DOCUMENTS BEFORE DELIVERY
Verify the Documents for Your Exact Equipment Scope
Testing equipment documentation should be checked against the product, model, configuration, destination market and purchasing specification—not assumed from a generic certificate label.
DERUI maintains quality-management, product conformity, calibration and inspection records for applicable equipment. This page identifies the scope shown on each published document. Project-specific files can then be reviewed before quotation or shipment.
- Quality Management
- EMC & LVD
- Calibration Records
- Inspection Documents
- Technical Files
02 · QUALITY MANAGEMENT
ISO 9001 Quality Management System
The certificate identifies DERUI's audited quality-management scope, registration details and validity period. It should be read according to the activity stated on the certificate—not as a product approval for every machine.

04 · DOCUMENT SELECTION
Which Quality Document Does Your Project Need?
A conformity certificate, calibration certificate and inspection record answer different questions. Define the purchasing or audit requirement first so the correct document can be matched to the equipment.
Start with the required evidence—not the document name.
Tell us what your customer, laboratory procedure or destination market must verify.
Use the three paths below to identify the document category. Availability, issuing body, language and delivery timing must be confirmed for the exact model and project.
Product Conformity
Used to review a listed product or model against the directive and standards stated on the document.
- Check the listed model
- Check directive and standard
- Confirm ordered configuration
Calibration Certificate
Records calibration results for identified measuring functions, equipment and a specific calibration date.
- Define parameters and ranges
- Confirm required laboratory
- Check date and recommended interval
Inspection & Project Records
Supports agreed inspection, acceptance or delivery evidence for the supplied system and project scope.
- Define acceptance items
- Confirm report language
- Agree timing before shipment
For an accurate document check, send:
equipment name and model · measuring parameters · destination country · required issuing body or accreditation · document language · required date.
Customer-specific records may contain client, address, serial-number and measurement data. Public examples may therefore be redacted; unredacted project documents are handled according to the agreed supply scope.
05 · PATENTS & INTELLECTUAL PROPERTY
Documented Engineering Intellectual Property

DERUI Trademark Registration
Registration No. 62004215 · Class 9 · Registered October 7, 2022 · Valid through October 6, 2032
English titles are concise reference translations for this page. Patent numbers and the original Chinese records control formal identification. Patent ownership does not replace product conformity, calibration or performance documentation.
06 · PROJECT DOCUMENT REVIEW
Confirm the Required Documents Before Quotation
The correct document set depends on the equipment model, supplied configuration, destination market and your purchasing or audit requirements. Send the scope early so availability and applicability can be reviewed with the machine configuration.
Define the equipment
Provide the equipment name, model, test purpose, voltage and configuration under review.
Define the requirement
List the destination country, directive, standard, accreditation, language and customer document list.
Review the document set
DERUI checks the available conformity, calibration, inspection and delivery records against that scope.
Include these details in your request
- Equipment name and model
- Test method or application
- Voltage and selected options
- Destination country or region
- Required document list
- Language and required date
Attach the purchasing specification or customer checklist when available. This reduces repeated confirmation and helps identify gaps before order placement.
