Overview
EN ISO 21663:2020 (CEN adoption) specifies instrumental methods for the determination of total carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) in solid recovered fuels (SRF). The standard covers both micro (milligram test portions) and macro (gram test portions) instrumental apparatus and procedures, and applies to results expressed on a dry matter basis for concentrations of C > 0.1%, N > 0.1%, H > 0.1% and S > 0.05%. It replaces EN 15407:2011 and provides guidance on sample handling, calibration, analysis and reporting.
Key Topics and Requirements
- Scope and applicability: Total C, H, N and S determination in SRF using instrumental combustion methods; micro vs macro methods depending on test portion size.
- Principle: Combustion/oxidation of a known mass and conversion of combustion products (CO2, H2O, N2/NOx, SOx) to species measurable by detectors.
- Sample handling: Requirements for laboratory sample, general analysis sample and test portion preparation; emphasis on careful preparation for micro-methods.
- Calibration and reagents: Use of suitable calibration standards and carrier gases; calibration procedures and verification to ensure measurement traceability.
- Apparatus and procedure: Instrumental analyzers for elemental analysis; procedural steps for sample introduction, combustion, product treatment and detection.
- Performance characteristics: Precision, coefficient of variation and robustness testing data are addressed; laboratories should follow these performance criteria.
- Safety and reporting: Safety instructions for instrument operation and required contents of the test report.
Practical Applications
- Quality control and fuel specification: Characterising SRF for combustion performance, calorific value estimation and feedstock specification.
- Regulatory compliance and environmental reporting: Supporting emissions calculations and compliance with permits by providing reliable C/H/N/S data.
- Waste-to-energy and cement industries: Input fuel characterisation for process control, burner tuning and slag/ash management.
- Laboratory accreditation and inter-lab comparisons: Standardised method for routine elemental analysis in accredited testing labs.
Who should use this standard
- Analytical and environmental laboratories performing SRF testing
- SRF producers and fuel suppliers for product specification
- Waste‑to‑energy and industrial combustion facilities for fuel characterisation
- Regulatory bodies and conformity assessment organizations

Introduction
The determination of total content of carbon, hydrogen, nitrogen and sulfur is usually performed
using instrumental methods. Depending on the amount of test portion used two different types of
instrumental methods can be used: micro methods require few milligrams of sample; macro methods
use grams of sample. Micro methods require a very careful preparation of the test sample for Solid
Recovered Fuel (SRF) analysis.

The EN ISO 21663:2020 standard provides a comprehensive framework for the determination of essential elements-carbon (C), hydrogen (H), nitrogen (N), and sulfur (S)-in solid recovered fuels, utilizing instrumental methods. The scope of this standard is explicitly defined, focusing on measuring the total content of these elements, which are critical not only for the assessment of fuel quality but also for compliance with environmental regulations. One of the key strengths of this standard is its flexibility in methodological approach, as it accommodates both micro and macro instrumental apparatus based on the volume of the test specimen. This dual applicability enhances its usability across various laboratory settings, ensuring that laboratories can select the appropriate method that aligns with the sample size and concentration levels. Moreover, the specified concentrations-C greater than 0.1%, N greater than 0.1%, H greater than 0.1%, and S greater than 0.05% on a dry matter basis-provide clear, quantifiable thresholds that ensure accuracy and reliability in testing. The relevance of EN ISO 21663:2020 is profound, as it plays a crucial role in the solid recovered fuels sector, which is growing in importance due to increasing sustainability efforts and regulatory demands. By standardizing the methods for determining key elemental content, this standard directly supports compliance with environmental standards and promotes responsible management of recovered fuels. Overall, EN ISO 21663:2020 stands out as a vital standard that is well-aligned with industry needs, offering robust methods that enhance the precision of elemental analysis in solid recovered fuels while also striving for environmental sustainability.
EN ISO 21663:2020 표준 문서는 고형 회수 연료에서 탄소(C), 수소(H), 질소(N), 황(S)의 총 함량을 기기 분석 방법으로 측정하는 절차를 규명합니다. 이 표준의 범위는 해상도 있는 실험적 접근법을 통해 연료의 화학적 성분을 정확하게 파악할 수 있도록 설계되었습니다. 이标准의 강점 중 하나는 미세 및 대형 기기 분석 기구를 사용하는 유연성입니다. 테스트 샘플의 양에 따라 적합한 분석 장비를 선택할 수 있어 다양한 실험 환경 및 필요 사항에 맞추어 효율적으로 적용할 수 있습니다. 또한, 고형 회수 연료의 탄소 함량이 0.1%를 초과할 경우, 질소 및 수소 또한 동일한 기준을 적용하여 측정할 수 있다는 점에서 실험의 신뢰성을 높이고 있습니다. EN ISO 21663:2020은 고형 연료의 품질 평가 및 환경적 영향 분석과 관련된 산업에서 중요한 역할을 합니다. 이 표준은 연료의 화학적 조성을 명확히 함으로써, 에너지 생산과 관련된 관리 및 규정을 충족시키는 데 필수적입니다. 특히, 재활용 연료의 사용 증가와 함께 해당 기준의 중요성은 더욱 커지고 있습니다. 따라서 SIST EN ISO 21663:2021 문서는 고형 회수 연료의 분석 과정에서 신뢰할 수 있고 일관된 결과를 제공하는 도구로서, 귀중한 자료로 자리 잡고 있습니다. 이는 고형 회수 연료 관련 업계의 과학적 연구 증진과 품질 관리에 새로운 기틀을 마련하는 데 기여할 것입니다.
SIST EN ISO 21663:2021は、固形再生燃料における炭素（C）、水素（H）、窒素（N）、および硫黄（S）の含有量を定量するための標準化文書です。この標準は、機器分析法を用いて、固形再生燃料中のこれらの元素の総含量を測定するための手法を明確に規定しています。 この文書の範囲は非常に具体的で、固形再生燃料の検査における有用性を示しています。特に、テスト試料の量に応じてマイクロまたはマクロの機器を使用する方法が示されており、非常に柔軟性があります。これは、さまざまな環境や条件での適用が可能であり、業界内での広範な利用が期待できます。 標準の強みは、測定対象の元素の低濃度（C > 0.1%、N > 0.1%、H > 0.1%、S > 0.05%）に対応している点です。これにより、固形再生燃料の品質評価や管理が一層確実になることが期待され、環境保護や持続可能なエネルギー利用の観点からも重要な位置を占めています。 また、この標準の関連性は、固形再生燃料の市場が拡大している現状においてますます高まっています。エネルギー効率や環境影響の観点から、固形再生燃料の分析方法としての重要性が増しています。この標準化文書は、業界全体での透明性を確保し、信頼性の高い測定結果を提供するための基盤となるでしょう。
