The work of preparing International Standards is
21、 normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part
22、 in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particula
23、r the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this d
24、ocument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso

30、O 3251 and determination of dry film density on coated test panels by the Archimedes principle1 ScopeThis part of ISO 3233 specifies a method for determining the non-volatile matter by volume (NVv) of coating materials by determining the practical dry-film density. This method determines the volume
31、percentage of non-volatile matter in paints, varnishes and related products by measuring the density of a dry coating for any specified temperature range and period of drying or curing.Using the non-volatile matter by volume results obtained in accordance with this part of ISO 3233, it is possible t
32、o calculate the practical spreading rate of coating materials.This method specifies an additional shape of plate to those described in ISO 3233-1 and is suitable for all products which can be applied by dipping.This part of ISO 3233 is not applicable to coating materials which exceed the critical pi
33、gment volume concentration (CPVC).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

38、ating4 PrincipleThe non-volatile matter by volume is calculated from the quotient of the density of the coating material and the dry film, with the dry-film density being determined practically.5 ApparatusStandard laboratory apparatus together with the following:5.1 Metal plate, (40 1) mm (85 1) mm,
39、 with a small hole 2 mm to 3 mm from the edge. A plate with a tip on one of the shorter edges is easier to immerse in the coating material (see Figure 1).The material of the plate shall be suitable and adapted to the coating material under test. In addition the material of the plate shall not change
40、 its volume during contact with the coating material under test. The thickness of the plate is about 0,7 mm or it shall be agreed between the interested parties.Smaller plates may be used subject to agreement between the interested parties, provided that the coated surface area is at least 5 600 mm2
41、.Dimensions in millimetresFigure 1 Suitable plate for immersion2 ISO 2014 All rights reservedBS EN ISO 3233-2:2014ISO 3233-2:2014(E)5.2 Hook, made of stainless material or synthetic thread, for attaching the plate to the balance during weighing operations. The diameter of the wire shall not exceed 0
42、,30 mm because of surface tension effects.5.3 Beaker, of a size convenient for immersing the plate with a clearance of at least 10 mm and which can be accommodated in the balance case.5.4 Analytical balance, accurate to 0,1 mg. A single-pan balance is most convenient, and a useful modification is to
43、 replace the balance pan by a standard counterweight attachment.5.5 Support, for holding the beaker under the balance stirrup without jamming the pan damper, if a counterweight as recommended in 5.4 is not available.5.6 Immersion liquid of suitable density, in which the plate is immersed.NOTE Water
44、is a suitable immersion liquid for most coating materials. Other organic liquids are also suitable provided they do not attack the coating.5.7 Desiccator containing a suitable desiccant.5.8 Air oven, capable of maintaining the specified or agreed test temperature to 2,0C (for temperatures up to 150C
45、) or 3,5C (for temperatures above 150C and up to 200C). An air oven with forced ventilation shall be used.WARNING To protect against explosions and fire, careful handling of products containing flammable volatile materials is essential.Drying in a vacuum can be beneficial for certain applications. I
46、n such cases the conditions shall be agreed. Air ovens of the same type shall be used by all parties for referee tests.6 SamplingTake a representative sample of the coating material to be tested, in accordance with ISO 15528.Examine and prepare the samples for testing in accordance with ISO 1513.7 P
47、rocedure7.1 Number of determinations and preparationCarry out the determination in duplicate.Degrease and clean the plate (5.1). Dry the plate and hook at the specified temperature for 10 min, and cool in the desiccator.7.2 Determination of the practical dry-film density7.2.1 Determination of the ma
48、ss of the uncoated plate in air and in the immersion liquidWeigh the cleaned and dried plate plus hook in air to an accuracy of 1 mg (m1).Then place the plate in the beaker with the immersion liquid, e.g. water, and weigh to an accuracy of 1 mg (m2). Ensure that the plate is always immersed to the s
49、ame depth, with the liquid about 10 mm above the top of the plate. There shall be no air bubbles at any place on the plate (see Figure 2).NOTE If water is used as the immersion liquid, it is beneficial to add 1 or 2 drops of a wetting agent to ensure thorough wetting of the plate.
