ISO 20998-2:2013, titled "Measurement and characterization of particles by acoustic methods — Part 2: Guidelines for the use of ultrasonic attenuation spectroscopy for determining particle size distributions in dispersions", provides detailed guidance on measuring particle sizes in liquid suspensions using ultrasonic attenuation spectroscopy. This method is non-destructive, does not require dilution or sample drying, and is ideal for real-time monitoring of fine particles or nanoparticles in liquid media.
This standard is part of a broader series (ISO 20998) focused on ultrasonic techniques, complementing particle sizing efforts in various research and industrial settings.
Modern industries demand highly accurate, non-invasive techniques to assess and control particle size distribution in suspensions, emulsions, and colloids. Traditional techniques like laser diffraction or microscopy often fall short when it comes to real-time or non-transparent samples. ISO 20998 bridges this gap.
Choosing ISO 20998 isn’t just about compliance — it’s about adopting a competitive edge in precision measurement and scientific accuracy.
Implementing ISO 20998:2013 offers both technical and strategic advantages to organizations:
✅ Accurate Particle Size Analysis: Delivers consistent, repeatable measurements across complex fluid systems.
✅ Real-Time Monitoring: Enables in-process control without interrupting production.
✅ Non-Invasive Methodology: No need for sample preparation or alteration — preserving original composition.
✅ High Sensitivity: Detects nano-sized particles, useful in advanced material development and quality control.
✅ Standardized Framework: Promotes harmonized testing procedures across global operations.
Adopting ISO 20998:2013 can yield significant business outcomes, including:
1.Enhanced Product Quality
Maintain tighter control over formulation, texture, and stability — critical for food, pharma, cosmetics, and paint industries.
2.Reduced Operational Risks
Prevents inconsistencies in product performance caused by particle agglomeration or dispersion issues.
3.Regulatory and Market Compliance
Meet international testing standards, essential for export, R&D validation, and third-party quality audits.
4.Brand Credibility and Trust
Gain client and stakeholder confidence by showcasing scientific rigor in your testing protocols.
5.Competitive Differentiation
Position your business as a leader in adopting cutting-edge, non-destructive quality control technologies.
6.Increased Efficiency
Save time and resources with real-time analysis, reducing reliance on external labs or destructive testing methods.
