Functional Safety Standards x Systems Coverage Matrix

Intelligence report, industrialcorp.org catalog. All numbers computed 2026-08-05 from fseventsall.jsonl (15,375 events) + fseventsbatch2.jsonl (377 events) = 15,752 events, plus a live fetch of the sitemap index and all 528 child sitemaps (527,744 URLs, of which 28,065 are event pages). Source data: /Users/zacharylukasiewicz/industrialcorpstrategy/content/corpusstats.json.

1. Shape of the matrix

• 15,752 events, all 30 minutes (7,876 content hours), single category functional-safety.
• 112 unique standards total. 80 of them carry system tags and form the matrix; the other 32 standards live only in the 752-event enriched set that has no system tag (see Section 5).
• 99 unique systems.
• The tagged matrix is 80 standards x 99 systems = 7,920 possible cells. 3,143 cells are non-zero (39.7% fill); 4,777 cells are zero.
• Depth is deliberately flat: every non-zero cell contains exactly 4 or 5 events (2,428 cells at 5, 715 cells at 4). Coverage differences between standards are therefore entirely about breadth (how many systems a standard is paired with), never depth.

2. The matrix, condensed by tier

Standards fall into clean breadth tiers. Events-per-standard tracks breadth almost exactly (roughly 5 events per covered system, minus a few 4-event cells).

System-side, breadth ranks the same way:

3. Densely covered combinations

• The 12 universal-core standards x all 99 systems account for 1,188 of the 3,143 non-zero cells and roughly 5,630 events - more than a third of the catalog. Any system, from SCARA robots to unmanned surface vessels, has IEC 61508 (all three parts), IEC 62443, EMC, AI-safety (ISO/IEC TR 5469, ISO/IEC 42001), and the four analysis methods (HAZOP, FMEA/FMEDA, FTA, SIL determination).
• Manipulator-class systems are the saturated block: all 18 fixed-manipulator systems carry 42 standards each, including the full machinery stack (ISO 12100 through ISO 13849, ISO 14119/14120/13857) and the full robot stack (ISO 10218-1/-2, ISO/TS 15066, R15.06, RIA TR R15.306/R15.606). Cobots x ISO 10218-1 = 5 events, Cobots x ISO/TS 15066 = 5 events.
• Pharmacy and Laboratory Automation Robots are the single deepest rows (48 standards, 240 events) because they are the only systems that get both the industrial machinery stack and the six-standard medical stack.
• The humanoid family is near-saturated. Direct answer to the ISO 13849 question: yes - ISO 13849-1 x Humanoid Robots = 5 events, ISO 13849-2 x Humanoid Robots = 5, and the same 5+5 holds for Bipedal, Wheeled, Legged Quadruped, and Mobile Manipulators. Humanoids also carry ISO 10218-1/-2, ISO/TS 15066, ISO 13482, UL 3300, UL 4600, and the EU Machinery Regulation - 47 standards in total, 235 events per humanoid system, and "humanoid robots" appears in 705 event titles.

4. Top gaps (zero cells worth knowing about)

Ranked by practitioner impact:

