ASTM Standards Specifications

 

Standards specifications of ASTM are to be discussed here. ASTM International, formerly known as American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Some 12,575 ASTM voluntary consensus standards operate globally.

 

ASTM Headquarters

The organization’s headquarters is in West Conshohocken, Pennsylvania, about 5 mi (8.0 km) northwest of Philadelphia. Founded in 1902 as the American Section of the International Association for Testing Materials (see also International Organization for Standardization), ASTM International predates other standards organizations such as the IEC (1906), DIN (1917), ANSI (1918), AFNOR (1926), and ISO (1947).

In previous passage, we discussed the significance of ASTM standards.  ASTM Material Specifications is the center of discuss in the upcoming passage. Stay with us.

The TEAM PROJECT

TEAM is the abbreviation for Testing and Assessment of Marble and limestone. The use of natural stone as facade cladding has been shown to have much lower life cycle costs and they are more environmentally friendly than comparable products of concrete, glass, and steel.

 

Increased Maintenance Costs

Promoting the use of natural stone has therefore a great positive impact on the environment. However, the number of occurrences of bowing and expansion of marble and limestone panels has led to increased maintenance costs, significant safety risk, and negative publicity. The lack of knowledge of a solution to the problem of bowing marble has a large negative effect on the entire stone trade. In response, short-sighted and less durable construction solutions are used as an alternative, adding to the decreasing export figures and numbers of employees within the stone sector.

 

Urgent Need to Develop a Direct Test Method

The TEAM (TEAM=TEsting and Assessment of Marble and limestone) project addresses a problem with marble types, from several European countries, that display bowing on facades in both cold and warm climates. There is, therefore a need to develop harmonized European standards for differentiating between marble that is susceptible to bowing and marble that is not. Resolution No. 013, in May 1999 taken by the European Committee for Standardization (CEN), Technical Committee (TC) 246 Natural Stone states the urgent needs “to develop a direct test method of the bowing risk for marble cladding products.”

 

Laboratory Research to Make Guidelines

Research both in the laboratory and the field were performed on a large number of different stone types from different countries and used in different climates. This gave the explanation of degradation mechanisms and led to the determination of the critical influencing factors. Two tests methods, including precision statements: one for bowing and one for thermal and moisture irreversible expansion have been prepared for submission to CEN TC 246. Repair techniques based on the use of surface coating and impregnation systems has been tested at laboratory and in the field. Positive side effects including increased durability and easier cleaning have been observed. Guidelines for production and product control have been proposed, and an instruction for stone sampling and description has been developed.
