Tests for general properties of aggregates - Part 1: Methods for sampling

This European Standard specifies methods for obtaining samples of aggregates from deliveries preparation and processing plants including stocks. The aim of sampling is to obtain a bulk sample that is representative of the average properties of the batch. The methods specified in this standard are also suitable for obtaining sampling increments which may be tested separately. Methods to be used for sample reduction are also given.

Prüfverfahren für allgemeine Eigenschaften von Gesteinskörnungen - Teil 1: Probenahmeverfahren

Diese Europäische Norm legt Verfahren zur Entnahme von Proben aus Gesteinskörnungen aus Lieferungen sowie Aufbereitungs- und Bearbeitungsanlagen, einschließlich Vorratslagern fest. Das Ziel der Probeentnahme ist, eine Sammelprobe zu erhalten, die für die durchschnittlichen Eigenschaften eines Loses repräsentativ ist. Die in dieser Norm festgelegten Verfahren eignen sich auch zur Entnahme von Einzelproben, die einzeln geprüft werden können. Verfahren, die bei der Probeneinengung anzuwenden sind, sind ebenfalls enthalten.

Essais pour déterminer les propriétés générales des granulats - Partie 1: Méthodes d'échantillonnage

La présente norme européenne prescrit des méthodes permettant de prélever des échantillons de granulats, qu'ils proviennent de livraisons, d'installations de préparation et de traitement y compris des stocks. L'objectif de l'échantillonnage est d'obtenir un échantillon global qui soit représentatif des propriétés moyennes du lot. Les méthodes prescrites dans la présente norme conviennent également pour obtenir des prélèvements à qualifier séparément. Sontégalement données des méthodes de réduction des échantillons.

Overview

EN 932-1:1996 (CEN) - Tests for general properties of aggregates - Part 1: Methods for sampling - defines accepted procedures for obtaining representative samples of aggregates. The standard covers sampling from deliveries, preparation and processing plants, and stockpiles with the objective of producing a bulk sample representative of the average properties of a batch. It also describes how to obtain sampling increments and gives methods for sample reduction so laboratory test portions can be prepared reliably.

Key Topics

• Scope of sampling locations: deliveries, processing plants, stockpiles and other typical aggregate sources.
• Representative bulk sample: principles and goals to ensure the sample reflects the batch’s average properties.
• Sampling increments: procedures for taking increments that can be treated and tested individually.
• Sample reduction methods: guidance for reducing bulk samples to laboratory-sized test portions while maintaining representativeness.
• Applicability: intended for use where reliable test results on aggregate properties are required for quality control and conformity assessment.

(Note: EN 932-1 specifies methods and principles rather than prescriptive numerical test outcomes. Consult the full standard for procedural detail.)

Applications

EN 932-1 is used wherever accurate aggregate testing depends on correct sample collection and preparation. Typical practical uses include:

• Quality control at quarries, pits and processing plants to ensure outgoing shipments reflect declared properties.
• Sampling incoming materials on construction sites and ready-mix plants to verify supplier compliance.
• Routine laboratory testing where consistent sample reduction procedures are prerequisite to particle-size analysis, mechanical or durability tests.
• Procurement and compliance checks by contractors, material suppliers, testing laboratories and public authorities overseeing road, concrete and asphalt works.

Adopting standardized sampling reduces variability in test results, supports reliable conformity assessment, and improves traceability between field and laboratory measurements.

Related Standards

EN 932-1 is the first part of the EN 932 series addressing general properties of aggregates. For complete assessment workflows, it is normally used alongside other EN standards that specify specific test methods and material requirements for aggregates and construction materials.

By following EN 932-1 sampling methods, organizations improve the accuracy of aggregate testing, support quality assurance, and help demonstrate compliance with European aggregate testing practices.
