introducere
ISO (Organizația Internațională pentru Standardizare) este o federație globală a asociațiilor naționale de standardizare (organismele membre ISO). The development of international standards is carried out through ISO technical committees. Fiecare instituție membră interesată de un subiect pe care a fost înființat un comitet tehnic are dreptul de a fi reprezentată în respectivul comitet. Organizațiile internaționale guvernamentale și neguvernamentale care au legătură cu ISO sunt, de asemenea, implicate în această activitate.

Draft international standards adopted by technical committees are circulated to member bodies for approval before being accepted as international standards by the ISO Council.

Standardul internațional ISO 787/1 was developed by the Technical committee ISO/TC 35 (Vopsele și lacuri) and distributed to member institutions in June 1980.

ISO 787-1-1982 Metode generale de testare pentru pigmenți și materiale de umplutură – Parte 1: Comparația culorilor pigmentului

It has been approved by the following national member bodies:

The member bodies of the following countries expressed their disapproval of the document on technical grounds:

ISO 787-1-1982 Metode generale de testare pentru pigmenți și materiale de umplutură – Parte 1: Comparația culorilor pigmentuluiFranţa

Germania, F.R.

This international standard eliminates and replaces ISO Recommendation R 787/1-1968, which constitutes a technical revision.

The purpose of this standard is to establish a common set of test methods for pigments and fillers that are applicable to all or many individual pigments and fillers for which specifications may be required. În acest caz, a cross-reference to the general method should be included in the international standard relating to the pigment or filler, with an indication of any detailed modifications that may be required in view of the particular properties of the product concerned.

The ISO/TC 35 Technical Committee, Vopsele și Lacuri, decided that all common methods should be published as part of a single international standard when available to emphasize the relationship of each method to the entire series.

ISO 787-1-1982 Metode generale de testare pentru pigmenți și materiale de umplutură – Parte 1: Comparația culorilor pigmentului

The Technical Committee also decided that if two or more procedures are widely used to determine the same or similar properties of pigments or fillers, there is no objection to the inclusion of more than one of these procedures in the ISO series. În acest caz, however, you need to clearly state which method will be used in the specification and which method is used in the test report.

Published portions of the series are as follows:

Parte 1: Comparația culorilor pigmentului

Parte 2: Determinarea substanţelor volatile la 105°C

Parte 3: Determinarea substanțelor solubile în apă – hot extraction method

Parte 4: Determination of acidity or alkalinity of water extracts

Parte 5: Determination of oil absorption value

Parte 7: Determination of residue on screens – Water method – Manual procedure

Parte 8: Determinarea substanțelor solubile în apă – Cold extraction method

ISO 787-1-1982 Metode generale de testare pentru pigmenți și materiale de umplutură – Parte 1: Comparația culorilor pigmentului

Parte 9: Determinarea pH-ului suspensiilor apoase

Parte 10: Determinarea densității – Metoda sticlei cu greutate specifică

Parte 11: Determination of compaction volume and apparent density after compaction

Parte 13: Determination of water-soluble sulfates, chlorides and nitrates

Parte 14: Determination of the resistivity of water extracts

Parte 15: Comparison of light fastness of similar types of colored pigments

Parte 16: Relative coloring force (or equivalent coloring value) și

Use automatic Muller to restore the color of linseed forest oil

Parte 17: Comparison of flash power of white pigments

Parte 18: Determination of residue on screens – water method – mechanical flushing procedure

Parte 19: Determination of water-soluble nitrates – salicylic acid method

Parte 20: Comparison of dispersability – Oscillation oscillation method

Parte 21: Comparing the thermal stability of pigments using baking media

Chapter 22 Comparison of the resistance of pigments to osmosis

Parte 23: Determinarea densității (removal of ensnared air by centrifuge)

Parte 24: Determination of the relative coloring power of colour pigments and the relative scattering power of white pigments – photometric method

0 Introducere
This document is part of ISO 787 “Common Test Methods for pigments and fillers”. ISO/R 787/1 was published in July 1968. The difference between this revision and the 1968 edition is this

A) The color comparison is performed using the procedure described in ISO 3668, și

b) No adhesive is specified.

1 Scope and field of application
1.1 Această parte a ISO 787 specifies a common test method for comparing the color of colored pigments with the color of agreed samples.

1.2 Any of the procedures described in Article 6 are acceptable, but the method using the automatic Muller is the reference method.

ISO 787-1-1982 Metode generale de testare pentru pigmenți și materiale de umplutură – Parte 1: Comparația culorilor pigmentului

Note that when this general approach is applied to a given pigment, the international standard relating to that pigment should include only a cross-reference to that pigment and indicate any detailed modifications that may be required in view of the particular properties of the material concerned. A special method of color comparison should be specified only if the procedure given in this general method is not applicable to a particular material.
