To understand what is being shown
Start with these questions: how is the product or material identified exactly? What is its stated purpose? Which market does the documentation concern? These simple questions prevent ten minutes of talking about different things under the same trade name.
Add a fourth if there is a sample on the table: is this a raw material, a prototype or the finished product? The answer changes how you interpret what you see. An example under development can be fascinating without all its performance characteristics being validated or a commercial offering being ready for every application.
To follow a document’s trail
Ask which batch or sample the report describes, who issued it and where it can be read in full. If a certification is mentioned, ask about its scope. The distinction published by ENAC helps remind us that accreditation and management-system certification address different questions.
One practical question is: “Which part of this claim is established by that document?” It requires the promise to be connected with the evidence, without assuming in advance that everything is either false or true. If the answer concerns another formulation, a facility or an earlier year, note that difference.
To assess a scientific claim
If a study is mentioned, ask for the reference and what it actually investigated. Was it a substance or a finished product? In which population or model? What outcome was measured? You do not need to debate the whole methodology in an aisle; you can retrieve the work afterwards and read it calmly.
Avoid turning the conversation into a personal medical consultation. A fair does not necessarily provide the setting or information needed for a healthcare decision. These questions aim to clarify evidence and its limits, not to obtain a recommendation for use or a route to purchasing restricted substances.
To understand how changes are managed
Ask what happens if the composition, supplier or specification changes. Are documents updated? Is the version identified? Who responds to an incident? These questions help explain the organisation behind the product and often reveal more than asking for a promise that nothing will ever go wrong.
You can copy these questions into a note and print it from your browser. Leave room beside each answer for a link, date and outstanding question. At the end of the visit, choose what deserves another check. A good list does not turn commercial answers into guarantees; it turns a brief conversation into a starting point you can revisit.
Take this with you
Ask about identity, scope and references. Also record what has not been answered: that blank space points towards the next check.
Sources you can open
The source may be in its original language. English publication does not change the jurisdiction or date discussed.
