Detailed Standards Coverage

ISO 10993-7:2026 - Residuals from Ethylene Oxide Sterilization

Biological evaluation of medical devices — Part 7: Ethylene oxide sterilization residuals

This latest edition of ISO 10993-7 targets manufacturers utilizing ethylene oxide (EO) as a sterilant for medical devices. The standard establishes rigorous allowable limits (AL) for residual EO and ethylene chlorohydrin (ECH), ensuring device safety before release. Comprehensive procedures for measurement, product categorization based on exposure duration, and validated test methods are included, complemented by extensive annexes that provide decision-making flowcharts and risk assessment pathways.

Key requirements dictate batch release protocols, validated dissipation curves, and special considerations for devices using alternative materials or lacking patient contact. Notably, this revision advances risk assessment techniques, introduces subpopulation-specific exposure limits, and provides expanded guidance for product release and change management.

Industries affected include medical device manufacturers, sterilization service providers, quality managers, and regulatory affairs specialists responsible for device release.

Key highlights:

• Specific allowable limits for EO and ECH tailored to device exposure duration and patient populations
• Enhanced measurement and test validation methods, including sampling and extraction protocols
• New risk-based approach for setting and justifying residual limits

ISO 10322:2026 - Ophthalmic Optics: Semi-Finished Blanks

Ophthalmic optics — Semi-finished blanks

ISO 10322:2026 brings together a comprehensive set of requirements for the optical and geometric properties of semi-finished lens blanks used in eyewear manufacturing. The standard classifies blanks by type (single-surface-power, multifocal, power-variation), establishing stringent tolerances for surface power, cylindrical power, thickness, and segment geometry. It further specifies uniformity zones, marking, labeling, and critical quality criteria for packaging.

The revised edition harmonizes with the latest developments in lens technology and manufacturing, making it essential for ophthalmic optics manufacturers, lens designers, and quality assurance teams.

Key highlights:

• Unified classification system by finished surface, not only intended use
• Updated tolerances and measurement methods for modern lens designs (including power-variation and multifocal blanks)
• New marking and packaging requirements supporting traceability and end-user quality

EN ISO 22367:2026 - Risk Management for Medical Laboratories

Medical laboratories - Application of risk management to medical laboratories (ISO 22367:2026)

EN ISO 22367:2026 is a foundational guide for medical laboratories in implementing systematic risk management. Building on ISO 15189 and ISO 31000, it details the identification, estimation, evaluation, control, and monitoring of patient, personnel, and process risks throughout pre-, intra-, and post-examination phases. The document emphasizes proactive and reactive risk strategies, organizational roles, and documentation, without prescribing fixed risk acceptability thresholds.

This standard is indispensable for laboratory managers, clinical quality coordinators, and organizations seeking accreditation or demonstrating compliance with international best practices.

Key highlights:

• Comprehensive risk management process for all laboratory services, including data transmission and technical operations
• Clarifies responsibilities, required competencies, and documentation protocols for risk management
• Offers in-depth annexes on risk analysis tools, benefit-risk evaluation, and real-world risk scenarios

ISO 10993-6:2026 - Local Effects After Implantation

Biological evaluation of medical devices — Part 6: Tests for local effects after implantation

This fourth edition of ISO 10993-6 sets forth updated requirements for preclinical tests that evaluate local tissue response after implantation of medical devices or their components. Enriched with new definitions, guidance for sample preparation, control selection, and histopathological assessment, the standard incorporates advances for animal model selection, test duration, and response evaluation.

Applicable to all medical devices that breach skin or mucosal barriers (from absorbable materials to complex tissue-engineered products), this standard is critical for R&D scientists, preclinical testing labs, and regulatory submission teams.

Key highlights:

• Expanded terminology and sample preparation guidelines (including use of compositionally representative coupons)
• Extra protocols for peripheral nerve tissue and new assessment scoring systems
• Alignment with modern expectations for animal welfare and comprehensive macroscopic/microscopic evaluation
