Machine Safety: ISO 12100, ISO 13849 and SISTEMA
Do the whole machine safety job, not one vendor's part of it: an ISO 12100 risk assessment, guards and interlocks, light curtains with a checked safety distance, the required performance level, a category 3 or 4 design, MTTFd, DCavg and CCF, PL verification in the free SISTEMA tool, validation to ISO 13849-2, IEC 62061 compared, and the technical file the EU Machinery Regulation 2023/1230 expects from 20 January 2027.

What you will learn
Carry out an ISO 12100 risk assessment with machine limits, hazards, risk estimation and the three-step method; choose guards and interlocking devices to ISO 14120 and ISO 14119; calculate light-curtain safety distances to ISO 13855:2024; specify safety functions and determine PLr from the risk graph; choose a category and calculate MTTFd from B10d, DCavg and CCF; verify the PL in SISTEMA and read its report; choose stop categories and compare IEC 62061 with ISO 13849-1; plan and record validation to ISO 13849-2; apply safe drive functions and muting; and assemble the technical documentation and declaration that the EU Machinery Regulation 2023/1230 requires, with the US and UK routes compared.
- Carry out an ISO 12100 risk assessment task by task and apply the three-step method in order
- Choose fixed guards, interlocks and guard locking, and the ISO 14119 device type and coding level
- Calculate light-curtain safety distances to ISO 13855:2024 from measured stopping times
- Write safety functions and set PLr from the risk graph, with a reason for each choice
- Choose a category and work out MTTFd from B10d, T10d, DCavg, CCF and the PL achieved
- Model safety functions in the free SISTEMA tool and read and file its report
- Choose stop categories and drive functions (STO, SS1, SLS) and compare IEC 62061 with ISO 13849-1
- Validate to ISO 13849-2 and assemble the technical file for the EU Machinery Regulation 2023/1230
The course project · about 14 hours
Making an assembly cell safe: risk assessment, safety functions to PL d and e, SISTEMA and validation
Take a clamping and press-fit assembly cell from risk assessment to a validated design: specify six safety functions with their PLr, design the guard-door function in category 3, verify every function's PL in SISTEMA, calculate the light-curtain distance from measured stopping times, and write the validation record and the technical-file index. The sample pack shows each document for a cell built near Turin, Italy.
Sample document pack, 5 documents, filled in for the scenario
- Risk registerRisk assessment register: assembly cell AC1
- SRSSafety requirements specification: assembly cell AC1
- ReportPL verification report: assembly cell AC1 (SISTEMA summary)
- Test reportValidation record: safety functions SF1 to SF6
- RegisterTechnical documentation index and draft EU declaration of conformity

A shareable EDWartens certificate
Finish every module and pass the final assessment, and the optional EDWartens certificate is yours. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up. See it below.
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.

Common questions
Who is this machine safety course for?
Controls, electrical and mechanical design engineers at machine builders and system integrators, plant engineers who buy or modify machines, and maintenance engineers who change guarding. It teaches the whole job in a vendor-neutral way, from risk assessment to the technical file.
Is the course free to learn?
Yes. Every module, the notes, the worked problems, the project and the final assessment are free, and SISTEMA is free from the IFA for commercial, teaching and private use. The certificate is optional.
Does it teach ISO 13849-1:2023 or the 2015 edition?
The 2023 edition, which SISTEMA 3 follows: subsystems, the extended safety requirements specification, the new software clause and the revised way of judging P. The notes point out what changed from 2015, because many machines in service were designed to it.
Do I need SISTEMA or any vendor safety software?
SISTEMA, which runs on Windows (or a Windows virtual machine), and a spreadsheet. No safety PLC or vendor software is needed. Programming Siemens or Allen-Bradley safety controllers is covered by our separate vendor courses; this course gives the requirements those programs must meet.
Is it relevant outside Europe?
Yes. ISO 12100 and ISO 13849-1 are used worldwide, and a module compares the EU route with the US (OSHA, ANSI B11, NFPA 79), the UK, Canada and other regions. In India the OSH Code 2020 sets the employer's duties, and builders in India and the Gulf who export to Europe or the US design to the buyer's market rules.
How long does the Machine Safety: ISO 12100, ISO 13849 and SISTEMA course take?
About 20 hours of video, notes and practice at your own pace, of which about 13.5 hours is video. The optional assembly-cell project takes about 14 hours more.
Does this course make me able to CE-mark a machine or sign off safety?
No. It teaches the principles and structure of the standards and the law in its own words. Real machines are governed by the law where they are used, the current editions of the standards and a competent person's judgement.
What certificate does the Machine Safety: ISO 12100, ISO 13849 and SISTEMA course give?
An EDWartens certificate of completion, issued when you finish the modules and pass the 15-question final at 60 percent, with a number anyone can verify on our site. It is not a TÜV functional safety or CMSE certification and is not affiliated with the IFA, ISO, IEC or Pilz; it covers knowledge that those programmes also expect.
Is the Machine Safety: ISO 12100, ISO 13849 and SISTEMA course free in India, and what does the certificate cost?
Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹559 including GST for this intermediate course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
