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 tertarik pada suatu mata pelajaran yang telah dibentuk komite teknisnya berhak untuk diwakili dalam komite tersebut. Organisasi pemerintah dan non-pemerintah internasional yang bekerja sama dengan ISO juga terlibat dalam pekerjaan ini. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang semua masalah standardisasi elektroteknik.

ISO 23169-2020 “Field test methods for quality assessment of paints and varnished interior wall Coatings”

memperkenalkan
A typical interior wall coating system (lihat Gambar 1) consists of a thick filler, a coating primer, and two finishes. Sebagai akibat, the final quality of the interior wall depends on the entire paint system from the filler to the primer to the top coat. Selain itu, the quality of the coating conditions, such as film thickness and paint water dilution rate, has a significant impact on the final wall coating system.

Angka 1 — Typical interior wall coating system

1 Substrat (wall)
2 packing
3 Primer (1 coat)
4 Top coat (2 coats)
There is no standardized field test method in the market to check the performance of the entire system. Currently, so-called “field testing methods” rely on visual testing, nail scrubbing and touch. These methods are subjective, as the results may vary from person to person, even for the same wall coating system, and the results are not repeatable. Karena itu, this document provides standardized test methods for on-site wall paint evaluation. Using these standardized test methods can help distinguish between high quality and low quality interior wall paints.

ISO 23169-2020 “Field test methods for quality assessment of paints and varnished interior wall Coatings”

1 jangkauan
This document specifies two field test methods (field cleanliness [stain removal] and field resistance to wet scrubbing) for assessing the quality of interior wall coatings.

These tests are applicable to white coatings and light coatings where the tri stimulus value Y10 is greater than 25 measured on samples consisting of coatings coated on a black substrate.

The cleanability test can differentiate paint quality into 18% pigment volume concentration (PVC) and critical pigment volume concentration (CPVC). Field test methods for wet scrubbing resistance can differentiate coating quality when PVC is almost equal to or above CPVC.

3 Istilah dan Definisi
Untuk keperluan dokumen ini, istilah dan definisi yang diberikan dalam ISO 4618 dan artikel berikut ini berlaku.

3.1 Paint to water dilution ratio

The ratio of water to paint, expressed as a percentage of mass

3.2 Light Color Coating

Coatings with a tristimulus value of Y10 greater than 25 were measured by spectrophotometer on a sample consisting of coatings coated on a black substrate

Catatan 1: The tests shall comply with ISO 6504-3.

3.3 Kebersihan

The dry coating film is able to withstand the penetration of the dirt agent and is released from it through the cleaning process without removing more than the specified film thickness

[Sumber: ISO 11998:2006, 3.1]

3.4 Site wet scrubbing resistance

Ability of the dry film to withstand an average loss of less than the specified oil film thickness within a specified area when exposed to a specified wet scrub cycle (3.5)

Catatan 1: In ISO 11998, resistance to wet scrubbing is based on laboratory tests of 200 wet scrubbing cycles.
