About Bonatar

Forty-five years, still on the same problem.

Bonatar is Herman Tesseur. More than forty-five years in machinery safety, most of it on shuttle systems, AGVs and automated intralogistics, and until 2026 Safety Director at Movu Robotics. I stepped back from full-time practice that year, and that is the point of this practice rather than a footnote to it: I no longer need the next project, so you get the reading I actually believe, not the one that keeps me on the account.

What I actually do

Evidence, not opinions.

CE marking is self-declared for most of this machinery. That means the declaration is only as good as the file behind it, and the file is only as good as the thinking in it. I read what you have built, say plainly where it does not hold, and point at the clause rather than at an opinion.

I do not certify machines — no advisor can. You sign the declaration. What I bring is four decades of having seen how these systems fail, and the work of carrying clients’ positions into the process that decides what “safe enough” will mean next.

Standards I work(ED) to

  • EN ISO 3691-1
  • EN ISO 3691‑4
  • EN ISO 26058-1 (new – under development)
  • EN ISO 12895 (new – under development)
  • EN 528
  • EN 619
  • EN xxx for shuttle systems (new – under development)

How I work

Four things I hold to.

Precise

I name the standard, the clause and the date. “To EN ISO 13849‑1:2023” beats “to the relevant standard” every time.

Plain

Short sentences, active voice, ordinary words. Regulatory subject matter is hard enough without the prose adding to it.

Accountable

I say what I will do and by when, and I never claim an outcome that depends on a notified body.

Unalarming

The stakes are real and do not need amplifying. I state the exposure once, then move to the remedy.

A machine without a TECHNICAL DOCUMENTATION is not on the market. It is exposed.

Send the layout drawing and I will tell you what the machine is, which standards apply, and where the risk actually sits.
