ASTM C117 Materials Finer than 75-μm (No. 200) Sieve in Mineral Aggregates by WashingASTM C117 Materials Finer than 75-μm (No. 200) Sieve in Mineral Aggregates by Washing: Eurolabs Laboratory Testing Service
ASTM C117, Materials Finer than 75 μm (No. 200) Sieve in Mineral Aggregates by Washing, is a standard test method for determining the amount of materials finer than 75 μm (No. 200) sieve in mineral aggregates. This testing service is crucial in ensuring that mineral aggregates meet specific requirements for construction projects, as excessive fine particles can affect the performance and durability of concrete.
The standard is published by ASTM International (formerly known as American Society for Testing and Materials), a global standards development organization dedicated to promoting public health and safety through voluntary consensus standards. The standard has undergone several revisions over the years, with the current version being C117-19.
Legal and Regulatory Framework
ASTM C117 is part of a broader regulatory framework that governs the use of mineral aggregates in construction projects. In most countries, building codes and regulations require that materials meet specific standards for quality, composition, and performance. Failure to comply with these regulations can result in costly fines, project delays, or even litigation.
The standard is recognized internationally by various organizations, including:
These organizations have adopted ASTM C117 as a basis for their own national standards, ensuring that the testing service meets global requirements.
Standard Development and Evolution
The development of ASTM C117 involves a rigorous process involving experts from industry, academia, and government. The standard is revised periodically to reflect changes in technology, materials science, or regulatory requirements.
The evolution of ASTM C117 highlights the ongoing efforts to improve the accuracy and relevance of testing methods. For instance, revisions in 2019 introduced new procedures for sample preparation, increased the sensitivity of measurement equipment, and provided guidance on data interpretation.
Standard Compliance Requirements
Compliance with ASTM C117 is mandatory for various industries, including:
Regulatory bodies, such as government agencies or industry associations, may also require compliance with this standard. Failure to comply can result in penalties, fines, or project cancellations.
