33、volatile matter by volume (NVv) of coating materials by determining the practical dry-film density. This method determines the volume 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 o

34、f drying or curing.Using the non-volatile matter by volume results obtained in accordance with this part of ISO 3233, it is possible to 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

35、all products which can be applied by dipping.This part of ISO 3233 is not applicable to coating materials which exceed the critical pigment volume concentration (CPVC).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensabl

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

42、be suitable and adapted to the coating material under test. In addition the material of the plate shall not change 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 use

43、d subject to agreement between the interested parties, provided that the coated surface area is at least 5 600 mm2.Dimensions in millimetresFigure 1 Suitable plate for immersion5DIN EN ISO 3233-2:2014-10EN ISO 3233-2:2014 (E)5.2 Hook, made of stainless material or synthetic thread, for attaching the

44、 plate to the balance during weighing operations. The diameter of the wire shall not exceed 0,30 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,

45、 accurate to 0,1 mg. A single-pan balance is most convenient, and a useful modification is to 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 a

46、vailable.5.6 Immersion liquid of suitable density, in which the plate is immersed.NOTE Water 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

47、 of maintaining the specified or agreed test temperature to 2,0C (for temperatures up to 150C) 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 vol

48、atile materials is essential.Drying in a vacuum can be beneficial for certain applications. In 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 accordan
