This document specifies methods for sampling and sample preparation for the determination of the chemical composition of pig irons, cast irons and steels. Methods are specified for both liquid and solid metal.

Abstract

Overview

ISO 14284:2022 - Steel and iron - Sampling and preparation of samples for the determination of chemical composition - defines standardized methods for taking and preparing samples of pig iron, cast iron and steels for chemical analysis. The standard covers both and metal sampling and establishes requirements for sample quality, identification, conservation and arbitration samples to ensure reliable, reproducible chemical composition results.

Key topics and technical requirements

Scope and terminology: Definitions and normative references to establish consistent sampling language.
General requirements: Criteria for sample quality, size, identification, conservation and record-keeping.
Sampling methods:
- From melts - procedures for taking samples directly from liquid metal.
- From products - selecting representative laboratory samples from cast and wrought products.
- Spoon sampling and probe sampling - methods and maintenance for both pig-iron, cast-iron and liquid steel.
Sample preparation:
- Preliminary preparation and production of test samples in the form of chips, fragments, solid blocks, or by remelting.
- Specific preparation for chemical, thermal and physical test methods.
Gas determinations: Special sampling and test‑portion preparation for oxygen, nitrogen and hydrogen analysis.
Product‑specific guidance: Increment sampling for pig-iron consignments; sampling and preparation for cast-iron products, plates, bars, tubes and pipes.
Safety and maintenance: Personal protection, machinery safety, hazardous materials handling and equipment upkeep to secure valid samples and protect personnel.

Practical applications and users

ISO 14284 is essential for organizations involved in metal production, testing and quality assurance:

Steelmakers and foundries - process control, tapping and ladle sampling, alloy verification.
Metallurgical laboratories - preparing representative test portions for chemical, thermal (e.g., combustion, spectrometric) and physical testing.
Quality control and inspection bodies - acceptance testing, consignment checks and arbitration samples.
Procurement and materials engineering - verifying incoming materials against specifications and standards.
Research & development - producing reproducible samples for new alloy development and comparative studies.

Using ISO 14284 helps ensure traceable, representative sampling and consistent sample preparation, reducing analytical variability and disputes over composition.

Related standards

ISO 14284 is used alongside other ISO standards for chemical analysis, metallurgical testing and sampling practice. Laboratories and producers should cross‑reference applicable ISO standards for analytical methods, equipment calibration and safety procedures when implementing this sampling guidance.

Keywords: ISO 14284, sampling and preparation, steel and iron, chemical composition, spoon sampling, probe sampling, pig iron, cast iron, liquid steel, sample preparation, metallurgy, quality control.
