🏗️ ASME STP-SA-030-2009 was prepared by independent consultant Paul K. Gines and sponsored by the ASME Safety Codes and Standards and the ASME Standards Technology, LLC (ASME ST-LLC). The report systematically compares thirteen Automated Storage and Retrieval System (ASRS) documents issued by the Fédération Européenne de la Manutention (FEM) against the U.S. ASME B30.13 (Storage/Retrieval Machines and Associated Equipment) specification. The consumer activity present in the North American market creates the need for guidelines that facilitate the safe design, maintenance, and operation of ASRS and their storage/retrieval machines; this report provides a cross-standard perspective to serve that need.
💡 The report’s purpose is not to declare a winner but to lay out the systematic differences between the FEM and ASME systems, feeding input into ASME’s ongoing effort to keep its code and standard products technically relevant.
1. Report Structure and the Compared Documents 📌
The report’s body is organized chapter by chapter around each FEM document: each chapter first describes the specification content of the corresponding FEM document, then analyzes its relationship and differences with ASME B30.13. The thirteen FEM documents under comparison cover the full chain from terminology through design, safety, and performance data:

| FEM 9.832 |
Calculation principles — tolerances, deformations, clearances (small-parts warehouse) |
Small-parts warehouse special case |
| FEM 9.851 |
Performance data — cycle times |
B30.13 does not cover cycle times |
| FEM 9.871 |
Logbook for S/R machines and transfer devices |
Maintenance-record requirements differ |
| FEM 9.881 |
Project planning data for drive selection |
Drive-selection method differs |
⚠️ The FEM 9 series separates design, safety, performance data, and acceptance into independent documents — far finer-grained than ASME B30.13. Teams unfamiliar with both systems risk “cross-referencing” errors; always use the system mandated by the project specification.
2. Analysis of the Main Difference Dimensions 🔧
Chapter 15 of the report lists specifically the “B30.13 inclusions not covered in the reviewed FEM specifications,” and Chapter 16 gives a summary of results. From the chapter-by-chapter comparison, several key difference dimensions emerge:
- Terminology and definitions: FEM 9.001/9.101 establish an independent, complete S/R-machine terminology dictionary, whereas B30.13 relies on the shared ASME B30 series vocabulary; the two define concepts such as “storage/retrieval machine,” “stacker,” and “transfer device” somewhat differently.
- Structural design criteria: FEM 9.311 gives systematic calculation rules and load combinations for S/R-machine steel structures (masts, crossbeams, runway supports); B30.13 leans toward safety requirements and overall limits, with structural detail frequently deferred to engineering judgment or the manufacturer’s standard.
- Safety-rule granularity: FEM 9.754 provides dedicated, detailed safety rules for automatic mini-load S/R machines; B30.13 covers general S/R-machine safety, with less fine subdivision by machine type.
- Performance and reliability metrics: FEM 9.221 (reliability and availability) and 9.851 (cycle times) supply a quantitative performance指标体系 absent from the B30.13 body.
- Tolerances, deformations, clearances: FEM 9.831/9.832 give concrete tolerance and deformation calculation methods for high-bay and small-parts warehouses, ensuring geometrical compatibility between machine and racking.
🚨 An automated high-bay warehouse is a multi-discipline coupled system: the tolerances and deformations of the machine, racking, runway, and civil foundation must be controlled together. Designing to one standard without checking the other’s requirements can cause interferences or inability to operate.

For engineering teams delivering high-bay warehouse projects in both China/North America and other markets, the report can be used to build a “dual-standard difference matrix,” explicitly stating in the project specification which system governs and which clauses are supplemented by the other — satisfying local regulatory demands while keeping global consistency and maintainability.
4. Principal Conclusions 📊
- ✅ FEM is finer-grained, ASME is more consolidated: the FEM 9 series is split by subject with broad coverage and detailed clauses; B30.13 sits within the ASME B30 lifting and material-handling series and focuses on safety and fundamental requirements.
- ✅ Performance metrics are the main gap: reliability/availability (9.221) and cycle times (9.851) as quantitative performance requirements are unique to FEM and not systematically covered by B30.13.
- ✅ Safety rules have different emphases: FEM 9.754’s mini-load-specific safety rules are highly granular, whereas B30.13 provides a general safety framework covering the whole S/R-machine category.
- ✅ Input for code harmonization: the report serves as reference for ASME to later absorb reasonable FEM practices (such as performance metrics and the tolerance system) into revisions of B30.13.
5. Frequently Asked Questions ❓
❓ Q: Which system — FEM or ASME — fits my high-bay warehouse project better?
A: It depends on location, contract, and regulatory requirements. In Europe and FEM-adopting regions, the FEM 9 series is the de facto mainstream; in North America, ASME B30.13 is the most widely referenced S/R-machine standard. Export projects often need to satisfy both in parallel.
❓ Q: Is B30.13 simpler or less demanding than FEM?
A: The difference is not simply higher vs. lower — the two reflect different design philosophies. ASME B30.13 uses a “general requirements + safety focus” consolidated structure, while FEM subdivides by subject and includes extensive performance and tolerance detail. Both require professional engineering judgment.
❓ Q: Where should S/R-machine reliability and cycle-time data be referenced?
A: If the contract calls for quantitative performance metrics (e.g., availability, rated cycle time), they should be established using the FEM 9.221/9.851 framework together with the manufacturer’s guaranteed values; ASME B30.13 does not provide such a metric system in its body.
🔍 Q: What is this report’s significance for the ASME code system?
A: As an ASME ST-LLC safety and technology publication (STP-SA series), it provides a cross-standard comparison basis for the continuous revision of B30.13, helping ASME decide whether to adopt FEM practices such as reliability and tolerance frameworks to maintain technical relevance.
