What is an ETA?  ETA是什么？
The European Technical Assessment (ETA) is a document providing information about the performance of a construction product,  to be declared in relation to its essential characteristics. This definition is provided in the new Construction Products Regulation (EU/305/2011) entered into force on 1st of July 2013 in all European Members States and in the European Economic Area.
歐洲技術評估（ETA）是一個提供關于建筑產品基本特征的性能聲明的信息文件。 該定義由最新的CPR建材法規(EU/305/2011)提供，該法規于2013年7月1日起在所有歐洲成員國和歐洲經濟區強制實施。

The ETA provides a way for the manufacturer to CE-mark a product. The ETA can be issued in the following cases:
ETA為工廠加貼CE標識提供了一個方法。ETA可以在以下情況下頒發：
§  The product is not or not fully covered by any harmonised technical specification such as European Assessment Documents (EADs) or European Standards (hENs)
產品沒有或者沒有完全被任何的協調技術規范覆蓋，例如歐洲評估文件(EADs)或者歐洲協調標準(hENs)

§  The product is covered by a European Assessment Document (EAD)
該產品被被歐洲評估文件覆蓋(EAD)
The ETA is valid in all 28 European Member States and those of the European Economic Area, as well as in Switzerland and Turkey. The ETA can be obtained upon request by a manufacturer (or its authorised representative) in countries where a Technical Assessment Body (TAB) has been designated according to the Construction Products Regulation. The ETA is the basis for a Declaration of Performance (DoP) to be drawn up by the manufacturer.
ETA在所有28個歐洲成員國和歐洲經濟區，以及瑞典和土耳其有效。ETA可以經工廠（或者其授權代表）的請求，在技術評估機構（TAB）根據建材法規已經被指定的國家獲得。
The ETA contributes to establish confidence in the performance of the essential characteristics of a construction product for its intended use. The ETA route supports the free movement of construction products and thus the Single European Market.
ETA有助于建立建材產品及其用途的基本特征的性能的信任。 ETA路線支持建材產品和單一歐洲市場的自由活動。
An ETA contains the following information:
一個ETA包含下面的信息

§  General information on the manufacturer and the product type, name and manufacturing plant
制造商和產品型號名稱的基本信息以及制造工廠

§  Performances of the product to be declared and references to the methods used for its assessment
產品的性能聲明和對應采用的評估方法

§  ?Technical details necessary for the implementation of the AVCP system
AVCP系統實施必要的技術細節
An ETA which has been issued after 1st of July 2013 is valid of indeterminate duration. On the EOTA website references to issued ETAs are published.
2013年7月1日之后頒發的ETA有效期是未確定的，在EOTA網站頒發ETA的參考已經被發布。
 
What is important to know about the changes from 1st of July 2013 with regard to ETAs?
知道2013年7月1日起ETA的變化哪些是重要的

ETAs which were issued up to 30 June 2013 (so called European Technical Approvals) remain valid until the end of their validity period. They can be used by manufacturers as European Technical Assessments. This type of ETAs will disappear from the market throughout the year 2018. These ETApprovals were based on ETA Guidelines or issued upon common agreement of the Approval Bodies.
截止2013年6月30日頒發的ETA（所謂的歐洲技術審批）在其有效期限內仍然有效。它們可以被制造商作為歐洲技術評估使用。這種類型的ETA將會于2018年在市場消失。這些歐洲技術審批是基于ETA指南或者根據批準機構的共同協議頒發。
As of 1st of July 2013 ETAs are based on adopted European Assessment Documents (EADs) or ETAGs used as EADs. ETAssessments issued on the basis of "ETAGs used as EADs" remain valid after development of the ETAGs into EADs.
因2013年7月1日的ETA是基于歐洲技術文件(EADs)或者ETAGs作為EADs。歐洲技術評估基于‘ETAGs作為EADs’頒發的仍然有效，在ETAGs發展為EADs之后。
 
What is important to know about ETAs in the framework of the Construction Products Regulation? 
關于建材法規的ETA框架重要了解哪些

