ISO 23247:2026 Adds MIRS Path for Shock Absorbers

On July 14, 2026, ISO released ISO 23247:2026, a standard on performance requirements and test methods for structural damping devices, and the update is notable for manufacturers, testing bodies, procurement teams, and end-use engineering organizations working with shock absorbers. The key change is the introduction of a multi-band impact response spectrum (MIRS) route as an equivalent method for evaluating seismic performance, which may shorten certification cycles by about 40%, while also making access to ISO/IEC 17025-accredited specialized vibration tables a practical requirement.

What the standard change explicitly introduces

According to the provided event information, ISO published ISO 23247:2026 on July 14, 2026 under the title Structural damping devices — Performance requirements and test methods. The standard newly introduces multi-band impact response spectrum, or MIRS, as an equivalent evaluation method for the seismic performance of shock absorbers. Under this route, manufacturers may use MIRS instead of traditional time-history analysis. The provided summary also states that this can reduce certification time by around 40%. At the same time, the MIRS-based path requires the use of specialized vibration tables accredited under ISO/IEC 17025.

Where the operational impact is likely to appear first

For shock absorber manufacturers, the certification workflow becomes the first point of change

From an industry perspective, manufacturers are the most directly affected because the update changes how seismic performance may be demonstrated. The immediate impact is likely to show up in test planning, certification scheduling, and coordination with external laboratories. What deserves closer attention is whether existing product approval timelines, internal validation procedures, and customer commitments were built around traditional time-history analysis and now need to be adjusted to reflect the new optional path.

For accredited laboratories and testing service providers, capability and access may matter more than demand alone

Analysis shows that the requirement for ISO/IEC 17025-accredited specialized vibration tables places testing service providers in a central role. The practical issue is not only technical method adoption, but also whether the required accredited equipment is available for the relevant certification workload. For service providers, the most affected business links are likely to be capacity scheduling, method execution, and documentation support tied to certification submissions.

For procurement and supply chain teams, delivery timing may become a contract issue

Procurement functions, supply chain coordinators, and project delivery teams may be affected because certification timing often influences shipment readiness, product acceptance, and downstream installation schedules. If some suppliers move to the MIRS route while others remain on traditional analysis paths, buyers may need to compare documentation packages, test bases, and expected lead times more closely than before.

For end-use engineering and project owners, equivalence does not remove the need for technical review

End-use enterprises and project-side engineering teams may also need to pay attention because the new route is described as an equivalent evaluation method, not simply a procedural shortcut without conditions. The business impact is likely to appear in technical review, supplier qualification, and acceptance communication. Observably, teams that specify seismic performance requirements may need to confirm how they interpret and review certifications based on MIRS.

What companies should track now

How ISO wording is applied in actual certification practice

Companies should closely track how the standard text is applied in real certification workflows, especially where customers, certification bodies, and testing partners may interpret the new MIRS route differently. The key practical issue is the difference between a standard allowing an approach and the market uniformly accepting it in day-to-day approval processes.

Whether testing resources meet the accreditation condition

The provided information makes one condition clear: the MIRS route requires a specialized vibration table accredited under ISO/IEC 17025. That means supplier qualification and lab selection become immediate operational checks. Manufacturers and sourcing teams should verify in advance whether intended testing partners meet that condition and whether scheduling constraints could offset part of the expected time savings.

How product documentation and customer communication are updated

If a company plans to use MIRS instead of traditional time-history analysis, documentation strategy becomes important. Test reports, technical files, and customer-facing compliance explanations may need to reflect the selected route clearly. This is especially relevant where customers or downstream reviewers are more familiar with legacy analytical approaches.

Which orders, markets, or project stages are most sensitive to cycle-time changes

Analysis shows that the stated reduction of roughly 40% in certification time could matter most in orders with tight delivery windows or projects where approval timing affects installation and commissioning. Companies should identify which current or upcoming business lines are most exposed to certification lead time and prepare internal communication and contingency plans accordingly.

Why this looks more like a directional signal than a finished market outcome

Observably, this update carries a clear operational signal: ISO has opened a formal alternative path for seismic performance evaluation of shock absorbers within ISO 23247:2026. At the same time, it is more appropriate to understand this as a standards-level development whose commercial and technical effects still depend on adoption in testing practice, buyer acceptance, and access to accredited equipment. The presence of a time-saving pathway is significant, but the accreditation requirement means implementation may not be uniform across all participants from the outset.

How the market should read this update for now

The immediate meaning of the release is not that all certification processes will change overnight, but that a new recognized route now exists within an ISO standard and could alter how some manufacturers organize compliance work. From an industry perspective, this is best read as a concrete near-term procedural change with broader implications that still require observation. The most rational current view is to treat it as both an actionable operational update and a longer-term signal about how performance verification methods may evolve in practice.