1. Humanoids x ANSI/RIA R15.08 = 0. R15.08 (Industrial Mobile Robots) covers exactly 16 systems - the classic AMR/AGV family plus Mobile Manipulators - but none of the four humanoid systems (Humanoid, Bipedal, Wheeled Humanoid, Legged Quadruped). The same 16-system list applies to ISO 3691-4, UL 3100, and B56.5. Mobile Manipulators made the cut; walking robots did not. This is the highest-value zero cell in the matrix: R15.08's applicability to humanoids is an open question in the standards landscape, and the catalog is silent on the pairing.
2. Humanoids x automotive-derived autonomy standards = 0. ISO 21448 (SOTIF), ISO 21434, and ISO 26262 pair with only 5 systems (Autonomous Trucks, Shuttles, Robotaxis, Last-Mile and Sidewalk Delivery Robots). Humanoid AI-safety coverage instead routes through ISO/IEC TR 5469 and ISO/IEC 42001 (5 events each). Practitioners borrowing SOTIF methodology for humanoid perception systems find no bridge content.
3. Patient-Handling Robots x ISO 13482 = 0. ISO 13482 is the personal-care-robot standard whose scope includes person carriers, yet Patient-Handling Robots get only the 19-standard medical stack. Meanwhile ISO 13482 does pair with Humanoids, Exoskeletons, and even Explosive Ordnance Disposal Robots.
4. Medical robots x machinery stack = 0. Surgical, Rehabilitation, Powered Prosthetics, and Patient-Handling Robots (19 standards each) have no ISO 12100, no ISO 13849, no CE Marking pairing - the catalog routes them exclusively through IEC 60601-1 / 62304 / 14971 / 13485 / 80601-2-77/-78. Hospital Logistics Robots, one door down the corridor, carry 46 standards including the full machinery stack.
5. Marine is the thinnest family. ROVs, AUVs, and Unmanned Surface Vessels have only the 12 universal-core standards - no marine-specific safety standard exists anywhere in the 112. 60 events per marine system, all generic.
6. Aerial autonomy misses UL 4600. UL 4600 (Autonomous Products) covers 37 systems, all ground-based; Inspection, Delivery, and Cargo Drones and eVTOL Aircraft are excluded. Outdoor drones sit at 16 standards (universal core + SORA + ISO 21384-3 + MIL-STD-882E for some); only Indoor Warehouse Drones (40 standards) inherit the machinery stack.
7. Rail is method-only beyond EN 5012x. Autonomous Trains, Railway Inspection, and Track Maintenance Robots (16 standards each) get the EN 50126/50128/50129/50657 set plus universal core - no ISO 13849, no protective-device standards, despite track-maintenance machines being machinery in practice.
8. ISO 13849's own 24-system blind spot. The 13849 pair misses all road AVs, all rail, all marine, all outdoor drones, all four medical-robot systems, plus Planetary Rovers, Space Robots, Nuclear Decommissioning Robots, and Robotic Process Skids. Defensible for aircraft; debatable for Patient-Handling Robots and Track Maintenance Robots.

5. The disconnected 752

The enriched batch-2-style set (752 events, no system tag, no audience tag, format "Live webinar") carries 32 standards that appear nowhere in the tagged matrix, concentrated in automotive and autonomy: UL 4600 & Autonomous Systems (46 events), ISO 26262 (44), Functional Safety Foundations (40), ISO 10218 (31), ISO 13849 Machinery Safety (30), R15.06 (30), ISO/PAS 8800 (27), plus ISO 21448, ISO 21434, ISO 26262-11, V-Model, FTA, and AI/ML tracks at 25 each. This is real depth (a 44-event ISO 26262 track) that the matrix cannot see because the events name no system. It also duplicates tagged-side themes under different labels (two ISO 13849 naming variants, three UL 4600 variants), which splits topical authority.

6. What the gaps mean for practitioners

• For anyone in the industrial core - fixed manipulators, cobots, warehouse automation, humanoids - the catalog answers "which standard applies to my machine" for essentially every plausible pairing: 42-48 standards per system, 5 events per pairing. The flat 4-5-event depth means each pairing gets an introduction in up to 31 formats, but no pairing gets a multi-part deep series; a practitioner who has consumed the intro has nowhere deeper to go inside the catalog.
• The humanoid gaps mirror the real standards landscape: no dedicated humanoid safety standard exists, and R15.08's applicability to legged platforms is genuinely unsettled. But that is precisely why the zero cell matters - content that explicitly addresses "R15.08 and humanoids" or "SOTIF methods for humanoid perception" would answer a question the catalog currently leaves open. With 705 event titles already containing "humanoid," such additions would extend an existing strength of the catalog rather than open a new topic.
• The medical/machinery divide is the most practically dangerous gap. A hospital deploying patient-handling or rehabilitation robots faces both the medical-device route and, in the EU, machinery obligations; the catalog implies a clean either/or that does not exist in practice. Bridging content (ISO 13849 for medical robots, MDR-vs-Machinery-Regulation boundary) would fill a real practitioner need, not just a matrix cell.
• Marine, rail, and outdoor-drone practitioners get methods, not applications: HAZOP and FMEA events exist for their systems, but nothing that maps their sector standard (or its absence) to the system. These families have the thinnest coverage in the catalog - the 12-standard marine rows are the floor of the matrix - and they are the most exposed gap in it.
• Site context: the 15,752-event catalog sits inside 28,065 live event URLs and a 527,744-URL site that is 93.6% profile pages (494,161). The matrix is the topical spine of the content strategy; its gaps are the roadmap.
