American ASTM Certification

A Brief Introduction to ASTM Certification in USA

ASTM is the abbreviation of American Association of Materials and Tests, and its predecessor is the International Association of Materials Testing. The first IATM meeting was held in Europe in 1882, at which a working committee was formed. In 1902, at the fifth annual meeting of the International Association for Materials Testing, the American Branch was declared officially independent. Now let's talk about ASTM authentication numbering method.

The ASTM standard numbering form is:

Standard code + alphabetic classification code + standard serial number + year + standard English name.

Example: ASTM A331M-95 (1996) Standard Specification for Cold-Made Alloy Steel Bars

Explain:

1. The metric unit standard with the letter M after the standard serial number and the English unit standard without the letter M.

2. The time in parentheses after the establishment of a fixed number of years shall be the time for the examination and approval of the standards.

3.a.b.c.... Indicates the revised edition.

4. The alphabetical classification code is:

A - Ferrous Metals

B - Nonferrous metals (copper, aluminium, powder metallurgical materials, conductors, etc.)

C - Cement, Ceramics, Concrete and Masonry Materials

D - Other Materials (Petroleum Products, Fuels, Low Strength Plastics, etc.)

E - Miscellaneous (Metal Chemical Analysis, Fire Resistance Tests, Nondestructive Tests, Statistical Methods, etc.)

F - Special Use Materials (Electronic Materials, Shock-proof Materials, Surgical Materials, etc.)

G-Corrosion, Degradation and Degradation of Materials

ASTM Publishing Standards

According to ASTM publications, in 1997, ASTM formulated 350 new standards, revised 1698 standards and carried out 2681 standardization activities. From these figures, we can see that activities are frequent and fruitful. ASTM standards are now divided into 15 categories (Sections), which contain different volumes. Volumes are published. There are 73 volumes and more than 10,000 standards. They are published in the form of ASTM standard yearbook. The classifications, volumes and standard numbers of the 1999 standard Yearbook are as follows:

Category I Iron and Steel Products

Category II Non-ferrous Metals

Category III Testing Methods and Analytical Programs for Metal Materials

Category IV Construction Materials

Category 5: Petroleum products, lubricants and fossil fuels

Category VI Paints, Related Coatings and Aromatic Compounds

Category 7 Textiles and Materials

Category 8 Plastics

Category 9 Rubber

Category 10 Electrical insulators and electronic products

Category 11 Water and environmental technologies

Category 12 Nuclear and Solar Energy

Category 13 Medical equipment and services

Category 14 Instruments and general test methods

Category 15 General industrial products, special chemicals and consumable materials
