This document specifies procedures for assessment and verification of constancy of performance (AVCP). This document is applicable to roomheaters, inset appliances and cookers which can be fired batchwise in fuel baskets for wood pellets (freestanding manually fuelled intermittent burning appliances). This document is applicable to appliances with fully integrated baskets for wood pellets which are integral component of the appliance. If the appliance is to be fired with wood logs or compressed untreated wood (wood briquettes), the configuration of the combustion chamber can be changed according to the instructions. Different fuels cannot be operated at the same time and they can be tested separately according the relevant part of EN 16510-2-x. The intended use of the appliances is space heating in residential buildings and can be cooking (when tested accordingly). These appliances can be supplied either as an assembled appliance or as a predesigned unit consisting of prefabricated components designed to be built on site in accordance with the specified assembly instructions. They only operate with the firedoors closed. This document is not applicable to: - mechanically fed appliances; - appliances with fan assisted combustion air; - appliances with boiler.

Neardomieji bandymai. 5 mm arba storesnių plokščių plieno gaminių ultragarsinis bandymas (atspindžio metodas)

This document describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities. This document is applicable to flat product in nominal thickness range of 5 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this document can be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed. This document also defines five quality classes for the flat product body (classes S0, S1, SA, S2 and S3) and five classes (E0, E1, E2, E3, E4) for the edges (see Clause 13). Other methods of testing (e.g. by phased-array) or other test equipment may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this document. In the event of a dispute, only the method defined in this document shall prevail. Testing of flat product of thickness less than 5 mm or higher than 200 mm may be the subject of special agreements between the parties concerned. The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection takes place in the presence of the purchaser or his representative1. A list of equivalent terms in several European languages is given in Annex A.

Organinės ir organinės-mineralinės trąšos. Ekstrahavimas vandeniu cheminiams elementams nustatyti

This document specifies the procedure for extraction of different organic and organo-mineral fertilizers with water to enable a subsequent determination of boron (B), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), phosphorous (P) and zinc (Zn). NOTE Extracts prepared by the procedure given in this document can also be applied for determination of other elements. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.
