The method is described in the similar standards ASTM D1238 [3] and ISO 1133. [ 4 ] Melt flow rate is a measure of the ability of the material's melt to flow under pressure, and is an indirect measure of molecular weight, with high melt flow rate corresponding to low molecular weight.

ASTM F1249 - Standard Test Method for Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor ASTM F2298- Standard Test Methods for Water Vapor Diffusion Resistance and Air Flow Resistance of Clothing Materials Using the Dynamic Moisture Permeation Cell
Some conditions and procedures that have to be met, according to DIN ISO 7619-1 standard are: For measuring Shore A the foot indents the material while for Shore D the foot penetrates the surface of the material. Material for testing needs to be in laboratory climate storage at least one hour before testing. Measuring time is 15s.
The governing standard for the Barcol hardness test is ASTM D 2583. [4] 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.
In Europe, ISO 180 methods are used and results are based only on the cross-sectional area at the notch (J/m 2). The dimensions of a standard specimen for ASTM D256 are 63.5 × 12.7 × 3.2 mm (2.5 × 0.5 × 0.125 in). The most common specimen thickness is 3.2 mm (0.13 in), but the width can vary between 3.0 and 12.7 mm (0.12 and 0.50 in).

The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.
