When a sample adds value

A sample is particularly relevant when dimensions, materials, performance, interfaces, finish or packaging cannot be fully established from drawings, specifications or a quotation. It may be a complete first unit, a component, material sample, prototype, interface part, electronic module or packaging trial.

Not every product requires the same type of sample. For large or unique components, a representative detail or mock-up may be more practical than a complete unit.

First establish what the sample must demonstrate

We determine in advance which questions the sample must answer. Possible inspection points include:

1. Dimensions and proportions.
2. Stated material and visible material build-up.
3. Colour, sheen, texture and visible finish.
4. Construction, joints and hardware.
5. Movement, operation or other testable functions.
6. Connection to other components.
7. Packaging and protection.

Where possible, an inspection point must be linked to a drawing, specification, code, physical reference item or another identifiable standard within the project.

Approve, correct or resubmit

The report makes clear which points comply, which differ and which could not yet be established. You then decide whether the sample is approved, amended subject to conditions or must be resubmitted.

Corrections are not communicated only verbally. The amended version must be reflected in the final drawing, specification, contract schedule or approved reference sample.

The approved sample as a production reference

An approved sample can be used as a reference for production and subsequent quality control. If so, record which physical unit or digital documentation forms the reference, where it is kept and which deviation margins have been agreed.

A good sample does not guarantee that every production unit will be identical. Appropriate production or final inspections therefore remain relevant.

What you receive

1. An agreed list of sample criteria.
2. An assessment against the available project references.
3. Photographs, measurements and findings within the scope.
4. An overview of approved points, discrepancies and open questions.
5. A written basis for correction, production and subsequent inspection.

Frequently asked questions

Does the sample need to be sent to the Netherlands? Not always. Some characteristics can be assessed and recorded on site. Physical shipment may be necessary for fit, material properties, interface testing or an independent technical assessment.

Who gives final approval for the sample? You, or the engineer, technical specialist or other expert you appoint. CONSOO & CO reports the findings and ensures that the decision is recorded in writing.

Is a factory photograph sufficient for sample inspection? A photograph can form part of the documentation, but it does not automatically show dimensions, material, function, construction or colour accurately. Its usefulness depends on the inspection point.

Discuss your trade enquiry — determine which choices must be made visible before production.
