Описание (английский):

This international standard specifies a method for the measurement of the static angle of repose of solid fertilizers. The method is applicable to free flowing fertilizers and is suitable for measuring static angles of repose greater than 20 °C; the method is not suitable for materials which contain a large proportion of particles exceeding 5 mm in diameter.

Overview

EN 12047:1996 - "Solid fertilizers - Measurement of static angle of repose (ISO 8398:1989 modified)" is a CEN standard that describes a laboratory method to determine the static angle of repose of solid fertilizers. The procedure is intended for free-flowing fertilizers and sets applicability limits for particle size and measured angles. The standard is based on ISO 8398:1989 (modified) and is commonly referenced in fertilizer quality control and materials-handling specifications.

Key Topics

Scope and applicability

Method applies to free-flowing solid fertilizers.
Not suitable for materials containing a large proportion of particles exceeding 5 mm diameter.
The published scope states suitability for measuring static angles of repose greater than 20 °C (as written in the source text); users should verify the intended unit or check national errata or the original ISO text for clarification.

Reference to ISO 8398

Procedure is derived from and modified relative to ISO 8398:1989.

Measurement focus

Standard defines how to determine the static angle of repose, a key indicator of flowability and bulk behaviour of granular fertilizers.

Limitations

Intended only for free-flowing products; not suitable for coarse or highly cohesive materials.

Applications

Quality control and product specification

Use the angle-of-repose measurement to monitor batch-to-batch consistency and to support product claims about flow characteristics.

Storage and handling design

Inform hopper, silo and conveyor design by providing a parameter related to heap stability and flow.

Packaging and logistics

Assess potential handling issues (bridging, arching) during filling, transport and discharge operations.

R&D and formulation

Guide formulation changes and granulation processes to achieve desired flow properties.

Laboratories and certification

Adopted by testing labs, fertilizer producers, and inspection bodies for routine testing and compliance checks.

Related Standards

ISO 8398:1989 - original international method on which EN 12047 is based (modified in the EN version).

National adoptions and later revisions: check current CEN listings and national standards bodies for updated versions, national annexes, or errata.

Note: For implementation, consult the full EN 12047:1996 text or the relevant national adoption to ensure procedural details, apparatus specifications and any national modifications are followed.
