Construction products - Assessment of release of dangerous substances - Complement to sampling
This Technical Report covers the specific requirements for sampling construction products to determine the release or emission of dangerous substances in their intended use. It is complementary to existing sampling standards and sampling instruction in product standards or test methods for construction products of CEN product TCs and EOTA committees which fall under the CPD.
The scope of this Technical Report covers all activities related to product sampling, starting with the initial planning of sampling until the delivery and formal transfer of the laboratory sample at the laboratory.
This Technical Report:
- does not deal with sub-sampling in the laboratory as a step towards the preparation of the test portion / test specimen );
- does not deal with the second sampling domain in which a sample is to be taken from the air (emission) or water (release) with which the test portion / test specimen has been in contact;
- does not deal with the statistical testing of a construction product against (legislative) limit values, nor does it deal with the definition of repetitive sampling, suitable for fulfilling requirements with respect to a minimum level of uncertainty in a series of test results.
This Technical Report focuses on obtaining a single sample. Repetitive sampling is outside the scope as the boundary conditions for routine testing against a limit are not yet defined (e.g. the necessary reliability). Despite the fact that repetitive sampling is not covered, the conditions provided in this Technical Report apply for an individual sample, as well as for a sample that is part of a series.
Bauprodukte - Bewertung der Freisetzung von gefährlichen Substanzen - Ergänzung zur Probenahme
Produits de construction - Evaluation de l'émission de substances dangereuses - Complément relatif à l'échantillonnage
Le présent Rapport technique du CEN couvre les exigences spécifiques relatives à l'échantillonnage des produits de construction en vue de déterminer le relargage ou l'émission de substances dangereuses lors de leur utilisation prévue. Il est complémentaire aux normes d'échantillonnage existantes et aux instructions d'échantillonnage contenues dans les normes de produit ou les méthodes d'essai relatives aux produits de construction élaborées par les comités techniques de produits du CEN ou les comités de l'EOTA qui relèvent de la DPC.
Le domaine d'application du présent Rapport technique du CEN couvre toutes les activités liées à l'échantillonnage du produit, depuis la planification initiale de l'échantillonnage jusqu'à la livraison et au transfert formel de l'échantillon au laboratoire.
Le présent Rapport technique du CEN :
- ne traite pas de l'étape de sous-échantillonnage au laboratoire en vue de préparer la prise d'essai ou l'éprouvette ) ;
- ne traite pas du deuxième domaine d'échantillonnage dans lequel un échantillon doit être prélevé dans l'air (émission) ou l'eau (relargage) avec lesquels la prise d'essai ou l'éprouvette a été en contact ;
- ne traite pas des tests statistiques d'un produit de construction par rapport à des valeurs limites (légales) et ne traite pas de la définition d'un échantillonnage répétitif, appropriés pour satisfaire aux exigences relatives au niveau minimal d'incertitude dans une série de résultats d'essai.
Le présent Rapport technique porte principalement sur l'obtention d'un échantillon unique. L'échantillonnage répétitif ne relève pas du domaine d'application car les conditions aux limites pour les essais de routine par rapport à une limite ne sont pas encore définies (par exemple la fiabilité nécessaire). Bien que l'échantillonnage répétitif ne soit pas couvert, les conditions fournies dans le présent Rapport technique s'appliquent aussi bien à un échantillon individuel qu'à un échantillon faisant partie d'une série.
Gradbeni proizvodi - Ocenjevanje sproščanja nevarnih snovi - Dopolnilo k vzorčenju
To tehnično poročilo zajema specifične zahteve za vzorčenje gradbenih proizvodov za ugotavljanje sproščanja ali emisij nevarnih snovi pri njihovi predvideni uporabi. Dopolnjuje obstoječe standarde vzorčenja in navodila za vzorčenje v standardih za proizvode ali preskusne metode za gradbene proizvode odborov za proizvode CEN TC in EOTA, ki spadajo v okvir CPD. Obseg uporabe tega tehničnega poročila zajema vse aktivnosti, povezane z vzorčenjem proizvodov, ki se začne z začetnim načrtovanjem vzorčenja in konča z dostavo in uradnim prenosom laboratorijskega vzorca v laboratorij. To tehnično poročilo se osredotoča na odvzem enega vzorca. Ponavljajoče se vzorčenje je zunaj obsega uporabe, saj mejni pogoji za rutinsko preskušanje blizu meje še niso opredeljeni (npr. potrebna zanesljivost). Čeprav ponavljajoče se vzorčenje ni zajeto, pogoji, navedeni v tem tehničnem poročilu, veljajo za posamezni vzorec in za vzorec, ki je del serije.
