SZGH CNC Machines Are CE-Certified: Inside The Full EU Compliance Test Report

When European buyers evaluate a Chinese CNC machine tool supplier, the first question is rarely about price — it's about proof. Does this machine actually meet EU safety law, or is the "CE" mark on the product page just a sticker?

For the SZGH series of CNC machining centers manufactured by Shenzhen GuanHong Technology Co., Ltd., that proof exists in the form of three independently issued technical documents from a third-party testing laboratory, Shenzhen SiCT Technology Co., Ltd. Together, they form what the EU calls a Technical Construction File (TCF) — the complete evidentiary basis for the CE marking on 19 SZGH machine models.

This article walks through what's actually inside those reports, in plain language, so that engineers, procurement managers, and compliance officers evaluating SZGH machines know exactly what has been tested, how, and against which standards — without having to read all 186 pages themselves.

The Three Documents That Make Up the CE File

Before getting into the technical detail, it's worth understanding how the three reports relate to each other, because each one covers a different legal requirement under EU law.

All three were issued by Shenzhen SiCT Technology Co., Ltd., an independent testing laboratory, following testing conducted June 22–29, 2026, with the reports dated June 29, 2026. All three explicitly reference each other by report number, which matters: the certificate (XK2606013085C) states plainly that it "is only valid in connection with the test report number XK2606013085E, XK2606013085M" — meaning the certificate cannot be separated from the underlying test data. This is a detail worth knowing, because it's exactly what a diligent European importer or notified body will check first.

Which Machines Are Covered

All three documents cover the same 19 SZGH model numbers under the trademark SZGH:

SZGH-25, SZGH-36J, SZGH-36Y, SZGH-46J, SZGH-46Y, SZGH-46Z, SZGH-56J, SZGH-540, SZGH-540A, SZGH-540B, SZGH-540C, SZGH-540D, SZGH-650, SZGH-650A, SZGH-650B, SZGH-650C, SZGH-650D, SZGH-850, SZGH-T6

Electrically, the certified machines are rated at 380V~ 50/60Hz, 9kW input — standard three-phase industrial power specs that align with both Chinese factory environments and European industrial supply.

Part 1: Machinery Directive (MD) Compliance — Report XK2606013085M

This is the largest of the three documents and the one that speaks most directly to physical operator safety. It's structured in three parts.

Part I – General

This section lays out GuanHong's quality control system: how the company applied for CE consulting through a qualified Chinese certification body (Shenzhen Youbest Testing Technology Co., Ltd.), how incoming parts are inspected against the Technical Construction File, how in-process and pre-shipment inspections are carried out, and how design changes are documented and re-verified. It also contains the formal EC Declaration of Conformity, listing every harmonized standard used to demonstrate compliance with the Machinery Directive (2006/42/EC) and Low Voltage Directive (2014/35/EU):

• EN ISO 12100:2010 — Safety of machinery: general principles for design, risk assessment and risk reduction

• EN ISO 13857:2008 — Safety distances to prevent hazard zones being reached by upper and lower limbs

• EN ISO 13850:2015 — Emergency stop, principles for design

• EN 953:1997+A1:2009 — Guards, general requirements for design and construction

• EN ISO 13849-1:2015 — Safety-related parts of control systems

• EN 1088:1995+A2:2008 — Interlocking devices associated with guards

• EN 60204-1:2018 — Electrical equipment of machines

• EN ISO 16090-1:2022 — Machine tools safety, machining centres

• EN 12417:2016 — Milling machines, transfer machines

Part II – Assessment of Conformity

This is a clause-by-clause audit against every Essential Health and Safety Requirement (EHSR) defined in Annex I of the Machinery Directive. Each requirement — from general safety-integration principles, to control system reliability, to starting/stopping devices, to emergency stop functionality — is evaluated individually and marked Pass or Not Applicable. For example, the report confirms that control devices are "clearly visible and identifiable," that the stop control "has priority over the start controls," and that the machine can be "stored in fumigation wooden case safely and without damage" during transport. Every applicable clause returned a Pass result.

Part III – Standard-Specific Test Reports

This section contains the detailed test data for EN ISO 12100:2010, EN 60204-1:2018, and EN ISO 16090-1:2022, plus a dedicated section for earthing continuity, insulation resistance, and withstand voltage testing — the three electrical safety tests that verify a machine won't create a shock hazard under normal or fault conditions. The report closes with photographic documentation of the physical test unit.

Part 2: EMC Compliance — Report XK2606013085E

Machinery Directive compliance covers physical and control safety. But a CNC machine is also an electrical device that can emit interference or be disrupted by it — which is exactly what the EMC Directive (2014/30/EU) regulates. Report XK2606013085E documents this testing across two categories.

Emissions Testing (Does the machine interfere with other equipment?)

• Disturbance voltage at the mains terminals — conducted emissions measured directly at the power connection

• Radiated disturbances — electromagnetic emissions measured over the air

• Harmonic current emissions — checks that the machine's power draw doesn't distort the electrical grid

• Voltage fluctuations and flicker — verifies the machine doesn't cause visible lighting flicker on shared circuits

Immunity Testing (Can the machine withstand real-world electrical noise?)

• Electrostatic discharge (ESD) immunity — simulates static shock from an operator touching the machine

• Radiated susceptibility — tests resistance to ambient RF interference (e.g., from radios, wireless devices)

• Electrical fast transient/burst immunity — simulates switching noise from nearby equipment

• Surge immunity — simulates lightning-induced or switching-induced voltage spikes

• Conducted susceptibility — tests immunity to noise conducted through power/signal lines

• Voltage dips and short interruptions immunity — verifies the machine tolerates brief power drops without failure

The certificate confirms these tests were run against EN IEC 61000-6-4:2019, EN IEC 61000-6-2:2019, EN IEC 61000-3-2:2019+A1:2021+A2:2024, and EN 61000-3-3:2013+A1:2019+A2:2021 — the current, up-to-date versions of each standard (note the 2024 amendment reference, meaning this isn't a stale certification riding on an outdated standard revision).

Part 3: The Certificate of Conformity — XK2606013085C

The one-page certificate is the document most buyers will actually see first, but it's only meaningful in light of the two reports above. It formally states that the sampled SZGH machine conforms with EMC (2014/30/EU), Machinery (2006/42/EC), and Low Voltage (2014/35/EU) directives, referencing all seven harmonized standards from both underlying reports in one place.

One clause is worth highlighting for buyers doing due diligence: the certificate explicitly states it "does not imply the assessment of the production" — meaning it certifies the tested sample, and ongoing production consistency is the responsibility of GuanHong's internal quality control system (the ISO 9001-aligned QC process documented in Part I of the MD report). This is standard practice across CE self-declaration schemes and is exactly why the quality control section of the MD report matters as much as the pass/fail test data.

Why This Level of Detail Matters for Buyers

A CE mark by itself is a manufacturer's self-declaration — it is not, by default, third-party verified. What elevates SZGH's compliance file is that an independent lab (SiCT) performed the actual testing, documented the methodology, equipment used, and raw results, and cross-referenced every certificate to a specific, retrievable test report number. For a European importer, distributor, or end-user running procurement due diligence, that traceability is the difference between a marketing claim and an auditable technical file — and it's exactly what a market surveillance authority would ask to see if ever questioned.

If you're comparing CNC machining center suppliers and want to verify compliance claims, the questions to ask any manufacturer are simple: Which standards were tested? Who tested them, and are they independent? Can I see the report numbers referenced on the certificate? For the SZGH series, those answers are documented in test reports XK2606013085M and XK2606013085E, and summarized in certificate XK2606013085C — available on request for technical and compliance review.
