Quality & Certifications
Quality, Calibration and Certification: What Each Proves
A company certificate, a laboratory accreditation and a product test result answer different questions. Check who was assessed, which activity was covered and whether the scope matches your test.
Visible proof
Recognised seals. Precisely defined scope.
The marks make independent certification and validation immediately recognisable. The evidence sections below explain what each status covers—and what it does not.
Independent proof of the certified quality-management system.
Independent proof of the certified environmental-management system.
Recognisable proof for the explicitly validated conformance-test-system scope.
Important: a seal is a trust signal, not an unlimited claim. The current certificate, validated configuration, legal entity and published scope remain authoritative.
Evidence architecture
One assurance chain. Four different forms of proof.
Certification, accreditation, validation and test evidence are complementary. They are not interchangeable. Each has a different owner, scope and decision value.
Management-system certification
Managed quality
ISO 9001Audited processes for consistently planning, executing, reviewing and improving organisational work.
Boundary: the certified entity and covered sites.Management-system certification
Managed environmental impact
ISO 14001A structured environmental management system with defined responsibilities and continual improvement.
Boundary: the certified entity and management system.Laboratory accreditation
Calibration competence
DIN EN ISO/IEC 17025Technical competence and impartiality for the calibration activities listed in the accredited scope.
Boundary: the named laboratory, quantities and ranges.Test-system validation
Defined conformance scope
CharIN CCTSValidation of a named test-system setup for specific charging-system application profiles.
Boundary: the validated setup, profile and release.The rule: never extend a claim beyond the entity, activity, profile, configuration or validity documented by its evidence.
Management systems
Certified management systems govern how we work.
comemso states certification to ISO 9001 and ISO 14001 by DEKRA Certification GmbH. These certifications concern organisational management systems. They are not individual product certificates.
Quality management
Creates a controlled framework for responsibilities, processes, documentation, review and continual improvement.
- Defined process ownership
- Controlled documentation and change
- Corrective action and improvement
Environmental management
Provides a systematic basis for managing environmental aspects, objectives, responsibilities and improvement measures.
- Environmental objectives and controls
- Responsibilities and monitoring
- Continual improvement of performance
Accredited calibration competence
Measurement confidence for e-mobility applications.
DIN EN ISO/IEC 17025 establishes requirements for the competence, impartiality and consistent operation of testing and calibration laboratories. The published documents name comemso eMobility Services GmbH, Calibration Services, in Ostfildern as the holder of accreditation D-K-22210-01-00.
For a manufacturer of measurement and test systems, in-house metrology expertise strengthens the connection between product development, measurement accuracy and traceable calibration services. It also gives customers, including testing and calibration laboratories, one explicit evidence route for the published scope.
The accredited scope covers defined electrical calibration quantities. Published ranges include DC-voltage measurement and source values up to 1,000 V and DC-current measurement up to 500 A, supporting high-power charging measurement applications.
Reference
Use a traceable reference.
Calibrate
Record the as-found result.
Adjust
Adjust if supported.
Verify
Check the defined criteria.
Record
Preserve the evidence.
Release
Release the verified result.
Service scope, evidence and ownership remain explicit.
The published documents are dated 30 March 2023. The current DAkkS database and valid scope remain authoritative.
Conformance test-system validation
Validated for defined CharIN CCTS application profiles.
The current CharIN register lists comemso as a validated test-system vendor for Charging System Basic and Charging System Extended DC EVSE (electric vehicle supply equipment, or charging station) application profiles.
Charging System Basic
Validated CCTS scope based on the applicable CharIN specification and umbrella document for Basic DC EVSE.
Charging System Extended
Validated CCTS scope based on the applicable CharIN specification and umbrella document for Extended DC EVSE.
Scope remains explicit: CharIN validation supports conformance testing and development testing with the validated system. It does not turn every product, configuration or customer DUT into a certified object.
Traceability by design
From requirement to result, context stays attached.
A result becomes technical evidence only when the objective, configuration, test logic, measurement status and report remain attributable.
Test objective
DUT (device under test), role, risk and engineering decision.
Controlled configuration
Hardware, interface, software and options.
Versioned test logic
Standard, edition, profile and Test Library.
Traceable measurement
Calibration status, channels, timing and limits.
Reproducible evidence
Result, deviation, context and report object.

| Evidence | What it supports | What it does not prove | Primary route |
|---|---|---|---|
| ISO 9001 / ISO 14001 certificate | An audited management system for the certified entity and sites. | That a specific product passes a technical standard or customer test. | Current certificate and validity |
| ISO/IEC 17025 accreditation | Laboratory competence for listed calibration activities and ranges. | Activities outside the accredited scope or conformity of the calibrated product. | Current DAkkS record and scope |
| CharIN CCTS validation | A defined test-system setup and application profile. | Certification of a customer EV, EVSE or unrelated test-system scope. | Current CharIN register |
| Calibration certificate | Unit-specific measurement results and metrological traceability. | Protocol correctness, interoperability or full product conformity. | Certificate for the named instrument |
| Test report | Results for the named DUT, configuration, conditions and test logic. | Equivalent results for another release, configuration or operating condition. | Project or system report |

Quality & Certifications FAQ
The decisive question is always the same: what exactly does the evidence cover?
Which ISO certifications does comemso state?
The public comemso company page states certification to ISO 9001 for quality management and ISO 14001 for environmental management by DEKRA Certification GmbH. Current certificate copies, validity and covered entities should be checked before formal use.
What is the difference between certification and accreditation?
Management-system certification confirms that an organisation operates an audited management system. Laboratory accreditation confirms technical competence for the specific conformity-assessment activities listed in the accredited scope. The terms are not interchangeable.
Which legal entity holds accreditation D-K-22210-01-00?
The published accreditation documents name comemso eMobility Services GmbH, Calibration Services, in Ostfildern as the holder of accreditation D-K-22210-01-00.
What does the published calibration scope include?
The published scope covers electrical calibration quantities and includes DC-voltage measurement and source ranges up to 1,000 V and DC-current measurement ranges up to 500 A. The current DAkkS record and valid annex remain authoritative.
