ISO 2812-1-2017 pdf free.Paints and varnishes — Determination of resistance to liquids 一 Part 1: Immersion in liquids other than water. This document specifies general methods for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of liquids, other than water, or paste-like products (included implicitly in test liquids mentioned in the text). These methods enable the testers to determine the effects of the test liquid on the coating and, if necessary, to assess the damage to the substrate.

BS EN ISO 15091:2020 pdf free.Paints and varnishes – Determination of electrical conductivity and resistance. This document specifies a method for determining the electrical conductivity and the electrical resistance of coating materials. The conductivity is usually measured for water-borne paints and varnishes, including electrodeposition coating materials, and the resistance Is usually measured for solvent-borne paints and varnishes. If required. the resistivity of the coating material is calculated from either of these measurements. The method is applicable to products having a conductivity less than 5 uS/cm, corresponding to a resistivity greater than 200 kflcm. The conductivity of coating materials influences their processihility in the presence of an electric field. This is particularly important for electrodeposition paints and coating materials which are processed electrostatically. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

ISO 2811-1:2016 pdf free download.Paints and varnishes Determination of density Part 1:Pycnometer method Peintures et vernis — Determination de Ia masse volumique — Pa rtie 1: Méth ode pycnométrique. 8.2 Determination If working with a temperature-controlled chamber (see A), put the pycnometer (i) and the test sample next to the balance (±Z) in the chamber maintained at the specified or agreed temperature. If working with a water bath (see A) rather than a temperature-controlled chamber, put the pycnometer and the test sample in the water bath, maintained at the specified or agreed temperature. Allow approximately 30 mm for temperature equilibrium to be reached. Using the thermometer (), measure the temperature, tT, of the test sample. Check throughout the determination that the temperature of the chamber or water bath remains within the specified limits. Weigh the pycnometer and record the mass, ml, to the nearest 10 mg for 50 cm3 to 100 cm3 pycnometers and to the nearest 1 mg for pycnometers less than 50 cm3 in volume. Fill the pycnometer with the product under test, taking care to avoid the formation of air bubbles. Place the lid or stopper of the pycnometer firmly in position and wipe off any excess…

ISO 4628-10:2016 pdf free download.Paints and varnishes Evaluation of degradation of coatings Designation of quantity and size of defects, and of intensity of uniform changes in appearance Part 10:Assessment of degree of filiform corrosion Peintures et vernis — Evaluation de Ia degradation des revêtements— Designation de la quantité et des dimensions des défauts, et de l’intensité des changements uniformes d’aspect — Partie 10: Evaluation du degré de corrosion filiforme. This part of Iso 4628 specifies a method for assessing the amount of filiform corrosion developed from a scribed mark by measuring the length of the longest filament L and the most frequent length M of filaments. Pictorial examples provided in Annex A of this part of ISO 4628 illustrate different ratings for the length of the longest filament L and the most frequent length M of the filaments. A comparison of the test panels with the 12 pictures in Annex A does not supersede the obligatory numerical assessment (method I or 2). ISO 4628-1 defines a system used for designating the quantity and size of defects and the intensity of uniform changes in appearance of coatings and outlines the general principles of the system. This system is intended to be…

If no self-adhesive abrasive paper is available, regular abrasive paper may be used together with double- sided adhesive tape. In case the strips of abrasive paper are cut at an angle (45°) prior to adhering (see Figure 3), a minimum length of 173 mm is required. NOTE It is common to agree on the abrasive paper on the basis of the identification of the abrasive wheel manufacturer. 5.3 Weights, to increase the test load up to about 10 N by attaching to each arm (see 5.1.2). NOTE For a common apparatus, the minimum test load which is exerted solely by the abrasive wheel and the arms without additional weights is 2,7…
