Crushed stone and sand from porous rock. Technical specifications

This standard establishes the technical specifications for porous rock fragments and sand. It outlines the requirements for quality, testing methods, and classification criteria. The document provides detailed guidelines on the physical and mechanical properties that materials must meet. It also includes procedures for sampling and analysis to ensure compliance with defined standards. The standard aims to ensure uniformity in the production and application of these materials across various industries. It covers aspects such as particle size distribution, density, and resistance to wear. Additionally, it defines the conditions under which materials are tested and the acceptable limits for deviations. This standard serves as a reference for manufacturers, suppliers, and users to ensure product consistency and reliability.
