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.

Draft international standards adopted by technical committees are circulated to member bodies for approval before they are accepted as international standards by the ISO Council. They are approved according to ISO procedures that require at least 75% approval by voting member institutions.

ISO standar internasional 6713 dikembangkan oleh komite teknis ISO/TC 35 (Cat dan pernis).

ISO 6713 was first published in 1980. Edisi kedua membatalkan dan menggantikan edisi pertama, which constituted a technical revision.

ISO 6713-1984 “Pembuatan ekstrak asam lak dalam bentuk cair atau bubuk” untuk cat dan pernis

Ruang lingkup dan bidang aplikasi
This standard describes the preparation of acid extracts as test solutions for the determination of the “larut” metal content of paints and related products in liquid or powder form.

Acid extracts were prepared in 0,07 mol/l hydrochloric acid, which was chosen as an approximation of the acid in the stomach.

This standard does not apply to dried or crushed paint films (lihat ISO 6714).

Peringatan – The procedures described in this standard are complex and should therefore be performed by personnel with appropriate experience in these analytical procedures. Sufficient accuracy can only be obtained if all details of the separation and extraction procedures are strictly followed.

3 Definisi
For the purposes of this Standard, definisi berikut ini berlaku.

3.1 Pigmen

All particulate matter was insoluble in the selected extraction solvent (6.2).

3.2 “Soluble” metal content of liquid coatings

The metal content of the pigment soluble in a specified dilute acid plus the total metal content present in the liquid part of the paint.

Catatan 1: The dilute acid defined in this standard is 0.07mol/l hydrochloric acid.

3.3 “Soluble” metal content of paint in powder form

Metal content of paints soluble in specified dilute acids (Lihat Catatan 3.2).
