Construction products: Assessment of release of dangerous substances - Guidance on the statistical assessment of declared values - Part 1: Principles and rules of application
This Technical Report provides guidance on the statistical assessment of declared values with respect to the release, emission and/or content of dangerous substances. This Technical Report provides statistically-based criteria for type-testing (TT), further-testing (FT) and where a product has been shown to be consistent with measured values for the release, emission or content that are significantly below the declared values, the point where no-further-testing (NFT) is permitted.
A series of fundamental principles are defined in the present document and two statistical approaches are defined. The first approach is to use assessment by variables and this approach requires the data to be normally or log-normally distributed. This approach is recommended as the default option. The alternative approach based on assessment by attributes is appropriate for data sets that are not normally or log-normally distributed. The downside to this form of assessment is that more test data are needed for the same level of reliability. The present document introduces these assessment procedures and CEN/TR 16797-2 provides more detail and the statistical proof that they satisfy the principles defined in this document. With both of these approaches the minimum frequency of testing is a function of the distance between the mean value and declared value and the variability of the data set, i.e. the sample standard deviation.
To reduce the costs of testing, production plants producing a similar product may share data, e.g. be grouping the product into clusters for statistical assessment of declared values. Rules for the use of clusters are given in CEN/TR 16797-2.
CEN/TR 16797-2 also contains rules for identifying outliers within a data set and guidance on using tests other than the reference method for FT.
A list of tasks for product technical committees is given in CEN/TR 16797-2 as is a model clause for including in product standards and rules of applications that may be cited in the product standard or copied into product standards.

Gradbeni proizvodi – Ocenjevanje sproščanja nevarnih snovi - Navodilo za statistično ocenjevanje deklariranih vrednosti - 1. del: Načela in pravila uporabe
To tehnično poročilo CEN zagotavlja navodilo za statistično ocenjevanje deklariranih vrednosti v zvezi s sproščanjem, emisijami in/ali vsebnostjo nevarnih snovi. To tehnično poročilo zagotavlja merila na podlagi statističnih podatkov za tipsko preskušanje (TT), dodatno preskušanje (FT), kadar pa je dokazana skladnost proizvoda z izmerjenimi vrednostmi za sproščanje, emisije ali vsebnost, ki so bistveno nižje od deklariranih vrednosti, točko, ko ni dovoljeno dodatno preskušanje (NFT).
V tem dokumentu so opredeljeni sklop temeljnih načel in dva statistična pristopa. Prvi pristop zajema uporabo ocenjevanja s spremenljivkami, pri čemer je za ta pristop potrebna normalna ali logaritemsko normalna porazdelitev podatkov. Ta pristop se priporoča kot privzeta možnost. Alternativni pristop, ki temelji na ocenjevanju po atributih, je primeren za podatkovne sklope, ki niso normalno ali logaritemsko normalno porazdeljeni. Slaba plat te oblike ocenjevanja je, da je za enako raven zanesljivosti potrebnih več preskusnih podatkov. Ta dokument uvaja te postopke za ocenjevanje, FprCEN/TR 16797-2 pa zagotavlja več podrobnosti in statistični dokaz, da so izpolnjena načela iz tega dokumenta. Pri obeh pristopih je najmanjša pogostost preskušanja funkcija razdalje med povprečno vrednostjo in deklarirano vrednostjo ter spremenljivosti podatkovnega sklopa, tj. standardni odklon vzorca.
Da bi se zmanjšali stroški preskušanja, si lahko proizvodni obrati, ki proizvajajo podoben proizvod, delijo podatke, npr. proizvod povežejo v skupine za statistično ocenjevanje deklariranih vrednosti. Pravila za uporabo skupin so določena v tem dokumentu.
Dokument FprCEN/TR 16797-2 vsebuje tudi pravila za opredelitev osamelcev v podatkovnem sklopu in navodilo za uporabo preskusov, ki niso referenčna metoda za dodatno preskušanje.
Seznam opravil za tehnične odbore za proizvode je naveden v dokumentu FprCEN/TR 16797-2, pa tudi modelni člen, ki se vključi v standarde za proizvode, in pravila za uporabe, ki jih je mogoče citirati v standardu za proizvod ali kopirati v standarde za proizvode.
