Sand, crushed stone & gravel certification in Kazakhstan

Products covered by this service

• Construction sand
• Crushed stone and gravel from dense rock
• Concrete and mortar aggregates

Why conformity assessment matters

Impurities, weak particles and inconsistent grading affect concrete performance. We establish the assessment route for sand and crushed stone separately under Order No. 435. Road-use aggregates also need a check of the relevant regulatory scope.

Certificate or declaration: the document depends on the specific product and applicable regulation.

Properties considered in the assessment

• Grading and fines content
• Strength, crushing and frost resistance
• Radiological properties under applicable requirements

These are programme-selection considerations. Required tests depend on the specific product, standard and conformity assessment scheme.

Standards to consider

Examples are shown with their scope. A catalogue listing does not make a standard mandatory for every product in this group. The applicable edition and regulatory link are checked for each request.
