19、 document contains recommendations for on-site quality control of geotextiles and geotextile-related products as part of the site quality assurance system. It describes procedures for verifying that: the correct product is delivered to site; the product is handled and installed in the correct manner

20、; the specifications are met. This document contains an annex showing five examples of report forms for use on the site and a bibliography. 2 Terms and definitions For the purposes of this document, the terms and definitions given in prEN ISO 10318 and the following apply. The term “product“ used in

21、 this document refers to a geotextile or geotextile-related product. 2.1 design specification document which defines the application in which the product is to be used and where the functions, the characteristics and the design specification values of the characteristics required for use in the work

22、s are stated 2.2 product specification value value of a product characteristic as stated by the manufacturer, e.g. in the accompanying documents for CE marking. This value represents the mean value minus (and/or plus) one time the tolerance value(s) corresponding to the 95 % confidence level (as def

23、ined e.g. in EN 13249:2000, 5.2). By extension, this definition can also be applied to other characteristics described in Table 1 of the relevant product/application standard (see bibliography) and also to characteristics such as mass per unit area and thickness 2.3 sample part of the product, taken

24、 over the whole width, from which specimens are taken for testing 2.4 specimen (test specimen) part of the sample used for an individual test 2.5 test result (of a sample) mean of the results obtained on the specimens tested 2.6 test lot quantity of products considered as one unit for sampling and t

25、esting. This can be the total area to be covered by the product in the works 2.7 delivery lot quantity of product delivered on site in a given period of time, which can be submitted to a single approval. Delivery lots are evaluated independently of each other CEN/TR 15019:200552.8 safety standard hi

26、gh application where long-term strength is a significant parameter and/or where the product plays a decisive role in the safety of the construction and the stability of the works, e.g. reinforcement (Eurocode 7 class 2) 2.9 safety standard normal all other applications than those defined under 2.9 (

27、Eurocode 7 class 1) 3 Principle The on-site quality control may consist of one or more of the following actions: evaluation of the compliance of a delivered product with the design specification (see 4.1); evaluation of the compliance of site-conditions with delivered product (see 4.2); inspection o

28、f handling and storage conditions (see 4.3); inspection of product installation (see 4.4); taking samples for evaluation of compliance with the design specification (see 4.5); placing and extracting control samples to check damage during installation (see 4.6); placing control samples to check the b

29、ehaviour with time (see 4.7). 4 Procedures 4.1 Evaluation of compliance of delivered product with the design specification (see Annex A.2) The following should be completely checked and documented by the contractor and randomly supervised by the client immediately after delivery: is the product mark

30、ing and the information affixed to the unit in accordance with EN ISO 10320? is the CE-marking affixed to each unit? is the information required in Table 1 of the relevant product/application standard available? is the product in accordance with the purchase order and the delivery note? are the spec

31、ification values of the product in accordance with the design specification? is the delivered product by the values tested conform with the design specification? 4.2 Evaluation of compliance of site conditions with the delivered product (see Annex A.3) Generally, the actual site conditions fit with

32、the design of the structure, but unforeseen circumstances may jeopardize this. In case they are not complying with the design and the specifications, the contractor and the client should check, before installation of the product, if the product characteristics meet the actual site conditions. As an

33、example, they should check the compliance of the product characteristics with: CEN/TR 15019:20056 soils to be covered with fill material on site (influence on damage during installation, chemical factors e.g. by high or low pH); method of placing and compacting the fill (influence on damage during i

34、nstallation); stress by site traffic (rutting) ; influence of site conditions on the behaviour and the durability of the product. 4.3 Inspection of handling and storage conditions Site handling of the units (rolls or packages) should comply with the recommendations of the manufacturer and one should

35、 ensure that damage to the product e.g. surface abrasion, slitting, notching or tearing is prevented (see Annex A.2). This should be checked by the contractor and at random by the client. Products should be stored in accordance with the manufacturers instructions. Prolonged exposure to weathering sh

36、ould be prevented by storage under cover or in the original packaging supplied by the manufacturer. If the product is damaged: see 6. 6.1. 4.4 Inspection of product installation During installation, it should be checked by the contractor and at random by the client, that the installation of the prod

37、uct is consistent with the design/drawings and specification (see Annex A.2 and A.3), i.e. that: product is laid as shown on the drawings or as described in the specification (e.g. installation plan); machine direction of the product is placed according to the design; there is sufficient overlapping

38、 between rolls; direction of overlapping is correct; joints or seams are applied where necessary; product is used “top-side up“ ( with the correct side against soil/building). Products, whose functional properties can be affected by water, should be installed under dry circumstances. Products, which

39、 can be damaged by freezing (vegetation mats, etc.), should be installed when the temperature is above freezing point. 4.5 Sampling for evaluation of compliance with the design specification (see Annex A 3 and A 4) Tests are proposed for evaluation of compliance with the design specification. The co

40、ntractor therefore should implement a quality control procedure of products delivered to the construction site (see 4.5.1). If the client requires additional control tests to identify the product delivered to site and its compliance with the specification, these tests should be specified in the cont

41、ract documents (see 4.5.2). The area of product to be included in each test or delivery lot has to be agreed between all contractual parties involved. The samples should be taken well in advance to allow obtaining the test results at the latest on the day of installation. The evaluation procedure is

42、 given in chapter 5 and the actions, which result in chapter 6. The number of samples and selection procedure should be defined in the contract documents. The number of samples required should be a function of: importance of the product for the safety of the works; CEN/TR 15019:20057 area of product

43、 used in the works. 4.5.1 Control of products delivered to the construction site Samples to determine product compliance with the specification should be taken by the contractor together with the supplier of the product. The testing of the materials delivered to the construction site is the responsi

44、bility of the contractor. Number of samples required: a) safety standard “high“ applications: 1 sample every 6 000 m, with a minimum of 2 samples above 1 000 m b) safety standard “normal“ applications: 1 sample every 10 000 m, with a minimum of 1 sample above 1 000 m These control tests can be omitt

45、ed, if the product is certified on the basis of a voluntary certification system where the following tasks are performed by the conformity assessment body: initial type testing of the product; initial inspection of the production and of the factory production control; continuous surveillance, assess

46、ment and approval of the factory production control; audit testing of specimens sampled in the factory, in the market or on the construction site. 4.5.2 Control tests by the client Control tests are the responsibility of the client. Samples should be taken by a representative of the client, a confor

47、mity assessment body or a representative of an inspection body, together with the contractor at random from a delivery lot, to determine the identity of the product and its compliance with the design specification.Number of samples required for control tests: a) safety level “high“ applications : 1

48、sample every 30 000 m, with a minimum of 1 test above 1 000 m b) safety level “normal“ applications : 1 sample every 50 000 m, with a minimum of 1 test above 10 000 m 4.5.3 Test programme For sampling EN 963 should be applied, i.e. samples should be taken not less than 5 m from the end of the roll i

49、n machine direction and over the whole width in cross machine direction. The sampling report should be signed by all parties involved (e.g. client, contractor, supervisor). An example of such a sampling report is given in Annex A.4. The location of each sample should be described exactly. The actual tests to be performed follow from the design specification and the purpose (evaluation of identity and of conformity with specification). They should be defined in the contract on the basis of the design