In accordance with regulation (EU) No 305/2011 (CPR), a manufacturer is responsible to provide a declaration of performance (DoP) for a construction product covered by a European Technical Assessment (ETA) which is issued for it, when such a product is placed on the market. The CE marking shall be affixed on this product indicating that the manufacturer is taking responsibility for the conformity of this product with the declared performance.
根據CPR法規(EU) No 305/2011，對于頒發的ETA覆蓋的建材產品，制造商有責任提供DOP性能聲明，當產品在市場銷售的時候。CE標識應當加貼在產品上來表明制造商對其聲明的產品性能的符合性負責。

A European Technical Assessment (ETA) is issued on the basis of a European Assessment Document (EAD), or ETAG used as EAD, which describes the type of product(s) it applies to, the list of essential characteristics in relation to the intended use foreseen by the manufacturer, the methods and criteria for assessing the performance in relation to the essential characteristics, and the principles for the applicable factory production control.
The ETA’s focusses on the claims of the manufacturer, i.e. the essential characteristics the manufacturer wants to declare in relation to the intended use(s) he foresees.
一個ETA是基于歐洲技術文件(EAD)，或者ETAG作為EAD頒發，描述了其適用的產品類型，跟制造商可預見的用途相關的基本特征列表，跟基本特征相關的性能評估的方法和標準，以及適用的工廠生產控制的原則。

As a consequence of the CPR, its Commission delegated regulations (delegated acts) and further European Commission Services’ interpretation:
§  Some essential characteristics that are relevant in a specific type of construction works and/or in certain Member States may not be identified and the associated performances not declared (e.g. a national regulatory requirement not expected in relation to its type or location under the manufacturer’s foreseen intended use), or/and a declared performance may not fit a specific construction work requirement.   
Therefore, CE marking based on an ETA supports the placing on those markets the manufacturer is intending to service with its construction product. But, due to (potential) lack of consideration of essential characteristics relevant for certain Member States, it does not necessarily serve the free circulation amongst EU 28 countries.
 
§  The decision on a product-type, i.e. to which product the ETA applies and the content of the declaration of performance that may be drawn up, lies with the manufacturer; the ETA is focusing on the essential characteristics which the manufacturer wants to declare a performance for and, in general, no detailed identification of the assessed product is expected.
Any modification in the product may not be identified or/and traced back to the DoP, referring to the ETA and EAD, when the performances related to the declared essential characteristics are not changed. However such modifications may affect other characteristics that could influence, to a significant extent, the behavior of the product during the construction phase or once installed or incorporated in the construction work.
 
§  The manufacturer is responsible for defining the intended use of his product which is reflected in the ETA. The EAD cannot specify assumptions on the use of the product or on conditions related to its assessment or performance, which will form a requirement, a constraint, on any other similar product to which the EAD may apply. To draw up technical information, of importance for the construction work performance or behavior, related to design and installation, life phase between manufacture and incorporation (e.g. packaging, transport, storage …) or working life (e.g. use, maintenance, replacement or repair) is the responsibility of the manufacturer. 
 
§  Assumption on the working life of a construction product in relation to an expected durability, related to its’ assessment or performance, is also being considered as creating a requirement, a constraint, on any other similar product to which the EAD may apply. Therefore, at the request of another manufacturer the related assessment methods and criteria, in another EAD may lead to deviations in the “assumed working life”.
Normally products should be assessed for the aging scenario based on cycles, time to …, etc. It is up to the user to make a decision, based on the manufacturer’s declaration on durability: cycles, time to …, referring to the assessment method given in the EAD, which performance is fitting the expected construction work life.
EOTA members (TAB) have to develop and adopt an EAD following strict rules resulting from the implementation of the CPR, despite their overall competence and technical knowledge on all related aspects for products and their use and behavior in works. The TABs need to disregard some further requests of construction stakeholders on the sustainable competitiveness of the construction sector when issuing the ETA based on the EAD.
Based on this information, any and all users remain liable to check and make an appropriate choice that the products made available on their market with harmonized essential characteristics are fitting the whole set of conditions and requirements for the construction wor
