This European standard specifies mastic asphalts for waterproofing, stales their characteristics, the test methods to be used to verity these characteristics. and their manufacturing and transport recommendations. It aplies to mastic asphalts used for waterproofing or by application on polymer bitumen sheets in the construction and clvil engineering fields, such as roofing, parking. tanking, bridge decks (concrele and ste. It […]

1 Scope This European Standard specifies a test method (phase 2/step 1) and the minimum requirements for fungicidal activity of chemical disinfectant and ant iseptic products that form a homogeneous physically stable preparation in standardized hard water. This European Standard is appl icable to products for use in the veterinary field, i.e. in the . breeding, husbandry, product ion, transport […]

1 Scope This European Standard specifes a gas chromatographic method using column switching for the quantitative determination of individual organic oxygenate compounds in the range 0,17 % (m/m) to 15 % (m/m) and total organically bound oxygen up 3,7 % (m/m) in unleaded petrol having a final boiling point not greater than 220 °C. NOTE 1 The final boiling point […]

4 GENERAL PRINCIPLES 4.1 Under the requirements of this European Standard, the manufacturer has sole responsibility for providing a declaration of competence that a person in its employ performing NDT tasks has pre-requisite qualification and has successfully passed qualification examinations, conducted under the aegis of the manufacturer, in one or more of the NDT methods covered by this standard, in […]

This standard specifies requirements for classification of wire electrodes, wires and rods for gas shielded metal arc welding, gas tungsten arc welding, plasma arc welding and submerged arc welding of stainless and heat resisting steels. The classification of the wire electrodes, wires and rods is based on their chemical composition. 2 Normative references This European Standard incorporates by dated or […]

1 Scope The present standard specifies the test method for measuring the transmitted force developped by motorized shutters and blinds (hold to run control, semi-automatic or automatic) in the precise conditions of use specified in prEN 13120:1998, prEN 13561:1999, and prEN 13659:1999. This applies to the following motorized products: Guided internal blinds: venetian, roller, vertical and pleated blinds. External awnings: […]

5 Limitations and interferences 5.1 Limitations The digestion fails to determine nitrogen in the form of azide, azine, azo-compounds, hydrazine, nitrate, nitrite, nitroso-compounds, oxime, semi-carbazone and ntrile. 5.2 Nitrate/Nitrite The presence of nitrate or nitrite may cause rratic results, but not at the levels normally found in sludge. 6 Reagents During the analysis, use water of purity grade 2 a昭s […]

1 Scope This Intemational Standard describes test methods to determine the resistance of stainless steel surgical and dental hand instruments against autoclaving, corrosion and thermal exposure. The requirements for such tests are detined and stated in the product standard along with the number of cycles for each test procedure. Other, additional, tests may also be required (see the Introduction). 2 […]

3 Classification The classification includes all-weld metal properties obtained with a tubular cored electrode and appropriate shielding gas combination as given below. The classification is divided into five parts: 1) the first part gives a symbol indicating the product/process to be identified; 2) the second part gives a symbol indicating the chemical composition of the all-weld metal; 3) the third […]

1 Scope This European Standard specifies a method for the determination of the dimensional stability of insoles, irespective of the malerial, after immersion in water. 2. Nomative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For […]
