In compliance with EURACHEM/CITAC Guide 2 [72] polymer/additive analysis can be considered as a collection of discrete subtasks (Figure 1.3), each consisting of a number of unit processes, themselves composed of modules containing routine unit operations. The unit processes are characterised as being separated by natural dividing lines at which work can be interrupted and the test portion can be stored without detriment before the next step. [Pg.16]

The process to estimate the uncertainty as described in the GUM as well as in the EURACHEM/CITAC guide is divided in four steps. [Pg.253]

Once we know an estimate of the measurement uncertainty another problem comes up. How do we handle those uncertainties in compliance assessment The ideas described here are taken from a EURACHEM/CITAC- Guide. [Pg.267]

Sabe and Rauret [33] and Drolc et al. [34], however based upon the Eurachem/ CITAC guide on traceability [3]. In their examples, all authors take into account specific steps or influences in the analytical procedure which can lead to a broken chain of comparisons, such as sampling and sample treatment or preparation steps. Some authors have reported on uncertainties associated with sampling in particular [35,36]. [Pg.751]

Accreditation is a formal recognition that a laboratory is competent to carry out specific (types of) calibrations or tests [2]. After the use of validated and standardized methods, the introduction and use of appropriate IQC procedures and the participation in PT schemes, accreditation to ISO/IEC 17025 is the fourth basic principle related to laboratory QA in general [4]. Guidelines on the implementation of ISO/IEC 17025, including the estimation of MU (see also Section 8.2.2), are published in the literature and by official accreditation bodies such as Eurachem, CITAC, EA, Eurolab, and ILAC (see Table 1) [2,60, 80, 81,110]. It is worthwile to mention that accreditation, just like participance in PT schemes, does not necessarily indicate good performance of the laboratory [108]. [Pg.782]

Abstract Based on the new draft of the EURACHEM/CITAC Guide Traceability in Chemical Measurement , this publication describes how traceability can be achieved for chemical measurements using a linear calibration function. Traceability can be accomplished without larger expenditure, if the measurement is calibrated on the basis of appropriate reference standards and the linear regression employed is selected and...
