WHAT MAKES US DIFFERENT
Standards
Discipline × Standard matrix — EN, IEC, NFPA, ASHRAE, ASME, API, KIWA, BS, UL, IEEE, NEMA. Standards-flexible engineering, applied to your location and regulator.
Your customer’s location, regulator and preference dictate the standards. We know all the major families, and when each applies.
The matrix — discipline × standard family
For each engineering discipline we run, here is the family of international standards we can apply. Customers tell us their regulatory framework; we build the project to match.

Specific codes — fuel storage example
The single most common point of confusion is the fuel tank standard. Customers often think there is “one right answer” — there is not. The answer depends on where the tank is installed and which regulator must accept it.
| Code | Scope | Region |
|---|---|---|
| EN 12285-1 / -2 / -3 | Workshop-fabricated steel tanks (underground, above-ground, non-cylindrical) | EU |
| EN 13160 | Leak-detection systems (Class I-IV) for double-walled tank monitoring | EU |
| BRL SIKB 7800 / BRL-K903 | Installer certification for fuel & chemical tank installations (NL Activiteitenbesluit) | NL / EU |
| KIWA BRL-K744/04 | Steel non-stationary (mobile / portable) tank containers — atmospheric, up to 20 m³ | NL / EU |
| KIWA BRL-K514 | Above-ground steel tank — structural + corrosion certification | NL / EU |
| KIWA BRL-K756 | Vertical steel tank | NL / EU |
| KIWA BRL-K636 | Overfill prevention devices | NL / EU |
| KIWA BRL-K21002 / K21009 | Polyethylene & thermoplastic tank certifications | NL / EU |
| BS 799-5 | Oil burning equipment — storage tanks (1100 L+ stationary) | UK |
| UL 142 | Steel above-ground tanks for flammable / combustible liquids | US |
| UL 2085 | Protected above-ground tanks — 2-hour fire rating | US |
| API 650 | Welded tanks for oil storage — large (>5,000 bbl), field-fabricated | Global oil & gas |
| API 620 | Low-pressure storage tanks (including cryogenic) | Oil & gas |
| NFPA 30 / 37 / 110 Ch.7 | US flammable-liquid code + stationary engine + EPSS fuel system | US |
| STANAG 3609 | NATO single-fuel concept (F-34 / F-35 — defence) | Military / oil & gas adjacency |

Region quick-picks
When your customer is in one of these regions, this is the typical standards package we apply.
Europe (EU + UK)

Out of scope (deliberately)
To stay focused and not over-promise, two areas are explicitly outside our matrix:
- Cyber security (ICS / NIST 800-82 / IEC 62443 / NERC CIP / ISO 27001). This is a separate specialism. We engage a certified ICS security firm as a partner when the customer needs it.
- Fire suppression design. We coordinate with a Fire Protection Engineer (FPE); we do not design suppression systems ourselves. The line between “power system fire safety” (ours — detection, alarm, segregation, fuel safety) and “suppression system” (FPE’s) is clean and documented.
