ISO 19595:2017 PDF Download

ISO 19595:2017 is a standard that defines the properties and requirements of natural aggregates that are used in the production of concrete. The standard is applicable to aggregates that have a particle density of more than 2,000 kg/m3, as determined by the ISO 22965 standard.

The standard includes a general requirement that natural aggregates should not release any harmful substances that exceed the maximum permitted levels specified for the material, or those specified in the national regulations of the intended place of use. However, national provisions can also specify additional or different requirements, and these should be documented in a national annex or project specification.

It is important to note that ISO 19595:2017 does not specify the requirements for the end use of aggregates in concrete. These requirements are defined in ISO 22965 standard.
