Kata Pengantar
ISO (Organisasi Internasional untuk Standardisasi) adalah aliansi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Setiap lembaga anggota yang berminat pada suatu mata pelajaran yang telah dibentuk panitia teknisnya berhak untuk diwakili dalam panitia tersebut. Organisasi internasional pemerintah dan non-pemerintah yang berhubungan dengan organisasi standardisasi juga terlibat dalam pekerjaan ini. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang segala hal standardisasi kelistrikan.

Perkenalan
Sampling depends on the size of the product and container, but not on the type of product, seperti cat, pernis, paint powders, perekat, pigmen, fillers or solvents. ISO 1513 specifies procedures for the preliminary examination of individual samples received and for the preparation of test samples by mixing and reducing a series of samples representing a batch of paints, varnish or related products. Samples of the product to be tested have been collected in accordance with this document.

Correct sampling is the basis for subsequent tests and their results. Operators with the required knowledge and experience need to perform the various sampling procedures with great care. The general instructions in this document are intended to complement this knowledge and experience and apply to most situations. Namun, some products may require special sampling precautions not provided in this document; Karena itu, operators need to be particularly vigilant to pay attention to any abnormal characteristics exhibited by these products. Operators should be aware of product specifications and national safety regulations that may require special precautions.

1 Cakupan
The document specifies procedures for sampling paints and varnishes, including paint powders, and raw materials used in their manufacture. Such products include liquids and materials that are not chemically modified and can liquify when heated, as well as powders, granules and pastes. Samples may be taken from containers, such as cans, barrels, tanks, tank cars or ship tanks, or from barrels, sacks, large bags, silos or silo cars or conveyors.

This document does not address sample preparation for testing or reducing samples thus collected, which is covered in ISO 1513.
