Compression load cells; used in truck scales, large platform scales, weighbridges and hopper scales. Ring Torsion load cells; used in high accuracy hoppers, silos, platforms and pallet scales. Spoke Type load cells; used in low profile, high precision application. High forces varying from 1t-500t.
The load plate may be solid or segmented. Segmented load plates adapt to the shape of the pavement to more evenly distribute the load on uneven surfaces. The load plate diameter is typically 300 mm diameter on roads and 450 mm on airports, and the load for road testing is about 40 kN, producing about 567 kPa pressure under the load plate (50 kN ...
Standard provides a programmatic access API to calibration and measurement data on the ECU, access to meta information about this data (from A2L files), functions for controlling the execution of measurement tests and simulation models, and specific mathematical functions. ASAM CDF: Calibration Data Format
Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration. These reference materials are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided.
A certificate of analysis (COA) is a formal laboratory-prepared document that details the results of (and sometimes the specifications and analytical methods for) one or more laboratory analyses, signed—manually or electronically—by an authorized representative of the entity conducting the analyses. This document gives assurances to the ...
Since its establishment, the OIML has developed a number of guidelines to assist its Members, particularly developing nations, to draw up appropriate legislation concerning metrology across all facets of society and guidelines on certification and calibration requirements of new products, particularly where such calibration has a legal impact ...
All analytical procedures should be validated. Identification tests are conducted to ensure the identity of an analyte in a sample through comparison of the sample to a reference standard through methods such as spectrum, chromatographic behavior, and chemical reactivity. [5] Impurity testing can either be a quantitative test or a limit test.
The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...
