Detailed Standards Coverage

ISO 19717:2026 - Model-Free Kinetics for Plastics Characterization

Plastics — Differential scanning calorimetry (DSC) or thermogravimetric analysis (TGA) — Model-free kinetics based on the non-linear incremental isoconversional method

Scope and Purpose: ISO 19717:2026 introduces a model-free approach for analyzing the kinetics of chemical reactions and phase transitions within plastics by leveraging the isoconversional principle. This method operates on the core assumption that the reaction rate at a specific conversion depends exclusively on temperature, irrespective of scan rate—breaking away from conventional kinetic models that require fixed activation energies and explicit reaction schemes.

Key Requirements and Features:

• Applicable to both dynamic and isothermal temperature program measurements via differential scanning calorimetry (DSC) or thermogravimetry (TG)
• Enables determination of conversion-dependent activation energy, supporting complex systems with multiple or competing reactions
• Providing for the prediction of reaction kinetics and conversion behavior outside directly measured temperature regions
• Can extend to other measurement techniques able to produce conversion curves
• Not applicable in the glassy state of polymers

Who Should Implement: This standard is crucial for R&D scientists, polymer engineers, process developers, and QA professionals involved in material characterization, thermal analysis, process design, and product reliability assessment—especially in fields where precision thermal properties are critical.

Practical Implications:

• Enables accurate simulations and predictions of material behavior, vital for process optimization and product design
• Reduces errors common with model-dependent methods where competing processes exist
• Improves reliability of thermal endurance assessments and chemical stability studies

Notable Improvements: This edition formalizes a non-linear, incremental isoconversional analysis and corrects limitations found in previous ISO standards (e.g., ISO 11357-7) that assumed constant activation energies. It places significant focus on real-world complexities, such as overlapping transitions and side reactions.

Key highlights:

• Eliminates the need to pre-select a kinetic model
• Supports conversion-dependent analysis for more accurate predictions
• Broadens applicability to a wider range of polymer systems

ISO 6123-3:2026 - Dimensional and Geometrical Tolerances for Rubber and Plastics Covered Rollers

Rubber or plastics covered rollers — Specifications — Part 3: Dimensional and geometrical tolerances

Scope and Purpose: This comprehensive update, part of the ISO 6123 series, sets forth classes of dimensional and geometrical tolerances for rubber or plastics covered rollers and the test methods for measurement. With the importance of rollers in diverse sectors—printing, textile, paper, packaging, and more—precision in their dimensions and geometry is crucial for seamless operation and product quality.

Key Specifications:

• Defines dimensional tolerances for roller diameter, length-to-diameter ratios, and cover length
• Establishes geometrical tolerances: radial run-out, cylindricity, and crown tolerances
• Covers methodologies for test conditions, specimen preparation, and measurement tools
• References harmonized terminology and test procedures for consistency across global markets

Who Needs to Comply: The standard is essential for roller manufacturers, OEMs, system integrators, and procurement specialists. It also supports industries where rollers are central to production efficiency and downstream product quality, such as packaging, converting, and graphics.

Practical Implementation:

• Enables consistent manufacturing, reduced product rejects, and improved machine compatibility
• Clarifies roles in quality control and incoming inspection
• Facilitates global trade and supplier qualification through a shared language of tolerances and test methods

Improvements Over Previous Editions: ISO 6123-3:2026 replaces ISO 6123-3:1985, updating terms and simplifying the classification of tolerances. This streamlines compliance and helps manufacturers adapt to evolving industry demands for tighter tolerances and more reliable performance.

Key highlights:

• Up-to-date classes and test methods for dimensional accuracy
• Simplified tolerance classifications for easier adoption
• Greater alignment with current manufacturing capabilities and quality expectations

Industry Impact & Compliance

Impacts on Industry: The publication of ISO 19717:2026 and ISO 6123-3:2026 signals a shift toward advanced, data-driven material characterization and globally harmonized production standards. Prospective adopters will benefit by:

• Enhancing material reliability and predictability in critical applications
• Mitigating production losses due to improper tolerances or thermal instability
• Facilitating international trade by certifying compliance to widely recognized benchmarks
• Accelerating product development cycles through rigorous, yet flexible testing protocols

Compliance Considerations:

• Immediate review and update of laboratory and manufacturing SOPs to reflect new methods and tolerances
• Staff training for lab technicians and production engineers on new test procedures
• Third-party certification bodies and internal QA teams should cross-reference latest edition specifications
• Factor in compliance timelines, as major clients may mandate conformity to latest editions and backward compatibility may be limited

Benefits of Adoption:

• Competitive differentiation via assurance of best-in-class process and product quality
• Reduction of risk in specification-based contracts and supply chain relationships
• Simpler, more transparent documentation for audits and regulatory reviews

Risks of Non-Compliance:

• Increased non-conformity rates in products shipped to global markets
• Possible rejection or recall of manufactured parts by downstream partners
• Erosion of trust in material certifications and test data

Technical Insights

Common Requirements Across the Standards:

• Both standards emphasize precise, technically robust measurement and calibration—vital for data integrity in QC and product validation
• Harmonized terminology and procedures with normative references to core ISO documents (such as ISO 472, ISO 1101, ISO 11357-1)
• Importance of proper test specimen conditioning and use of standardized equipment

Implementation Best Practices:

1. Review Instrument Calibration: Ensure DSC, TGA, and measurement instruments are regularly calibrated to the updated specifications.
2. Standardize Conditioning: Adhere to exact conditioning protocols (humidity, temperature) recommended in referenced standards for valid results.
3. Document Test Reports Accurately: Include all data required by the test report sections for regulatory traceability.
4. Engage in Cross-functional Training: Facilitate understanding of the new requirements among lab, production, and quality personnel.
5. Integrate Digital Solutions: Where feasible, automate data capture and analysis for both thermal methods and geometrical measurements.

Testing and Certification Considerations:

• Establish internal and, if appropriate, external audits to verify compliance with updated requirements
• Keep records of test conditions, used equipment, calibration certificates, and test results as required for accreditation or client audits
• Participate in inter-laboratory comparison programs to benchmark accuracy and repeatability
