Directly inspected VIM3 entry4.2, blank indication: indication from a similar phenomenon/body/substance with the quantity of interest assumed absent or not contributing. Cite the specific edition/entry; do not conflate the broader VIM background-indication alternate term with every narrower chemical blank usage.

Entry3.1 is measuring instrument; entry3.2 is measuring system, which may consist of one instrument. Entry2.6 defines a detailed measurement procedure including a model and calculation, with an optional target uncertainty.
Additional verified VIM3 material entries: https://jcgm.bipm.org/vim/en/5.13.html and https://jcgm.bipm.org/vim/en/5.14.html
Entry5.13 defines reference material through property-specific homogeneity, stability and fitness for intended use; note2 distinguishes precision control without an assigned value from calibration/trueness control requiring an assigned value. Entry5.14 defines certified reference material and its documented property values, uncertainties and traceabilities.

Additional verified locator: https://jcgm.bipm.org/vim/en/4.18.html , VIM3 entry 4.18, detection limit. The definition specifies a probability beta of falsely claiming absence at a given probability alpha of falsely claiming presence; note 1 gives IUPAC default values alpha = beta = 0.05. An observed decision threshold and a signal level meeting both error-probability criteria are distinct quantities.
