panimula
ISO (International Organization para sa Standardisasyon) ay isang pandaigdigang alyansa ng mga pambansang pamantayan katawan (Mga katawan ng miyembro ng ISO). Ang pagbuo ng mga internasyonal na pamantayan ay karaniwang isinasagawa sa pamamagitan ng ISO teknikal na komite. Ang bawat institusyon ng miyembro na interesado sa isang paksa kung saan itinatag ang isang teknikal na komite ay may karapatang kumatawan sa komiteng iyon. Ang mga internasyonal na organisasyon ng pamahalaan at di pamahalaan na nakikipag ugnayan sa ISO ay kasangkot din sa gawaing ito. ISO ay gumagana nang malapit sa International Electrotechnical Commission (IEC) sa lahat ng bagay ng electrical standardization.

International pamantayan ay drafted alinsunod sa mga patakaran na ibinigay sa Bahagi 3 ng Direktiba ng ISO / IEC.

Ang draft international standard na pinagtibay ng Technical Committee ay ipapakalat sa mga miyembro ng mga katawan para sa pagboto. Ang paglalathala bilang isang internasyonal na pamantayan ay nangangailangan ng pag apruba ng hindi bababa sa 75% ng mga miyembrong institusyon.

ISO 6744-1-1999 Adhesive alkyd resins para sa mga pintura at varnishes – Bahagi 1: General test methods

You are advised that some elements of this part of ISO 6744 May be the subject of a patent right. Ang ISO ay hindi mananagot para sa pagtukoy ng anuman o lahat ng naturang patente.

The international standard ISO 6744-1 was developed by Technical Committee ISO/TC 35, Mga Pintura at Varnishes, Subcommittee SC 10, Test Methods for adhesives for Paints and varnishes.

Together with other parts (see below), this part of ISO 6744 cancels and replaces the technically revised ISO 6744:1984.

ISO 6744 binubuo ng mga sumusunod na bahagi, under the general heading Paints and varnishes binders – alkyd resins:

– Bahagi 1: General test methods

– Bahagi 2: Pagpapasiya ng nilalaman ng phthalic anhydride

– Bahagi 3: Pagpapasiya ng nilalaman ng unsaponifiable matter

– Bahagi 4: Determination of fatty acid content

1 Saklaw
Ang bahaging ito ng ISO 6744 describes a general test method for alkyd resins used in paints, varnishes and similar products. It is also suitable for solutions and similar preparations made from alkyd resins that are intended to be used as adhesives for paints and varnishes.

The test method for individual alkyd resins shall be agreed upon by the parties concerned.

3 Mga tuntunin at kahulugan
For this part of ISO 6744, Ang mga sumusunod na termino at kahulugan ay nalalapat.

3.1 alkyd resin

A synthetic resin produced by polycondensation of polyacids and fatty acids (o mga langis) with polyols

3.2 Modified alkyd resin

ISO 6744-1-1999 Adhesive alkyd resins para sa mga pintura at varnishes – Bahagi 1: General test methods

Alkyd dagta, modified to obtain specific properties, such as with rosin acid, phenolic resin, vinyltoluene, styrene, isocyanate, polyamide or acrylic, epoxy resin or silicone compounds

Tala 1: Alkyd resins based on tall oil fatty acids containing no more than 4% abietic acid are considered “alkyd resins” and not “modified alkyd resins”.
