Textile-glass-reinforced plastics - Prepregs, moulding compounds and laminates - Determination of the textile-glass and mineral-filler content - Calcination methods (ISO 1172:1996)

Gives two calcination methods for the determination of the textile-glass and mineral-filler content of glass-reinforced plastics. Method A is used for the determination of the textile-glass content when no mineral fillers are present; method B is used when both components are present. Replaces the first edition.

Textilglasverstärkte Kunststoffe - Prepregs, Formmassen und Laminate - Bestimmung des Textilglas- und Mineralfüllstoffgehalts - Kalzinierungsverfahren (ISO 1172:1996)

Diese Internationale Norm legt zwei Kalzinierverfahren zur Bestimmung des Textilglas- und Mineralfüllstoffgehalts von glasfaserverstärkten Kunststoffen fest: Verfahren A: zur Bestimmung des Textilglasgehalts, falls keine Mineralfüllstoffe vorhanden sind. Verfahren B: zur Bestimmung des Textilglas- und Mineralfüllstoffgehalts, wenn beide Bestandteile vorhanden sind.

ISO 1172:1996(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 1172 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and rehforcement fibres. This second edition cancels and replaces the first edition (ISO 1 172:1975), which has been technically revised (an additional method, method B, has been included and the annex, which concerned the estimation of the Standard deviation, has been replaced by annex A describing an alternative method of separating chopped glass fibre from mineral filier). Annex A of this International Standard is for information only. 0 ISO 1996 All rights reserved.

INTERNATIONAL STANDARD @ ISO ISO 1172:1996(E) Textile-glass-reinforced plastics - Prepregs, moulding compounds and laminates - Determination of the textile-glass and mineral- filler content - Calcination methods WARNING - This International Standard does not give details of the precautions that should be taken to meet health and safety requirements. The test methods described require the use of high temperatures and concentrated acids. lt is the responsibility of the User of this International Standard to follow the appropriate health and safety procedures. 1 Scope This International Standard specifies two calcination methods for the determination of the textile-glass and mineral- filier content of glass-reinforced plastics: Method A: for the determination of the textile-glass content when no mineral fillers are present. Method B: for the determination of the textile-glass and mineral-filler content when both components are present. This International Standard is applicable to the following types of material: - prepregs made from yarns, rovings, tapes or fabrics; - SMC, BMC and DMC moulding compounds; - textile-glass-reinforced thermoplastic moulding materials and granules; - filled or unfilled textile-glass laminates made with thermosetting or thermoplastic resins. The methods are not applicable to the following types of reinforced plastic: - those containing reinforcements other than textile glass; - those containing materials which do not completely burn off at the test temperature (for example, those based on Silicone resin); - those containing mineral fillers which degrade at temperatures below the minimum calcination temperatute. For these materials, ISO 1 1667, Fibre-reinforced plastics - Maulding compounds and prepreg
