Technical files for product families, contract manufacturing and design changes
Models sold under one brand are not automatically covered by a single report. Use intended purpose, product risks, manufacturer responsibilities and the destination market to establish which evidence covers each model.
Questions for your situation
Where should I start when selling a contract-manufactured product under my brand?
Examine how placing the product on the market under your name or brand affects manufacturer obligations under the applicable legislation. Define access to technical documentation, change notification, traceability and nonconformity handling in the manufacturing contract. Verify how a report naming another company relates to your product.
Does testing one model cover the entire product family?
Compare power, materials, software, dimensions, protection and intended uses. Justify which variants the tested sample represents. Critical differences may require further assessment or testing. The report's model identification, marketed product label and component list should be consistent.
Is the added equipment's CE marking sufficient when installing a robot or conveyor?
Examine control, stopping, access and material-transfer interfaces between interconnected equipment. Documents for individual machines may not address the risks of the integrated assembly. Assess the whole arrangement after establishing the integrator's role, intended purpose and applicable legislation.
Can LVD, EMC and RED work share one technical file?
Organise the file around a common product description while identifying applicable legislation separately. Radio functions, electrical characteristics and electromagnetic behaviour raise different assessment questions. A satisfactory test in one area does not establish compliance with every requirement. Check RoHS and chemical obligations for the product as well.
Is any laboratory report sufficient for pressure equipment or ATEX products?
First establish the product's scope, category and conformity assessment route. The test subject, sample and laboratory competence are separate from the notified body's authorised scope where its involvement is required. The ability to issue a test report does not establish authority to certify under a particular module.
Are construction product, EN 1090 and ISO 3834 documents interchangeable?
Distinguish product performance, factory production control and quality requirements for welding. Intended use and the applicable technical basis determine the construction product's assessment route. An ISO 3834 assessment alone does not authorise CE marking of every construction product.
Should I consider TSE, TSEK or HYB for my product?
Establish whether the request concerns a product or a service facility. Assessment against a product standard or criterion differs from assessment of a service facility's adequacy. Obtain the exact document name and intended use from the customer, then check the relevant TSE service and application scope.
Can a medical device retain its old file after a software or intended-purpose change?
Assess the effect on intended purpose, risk classification, performance and existing conformity assessment. A new marketing claim about use may also matter. Update design-change records, risk management and verification evidence, and follow the relevant body's change procedure when required.
Practical example
A fictional manufacturer plans two power options and a remotely controlled version of a machine. Engineers map common parts, different components and use scenarios. They revisit risks arising from the control change and establish which models existing reports represent. Additional evidence is then requested because of technical differences, rather than a marketing name change alone.
This is a fictional example, not an actual client case or conformity decision.
Share the subject, organisation or product, target market, current evidence and target date. The team can then separate consultancy, official fees, independent evaluation and realistic timing.
