PD CEN/TS 151191:2018CEN/TS 15119-1:2018 (E) 4 Introduction The emissio

29、ns from preservative treated wood into the environment need to be quantified to enable an environmental risk assessment to be made of the treated wood. This document describes a laboratory method for the determination of emissions by leaching from preservative treated wood where the preservative tre

30、ated wood is not covered and not in contact with the ground or the water. There are two situations in this case where such emissions could enter the environment: a) Emissions from preservative treated wood stored outside in the storage yard of a preservative treatment site. Rain falling on the treat

31、ed wood could produce emissions that run off into surface water and / or soil; b) Emissions from treated wood used in commodities exposed in Use Class 3. This is the situation in which the wood or wood-based product is not covered and not in contact with the ground. It is either continually exposed

32、to the weather or is protected from the weather but subject to frequent wetting. Use classes are defined in EN 335 and categorise the biological hazard to which the treated commodity will be subjected. The Use Classes also define the situation in which the treated commodity is used and determine the

33、 environmental compartments (air, water, soil) which are potentially at risk from the preservative treated wood. Rain falling on treated wood in Use Class 3 could produce emissions that run off into surface water and/ or soil. The method is a laboratory procedure for obtaining water samples (leachat

34、e) from treated wood exposed out of ground contact, at time intervals after exposure. The quantities of emissions in the leachate are related to the surface area of the wood and the length of exposure, to estimate a flux in milligrams per square metre per day. The flux after increasing periods of ex

35、posure (e.g. 1 year, 10 years) can be estimated. NOTE The leachate can also be tested for eco-toxicological effects. The quantity of emissions can be used in an environmental risk assessment of the treated wood. The test can be applied to wood treated using a penetrating process or superficial appli

36、cation (brush, spray or dipping), or to treated wood which has an additional surface treatment (e.g., paint that is applied as a requirement for commercial use). PD CEN/TS 151191:2018CEN/TS 15119-1:2018 (E) 5 1 Scope This Technical Specification describes a laboratory method for obtaining water samp

37、les from preservative treated wood exposed out of ground contact (wood held in the storage yard after treatment and which has been in conditions designed to simulate outdoor, out of ground contact situations), at increasing time intervals after exposure. 2 Normative references The following document

38、s, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 5667-3, Water quality

39、Sampling Part 3: Preservation and handling of water samples (ISO 5667-3) 3 Description of the test method 3.1 General considerations The principal agent for causing emissions from wood during open-air storage in the yard and in Use Class 3 is rainfall. Wood exposed in above ground situations is subj

40、ected to intermittent wetting by rainfall and drying of the wood surface between the rainfall events. These wetting and drying cycles are simulated by the method described in this document. It is assumed that emissions obtained by short-term immersion in water are indicative of the emissions which w

41、ill occur during exposure to rainfall. The wood, in the case of wood treated with a wood preservative, shall be representative of commercially treated wood. It shall be treated in accordance with the preservative manufacturers instructions and in compliance with appropriate standards and specificati

42、ons. The parameters for post-treatment conditioning of the wood prior to the commencement of the test shall be stated. The wood samples used shall be representative of the commodities used. The composition, amount, pH value and the physical form of rainfall are important in determining the quantity,

43、 content and nature of emissions from wood. However, simulating a realistic rainfall regime in the laboratory is time-consuming, expensive and is likely to lack reproducibility, accuracy, precision and reliability. Two main immersion regimes are recommended as follows: 1. The 3 x 1 minute immersion

44、regime: A 1 minute immersion in water of the treated test specimens to simulate exposure to a rainfall event. There are three immersions or rainfall events per day, with test specimens allowed to dry for 3 hours between immersions simulating the wetting and drying cycle of natural exposure situation

45、s. The days of rainfall are set for 1, 3, 5, 8, 10, 12, 15, 17 and 19 days. NOTE 1 The OECD Emission Scenarios for Wood Preservatives 2013 (see bibliography) that are applied for the authorization procedure of the European BPR are based on the assumptions, that the total amount of rainfall per year

46、is 700 mm. The daily regime is intended to produce the same moisture content on the surface of the wood, and the same moisture content profile in the wood, and thus the same emission, as wood in a real exposure situation on a day during which rain occurs. It is intended that a 3 x 1 minute dip, ever

47、y third day, will give the same moisture content cycle in the wood, and the same emission from the wood, as exposure under real conditions. If the dipping and drying regime is continued for one year, the emission quantity and rate would be the same as the emission obtained from wood after exposure i

48、n a real situation in a region of Europe where there is 700 mm of rain per year, with rain events occurring on 260 days of the year. PD CEN/TS 151191:2018CEN/TS 15119-1:2018 (E) 6 2. The 2 x 1 hour immersion regime: A 1 hour immersion in water of the treated test specimens to simulate exposure to a

49、rainfall event. There are two immersions or rainfall events per day, with test specimens allowed to dry for 4 hours between immersions simulating the wetting and drying cycle of vertical natural exposure situations. The days of rainfall are set for 1, 3, 5, 8, 10, 12, 15, 17 and 19 days. The applicant must provide adequate discussion of the conditions of these regimes (e.g., purpose is to estimate emissions from wood that is treated and then exposed vertically or horizontally) for data to be acceptable when using these
