A technical data request is a list of evidence needed to make a defined product, trial or purchasing decision. It is stronger than asking for all certificates because every requested field has an intended user, source and acceptance question.

How do TDS, COA and test reports differ in use?

Document type is part of the evidence. A TDS generally describes a product or grade, a COA records lot-related results, and a test report explains a defined evaluation; the buyer should confirm the actual scope and issuer of every file received.

  • TDS: product-level reference
  • COA: stated batch or lot context
  • Test report: method, sample and result context

Why must units and methods travel with values?

A value is not self-explanatory. Diameter in mm, tensile strength in kg or lb and linear density in dtex or denier describe different fields, and a comparison can be misleading if the source unit or method disappears during transcription.

  • Retain original unit and precision
  • Name the method or supplier procedure
  • Record sample conditioning when provided

How does MFE handle supplied website data?

MFE reviewed the supplied 2026 workbook and published 139 parameter rows across 8 PE braided-line series. The site preserves the provided values, flags questionable rows and states that final construction, tolerance and test method require project confirmation.

  • No silent correction of source data
  • No supplier company name carried into the page
  • No raw-yarn claim inferred from a finished-line table

What makes a data request efficient?

An efficient request is prioritised by decision. In our experience, identifying must-have, useful and optional fields reduces document noise and helps the reviewer see immediately which missing item blocks a sample, quotation or approval.

  • Name the decision and reviewer
  • Prioritise fields by consequence
  • Track received, pending and not-applicable status
