Full title and description

ISO 10249:1996 — Fluid fertilizers — Preliminary visual examination and preparation of samples for physical testing. This International Standard specifies how to carry out a preliminary visual examination of fluid-fertilizer samples received and how to prepare test samples by blending and reduction from a series of samples representative of a consignment.

Abstract

Specifies a procedure for the preliminary visual examination of a single sample as received and a procedure for preparing a test sample by blending and reduction of a series of samples representative of a consignment of fluid fertilizer. The standard is intended to ensure that samples submitted for physical testing are representative and appropriately prepared.

General information

• Status: Published (international standard; reviewed/confirmed in 2019 — currently shown as to be revised under ISO review processes).
• Publication date: 1996-12 (Edition 1, December 1996).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.080 (Fertilizers).
• Edition / version: Edition 1, 1996.
• Number of pages: 5 pages (printed standard).

Scope

Defines methods for the preliminary visual examination of fluid-fertilizer samples as received and the preparation of representative test samples for subsequent physical testing (for example: blending and sample size reduction from multiple subsamples to form a single test sample). The procedures are intended to provide reproducible, representative samples for physical property tests used in quality control and regulatory assessment.

Key topics and requirements

• Preliminary visual examination of a single sample as received (appearance, phase separation, foreign matter indications).
• Procedures for preparing a test sample from a series of subsamples representing a consignment (blending and reduction techniques).
• Requirements to ensure representativeness of the test portion for physical testing of fluid fertilizers.

Typical use and users

Used by chemical and agricultural testing laboratories, fertilizer manufacturers and packers, quality-control personnel, regulatory and inspection bodies, and standards developers who need to prepare representative samples of fluid fertilizers for physical property testing and quality assessment. National standards bodies and testing labs commonly adopt ISO 10249 for harmonized sample preparation procedures.

Related standards

Adopted/translated and published in regional/national collections as EN ISO 10249 (1999) and corresponding national versions (for example NF EN ISO 10249 and DIN/UNE adoptions). Related fertilizer sampling and test-method standards from ISO/TC 134 and regional technical committees cover chemical analysis and other physical test methods for fertilizers.

Q: What does it cover?

A: It covers the preliminary visual check of samples as received and the method for preparing a test sample by blending and reduction from a series of subsamples representative of a consignment, to be used for subsequent physical tests.

Q: Who typically uses it?

A: Fertilizer testing laboratories, manufacturers and packers, quality control teams, inspection and regulatory authorities, and standards organizations adopting the ISO procedure for consistent sample preparation.

Q: Is it current or superseded?

A: The 1996 edition is published and was last reviewed/confirmed in 2019; ISO records indicate the document has been subject to review and may be scheduled for revision under ISO’s review process. Users should check their national/corporate standards catalogue for any more recent replacements or related editions.

Q: Is it part of a series?
