Overview
FprEN ISO 10249 (ISO/FDIS 10249:2025) defines the procedures for the preliminary visual examination and preparation of samples of fluid fertilizers prior to physical testing. Published under CEN parallel processing, this second-edition standard replaces ISO 10249:1996 and covers handling of single laboratory samples and the blending and reduction of series of samples representative of a consignment or bulk delivery. The document stresses that physical tests should be carried out as soon as possible because fluid fertilizers are sensitive to time and temperature.
Key topics and technical requirements
- Scope and timing
- Physical examination and tests should be performed promptly after sampling.
- Container conditioning and opening
- Inspect containers for defects or leakage; remove debris from closures and open carefully to avoid evaporation losses.
- Visual examination (solutions and suspensions)
- Record ullage (air-space) as a percentage of container capacity.
- Note surface films, incrustations, clarity, colour, temperature, and consistency (free-flowing or gelled).
- Document phase separation, the volume and nature of phases, and any extraneous matter.
- For suspensions, record the type of settling (soft, hard, or hard‑dry).
- Mixing and homogenization
- Procedures differ for solutions and suspensions:
- Solutions: generally shake or stir unless physical assessment prohibits mixing.
- Suspensions: detailed mixing steps to avoid loss of aqueous phase; hard or hard‑dry settling may make samples unsuitable for re‑incorporation.
- Use pouring between clean, dry, transparent containers to ensure homogeneity and avoid entrained air.
- Procedures differ for solutions and suspensions:
- Blending and reduction
- When multiple increments from a homogeneous product are taken, combine thoroughly, then reduce the aggregate to test samples (allowing at least 5% ullage).
- Labelling and reporting
- Labels must include manufacturer, product description, manufacture date, consignor, consignment size, sampling place/date/sampler name, batch references and a reference to this standard.
- Sample test reports must document results, appearance, settling and mixing procedures, deviations, examiner name and date.
Applications and users
- Quality control and R&D laboratories performing physical tests on fluid fertilizers
- Fertilizer manufacturers, blenders and packers managing consignment sampling
- Regulatory agencies and inspectors verifying product conformity
- Logistics and storage operators who handle bulk fluid fertilizer shipments
- Third‑party testing bodies and auditors
Keywords: fluid fertilizers, sample preparation, visual examination, physical testing, ISO 10249, blending and reduction, suspensions, ullage, settling, labelling.
