introduction
ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented on that committee. International governmental and non-governmental organizations liaising with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.
International standards are drafted in accordance with the rules given in Part 3 of the ISO/IEC Directive.
The draft international standard adopted by the Technical Committee will be circulated to the member bodies for voting. Publication as an international standard requires approval by at least 75% of member institutions.
You are advised that some elements of this part of ISO 6744 May be the subject of a patent right. ISO is not responsible for identifying any or all such patents.
The international standard ISO 6744-4 was developed by Technical Committee ISO/TC 35, Paints and Varnishes, Subcommittee SC 10, Test Methods for adhesives for Paints and varnishes.
ISO 6744-4-1999 Adhesive alkyd resins for paints and varnishes – Part 4: Determination of fatty acid content
Together with other parts (see below), this part of ISO 6744 cancels and replaces the technically revised ISO 6744:1984.
ISO 6744 consists of the following parts, under the general heading Paints and varnishes binders – alkyd resins:
– Part 1: General test methods
– Part 2: Determination of phthalic anhydride content
– Part 3: Determination of unsaponifiable matter content
– Part 4: Determination of fatty acid content
1 Range
This part of ISO 6744 specifies the method for determining the fatty acid content of alkyd resins. It is always used in conjunction with ISO 6744-2 and -3, which contain the above analytical steps.
It does not apply to modified alkyd resins (see 3.2 of ISO 6744-1:1999) or resins containing benzoic acid.
