This document specifies the requirements related to dimensional, mechanical, optical and thermal characteristics of thermoplastic films for mulching applications in agriculture and horticulture.These mulch films are intended to be removed after use and not incorporated in the soil.These mulch films are not intended to be used for soil disinfection by fumigation. Films for this application are in the scope of prEN 17098-1[1].It specifies a classification for durability of mulching films and the test methods referred to in this document.This document is applicable to thermoplastic mulch films, used for agriculture and horticulture in Europe, based on polyethylene and/or ethylene copolymers, of the following types:- transparent films;- black films;- reflective films (e.g. white films, black/white films and black/silver films);- films of other colour(s) for weed control (e.g. green, brown).This document also defines installation, use and removal conditions of mulch films.NOTE Mulch films are considered as highly contaminated by soil and vegetal residues: the observed rates (or levels) of contamination of mulch films can vary from 70 % to 90 %. Therefore the film thickness is a key factor on the rate of contamination, the thinnest films (e.g. less than 25 µm) will be the mostly contaminated, difficult, expensive to remove, recover and recycle.

This European standard specifies the requirements related to dimensional, mechanical and optical characteristics of thermoplastic films and tubes used during the manufacture of silage and designed to last at least one year for protecting fodder.It specifies a classification for the durability of silage films and the test methods referred to in this standard.This European Standard is applicable to transparent, black, white or coloured (e.g. black/white) thermoplastic silage films based on polyethylene, ethylene copolymer, EVOH and polyamide.These films are intended for covering bunker silos, silage tubes or silage clamps for preserving forage. They protect the forage and preserve it from rain and air. These films are not intended to cover bales piles (e.g. straw bales and hay bales).Silage films obtained by sealing two or more films in machine direction are out of the scope of this document.This European Standard also defines installation, use and removal conditions of silage films. It defines the conventional useful lifetime, as well as rules that allow evaluating the remaining use potential in the event of a failure before the normal end-of-use date.NOTE These rules allow estimating the residual value of the films. These provisions only apply to the film itself and the damage it has undergone. Any other problem falls within the scope of professional practices and the general terms and conditions of sale.

This document specifies a method for the determination of bending stiffness using the resonance method. This method gives only a single result for each test piece tested, although in general, bending stiffness values may depend on which surface of the material forms the inner surface of the arc resulting from bending forces. The bending stiffness of a very wide range of papers and boards can be measured using this method. However, for some materials, such as those listed below, the measured numerical values will not be strictly identical with bending stiffness as defined in 3.1: This method is not applicable to corrugated boards.

This European Standard specifies the methods of test for determination of the properties of high-pressure decorative laminates as defined in Clause 3. These methods are primarily intended for testing the sheets specified in EN 438-3, EN 438-4, EN 438-5, EN 438-6, EN 438-8, and EN 438-9.The precision of the test methods, specified in this European Standard, is not known because inter-laboratory data are not yet available. When inter-laboratory data will be obtained, precision statements will be added to the test method at the following revision. For those test methods having an end point determination based on subjective judgement, it is not meaningful to make a statement of precision.

This European standard describes two representative methods for the determination of the extractable amount of specificprimary aromatic amines (PAA) in a water extract of paper, board and pulp samples by means of HPLC with MS/MSdetection which basically differ concerning the choice of the mobile and stationary phases. Deviating from this standardfurther methods may be applicable if it can be shown that comparable results can be achieved. A validation must be carriedout by each laboratory.It is applicable for the determination of the 22 primary aromatic amines (PAA) mentioned in the annex of directive2002/61/EC of 19th July 2002 amending Council Directive 76/769/EEC relating to restrictions on the market and use ofcertain dangerous substances and preparations (azocolourants) which are classified as carcinogenic categories 1A and 1Baccording to the CLP regulation and aniline.The method described by this standard also shall be applicable for the determination of further primary aromatic amines(PAA). A validation for every further analyte has to be done by the laboratory using this method.The extractable amount of a primary aromatic amine (PAA) is expressed in mg PAA per litre water extract. This method issuitable for the determination of PAA with a working range of about 0,001 – 0,020 mg/l water extract.NOTE: Deviating from this standard further methods may be applicable, if it can be shown that comparable results can beachieved. A validation must be carried out by each laboratory.

This document specifies a method for the determination of the slow release properties of nutrients from coated fertilizers. pH-dependent hydrolysis and degradation by biological or microbial mechanisms are excluded. The specified method is only applicable to products releasing any nutrients by means of a non-biological process (i.e. those where the nutrients are released by a physical mechanism). Microbial attack on the coating (e.g. sulfur coated fertilizers) and the consequences thereof are not measurable by the technique described. This method involves a lengthy process which may not be appropriate for day to day testing purposes. Accelerated methods can be used provided they are correlated with this document. An example of such an accelerated method is described in Annex B. Regression analysis can also be used for this purpose.
