ISO 11125-5:2025 – Blast-Cleaning Abrasives: Defective Particles and Microstructure Testing

Preparation of steel substrates before application of paints and related products – Test methods for metallic blast-cleaning abrasives – Part 5: Determination of percentage defective particles and of microstructure

This standard provides critical methods for determining the percentage of defective particles and for evaluating the microstructure of metallic abrasives used in blast-cleaning. These test procedures underpin both quality control and procurement processes by enabling users to assess conformity prior to use. With detailed sampling instructions, measurement routines for shape defects in various particle types (shot, grit, cylindrical, irregular), and explicit guidelines for microstructural analysis, ISO 11125-5:2025 closes a key feedback loop between abrasive manufacturing and end-user quality assurance.

For organizations responsible for surface preparation quality, this standard aids defect reduction, predictive maintenance, and process optimization.

Key highlights:

  • Specifies test methods for assessing defective particles and microstructure in metallic abrasives
  • Supports robust incoming inspection and supplier qualification
  • Integrates easily with other ISO 11125-series test procedures

ISO 19828:2025 – Welding for Aerospace: Visual Inspection of Welds

Welding for aerospace applications – Visual inspection of welds

Representing a significant leap in the standardization of aerospace manufacturing, ISO 19828:2025 establishes the requirements for the visual inspection of welds in metallic materials—including both joints and intermediate inspection points. The standard sets rigorous qualification and certification thresholds for inspection personnel, mandates adequate and documented eyesight standards, and provides guidance on direct and indirect inspection methods (using devices such as borescopes and endoscopes).

Special focus is given to minimum training requirements, revalidation intervals, and when indirect inspection is permissible—addressing the unique challenges of aerospace assembly and maintenance. The standard also covers visual inspection of brazed joints, expanding its applicability. With the revision, requirements for documenting visual aids and inspecting welds with restricted access were strengthened, reflecting advances in both inspection technology and regulatory expectations.

Key highlights:

  • Stipulates visual weld inspection procedures for aerospace and high-spec metallic applications
  • Details personnel qualification, recertification, and documentation standards
  • Addresses both conventional and advanced indirect inspection techniques

Common Themes and Industry Trends

A review of July 2025’s Manufacturing Engineering standards uncovers recurring patterns:

  • Elevated Focus on Surface Preparation: Three of five standards addressed blast-cleaning abrasives (both metallic and non-metallic), signaling a substantial push to harmonize classification, specification, and testing methods. This reflects industry needs to control pre-coating and pre-assembly quality at a deeper level.
  • Integration of Testing and Inspection: The publication of both specification and test method standards in tandem (as seen with ISO 11124 and ISO 11125) underscores a move toward end-to-end process validation.
  • Quality and Qualification in Welding: Welding standards centered on operator qualification, visual inspection rigor, and specialized disciplines like aerospace, a sector where error margins are minimal. Heightened recertification, documentation, and equipment standards point to an industry-wide response to growing complexity and safety expectations.
  • Lifecycle Traceability and Re-Use: Specifications on traceability, lot identification, and defective particle rates show a trend toward improving resource efficiency, reducing audit risk, and enhancing circularity—particularly relevant in high-volume or sustainability-driven industries.
  • Sectoral Cross-Applicability: While initially tailored for steelwork, many of these standards were framed to support both ferrous and non-ferrous materials, indicating an awareness of increasingly diverse manufacturing inputs and processes.

Compliance and Implementation Considerations

Organizations affected by these new and revised standards should consider the following steps:

  1. Gap Analysis: Review current procedures and procurement specifications for alignment with new classification, testing, and documentation requirements.
  2. Resource Training: Ensure that quality personnel and weld inspectors meet revised qualification standards, especially for aerospace applications where periodic recertification may now be mandated.
  3. Supplier Communication: Update incoming inspection routines and supplier contracts to specify conformance with the latest ISO 11124, ISO 11125, and ISO 11126 classifications and test protocols.
  4. Process Updates: Where applicable, enhance traceability systems for abrasives and welds to document compliance, facilitate audits, and anticipate feedback loops between use and specification.
  5. Timeline Consideration: Factor in lead times for requalification of personnel and potential re-tendering of supplies to only those conforming with the updated standards.

For organizations seeking to harmonize quality control across multiple sites or geographies, referencing these standards in internal procedures and training documents can accelerate compliance and reduce the risk of non-conformity during future audits.
