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.
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).

ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.

The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
The Standard methods for Notched Bar Impact Testing of Metallic Materials can be found in ASTM E23, [8] ISO 148-1 [9] or EN 10045-1 (retired and replaced with ISO 148-1), [10] where all the aspects of the test and equipment used are described in detail.
ASME Y14.41-2012 is based upon ASME Y14.5-2009 symbols and definition methods, such as Geometry Dimensioning and Tolerancing (GD&T). Subscribers of International Organization for Standardization (ISO) have the standards ISO 1101 and ISO 16792 for model-based definition.
