DIN EN 117:2013-01 EN 117:2012 (E) 4 Introduction This documen
22、t describes a laboratory method of testing which gives a basis for assessment of the effectiveness of a wood preservative against the Reticulitermes species of European termites. It allows the determination of the concentration at which the product completely prevents attack by these insects of impr
23、egnated wood of a susceptible species. This laboratory method provides one criterion by which the value of a product can be assessed. In making this assessment the methods by which the preservative can be applied should be taken into account. It is further recommended that results from this should b
24、e supplemented by those from other appropriate tests, and above all by comparison with practical experience. When products which are very active at low concentrations are used it is very important to take suitable precautions to isolate and separate, as far as possible, operations involving chemical
25、 products, other products, treated wood, laboratory apparatus and clothing. Suitable precautions should include the use of separate rooms, areas within rooms, extraction facilities, conditioning chambers and special training for personnel (see also Annex C for environmental, health and safety precau
26、tions). DIN EN 117:2013-01 EN 117:2012 (E) 5 1 Scope This European Standard specifies a method for the determination of the toxic values of a wood preservative against the Reticulitermes species of European termites1). This method is applicable to: water-insoluble chemicals which are being studied a
27、s active insecticides; organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and water-soluble materials, for example salts. NOTE This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84. 2 Normative refere
28、nce The following documents, 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
29、ISO 3696, Water for analytical laboratory use Specification and test methods (ISO 3696) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 representative sample sample having its physical or chemical characteristics identical to the volumetric a
30、verage characteristics of the total volume being sampled 3.2 supplier sponsor of the test (person or company providing the sample of wood preservative to be tested) 4 Principle Impregnation of several sets of test specimens of susceptible wood with a series of solutions in which the concentration of
31、 preservative is ranged in a given progression. Exposure of these test specimens to specified colonies of Reticulitermes2)and assessment of the attack suffered after exposure under fixed conditions and over a fixed period. 1) The method can be applied not only to different species of Reticulitermes,
32、 but also to other species of the family of the Rhinotermitidae, adapting the conditions of temperature and humidity where necessary to the specific requirements of the species concerned. 2) In providing biological validation of individual species, it is essential that the locality of origin of each
33、 test termite species is given. The description of the locality should at least include the district name.
