The SI unit, pascal, is sometimes used instead: 1 kg f ⋅mm −2 = 9.80665 MPa. The test was developed by Frederick Knoop [ 2 ] and colleagues at the National Bureau of Standards (now NIST ) of the United States in 1939, and is defined by the ASTM E384 standard.
