DIN Standards Committee Materials Testing

Overview

Sampling depends on the product and the size of the container but not on the type of product, such as paint, varnish, binder, pigment, extender or solvent. ISO 1513 specifies both the procedure for preliminary examination of a single sample as received for testing, and the procedure for preparing a test sample by blending and reduction of a series of samples representative of a consignment of paint, varnish or related product. The samples of the product to be tested shall be taken in accordance with this document. Correct sampling forms the basis for the subsequent tests and their results. The various sampling procedures need to be carried out with great care by operators having the required knowledge and experience. The general instructions in this International Standard are intended to supplement this knowledge and experience and are applicable to most situations. However, some products might require special sampling precautions that are not given in this International Standard. Therefore, special vigilance will be necessary on the part of operators to take note of any unusual characteristics exhibited by those products. It is also essential that operators adhere to any special precautions in accordance with product specifications and national safety regulations. This International Standard specifies procedures for the sampling of paints, varnishes and raw materials. It includes such products and liquids which, without undergoing chemical modification, are capable of being liquefied when heated up, and powdered, granulated and pasty materials. Samples may be taken from containers, for example cans, drums, tanks, tank wagons or ships tanks, as well as from barrels, sacks, big-bags, silos or silo wagons, or from conveyor belts. This International Standard does not deal with the sample preparation for testing or reduction of the samples thus taken. This is dealt with in ISO 1513. The committee responsible for this standard is NA 002-00-07 AA "Allgemeine Prüfverfahren für Beschichtungsstoffe und Beschichtungen" ("General test methods for coating materials and coatings") at DIN.
