The American Society for Testing and Materials International ASTMfounded inis a not-for-profit organization that provides a global forum for the development and publication of voluntary consensus standards for materials, products, systems, and services.
Natural Stone Institute – Which ASTM Standards Are Relevant To Natural Stone
Over 30, individuals from nations are the members of ASTM International, who are producers, users, consumers, and general interest parties such as government representatives and academicians.
Committees are established which focus on and have jurisdiction over standards for different designations, such as Dimensional Stone Committee C18 or Cement Committee C These asm are made up of several subcommittees which are tasked to develop and discuss individual segments within the committee’s jurisdiction. For example, one subcommittee may deal with the development of standards dealing with Test Methods of Dimensional Stone, d1528 another with Anchorage Components and Systems for Natural Stone.
These committees meet on a regular basis to discuss and present information for each new or existing standard. The entire membership of ASTM International votes on whether a standard is suitably developed and researched before it is forwarded for final approval.
Negative votes cast during the balloting process are fully considered before forwarding. Companies, agencies, and individuals use ASTM standards.
Gillis Quarries Ltd. – Codes & Standards
Buyers and sellers of materials, products, and services include these standards in contracts; engineers, scientists, architects, and designers use them in their work; government agencies reference them in codes and regulations; and many others refer to them for performance information. ASTM International is recognized globally and continues to review and develop new standards needed in a wide range of materials.
In today’s building environment, the emphasis is on safe, permanent, low maintenance products, of which stone leads the list in the minds of architects, designers, and consumers worldwide. Without a consistent, realistic set of standards and testing procedures for stone products, the stone industry as a whole would be in disarray.
The standards that have been developed and set in place astj these products are important tools to help protect end users, individual companies, and the industry from negative effects related to product failures. Materials standards help to prevent the use of stone products for unsuitable applications. For instance, without the minimum standards for Abrasion Resistance adtm Stone Subjected to Foot Traffic ASTM Cit would be more likely that very soft, easily damaged materials would be installed in commercial applications.
This may cause the owner to incur additional cost for repair and maintenance, and negatively affect the reputation of the stone industry as a whole.
These standards also serve as benchmarks for quality limits of products. If a stone with a below-minimum flexural strength is used for a lintel, c15528 it may be more likely to fail, thus causing damage and possible injury. Interior or exterior flooring or paving with an inadequate slip resistance level will more likely cause slipping accidents in public or private projects. As stone industry professionals, it is our task to apply the correct standards to materials at appropriate times in order to keep the stone industry strong and to remain a reliable source of quality products.
Most architectural specifications require that stone meet certain specified ASTM or other testing standards before it will be accepted for use. Some products on the market today have not been tested for quality standards that are required for certain projects. The required testing should be reviewed and, if test results are not available for the stone product, then testing should be performed by the quarry or representative company as required.
Some quarries and their representatives do not embrace this idea, because their products can be marketed to homeowners and residential projects without the need to perform testing.
It is up to our adtm to know how to identify these products and make sure to request the required material data needed. Testing ashm stone can be performed by other companies in the event that required test data is not available. Independent labs can perform the appropriate tests and provide the information in a well organized, professional report.
It is important to know when a certain test is not required for a product. For example, a test for Slip Resistance would not be necessary for stone used in a vertical application, which will never receive foot traffic. Some examples are not as easily established. For instance, what are the needs for testing a stone to be used for interior flooring in a commercial application where the stone is installed over a raised floor deck subject to deflection, and will be subject to traffic from pedestrians and cleaning carts weighing 1, pounds?
These are all physical requirements of the stone product during everyday use. Be aware of the requirements of performance that will be placed on the stone at the time of installation, and in the future.
If a stone has proven not to perform for a particular use, then avoid marketing it for that use.
