Stationary source emissions — Greenhouse gases — Part 2: Ongoing quality control of automated measuring systems

ISO 14385:2014 specifies procedures for establishing quality assurance for automated measuring systems (AMS) installed on industrial plants for the determination of the concentration of greenhouse gases in flue and waste gas and other flue gas parameters. ISO 14385:2014 specifies the following: ? a procedure to maintain and demonstrate the required quality of the measurement results during the normal operation of an AMS, by checking that the zero and span characteristics are consistent with those determined using the relevant procedure in ISO 14956; ? a procedure for the annual surveillance tests (AST) of the AMS in order to evaluate a) that it functions correctly and its performance remains valid and b) that its calibration function and variability remain as previously determined. ISO 14385:2014 is designed to be used after the AMS has been accepted according to the procedures specified in ISO 14956. ISO 14385:2014 is restricted to quality assurance (QA) of the AMS and does not include QA of the data collection and recording system of the plant.

Emisije nepremičnih virov - Toplogredni plini - 2. del: Zagotavljanje kakovosti avtomatskih merilnih sistemov

Ta dokument določa postopke za vzpostavitev ravni zagotavljanja kakovosti avtomatskih merilnih sistemov (AMS) v industrijskih obratih za določanje koncentracije toplogrednih plinov v dimovodih ter odpadnih plinov in drugih parametrov dimnega plina. Ta del standarda ISO 14385 vključuje: – postopek za vzdrževanje in dokazovanje zahtevane kakovosti rezultatov meritev med normalnim obratovanjem avtomatskega merilnega sistema s preverjanjem, ali so ničelne in razponske značilnosti skladne s tistimi, določenimi z ustreznim postopkom v standardu ISO 14956; – postopek za letne nadzorne preskuse (AST) avtomatskega merilnega sistema, s katerimi se oceni, a) ali pravilno deluje in podaja veljavne rezultate ter b) ali sta njegova funkcija kalibracije in variabilnost še vedno v stanju, kot je bilo predhodno ugotovljeno. Ta del standarda ISO 14385 je zasnovan tako, da se uporablja po tem, ko je avtomatski merilni sistem potrjen in sprejet v skladu s postopki, določenimi v standardu ISO 14956. Ta del standarda ISO 14385 je omejen na zagotavljanje kakovosti avtomatskih merilnih sistemov in ne vključuje zagotavljanja kakovosti zbirke podatkov in sistema za beleženje v obratu.

Introduction
The measurement of greenhouse gas emissions (carbon dioxide, nitrous oxide, methane) in a framework
of emission trading requires an equal and known quality of data.
This part of ISO 14385 describes the quality assurance procedures for calibration and ongoing quality
control needed to ensure that automated measuring systems (AMS) installed to measure emissions
of greenhouse gases to air are capable of meeting the uncertainty requirements on measured values
specified by legislation, competent authorities, or in an emission trade scheme.
