- Abstract:
- The risks of making decisions on conformity assessment are analyzed using the example of rebar from a large Uzbek manufacturer and a small business. An interlaboratory comparison was organized using the capabilities of an accredited proficiency testing provider for the following indicators: cross-sectional area, yield strength and tensile strength of rebar (GOST 12004). The indicators are measured by a fixed value of steel density - 7850 kg/m³. An analysis of the risks of using the measured and fixed value of rebar density for these indicators is carried out. An improvement of the measurement method, an analysis of the contributions to measurement uncertainty and the value of scatter are proposed. Further prospects for the development of certified reference material for the above indicators are also proposed.
