Textiles - Test methods for nonwovens - Part 8: Determination of liquid strike-through time (simulated urine) (ISO 9073-8:1995)

Provides a method for measuring the time of liquid (simulated urine) strike-through for nonwovens. Does not simulate in-use conditions for finished products.

Textilien - Prüfverfahren für Vliesstoffe - Teil 8: Bestimmung der Durchdringzeit von Flüssigkeiten (simulierter Urin) (ISO 9073-8:1995)

Dieser Teil von ISO 9073 legt ein Verfahren für die Messung der Durchdringzeit von Flüssigkeiten (simulierter Urin) für Auflagen aus Vliesstoff fest. Das Verfahren ist für Vergleiche zwischen unterschiedlichen VliesstoffAuflagen geeignet. Es simuliert keine Einsatzbedingungen für Endprodukte. Anmerkung 1: Diese Internationale Norm beschreibt ein Prüfverfahren speziell für Vliesstoffe.

Textiles - Méthodes d'essai pour nontissés - Partie 8: Détermination du temps de transpercement des liquides (urine artificielle) (ISO 9073-8:1995)

La CEI 61954:2011 définit les essais de type, les essais de production et les essais facultatifs des valves à thyristors utilisées dans les bobines d'inductance commandées par thyristors (TCR), les bobines d'inductance commutées par thyristors (TSR) et les condensateurs commutés par thyristors (TSC) qui font partie des compensateurs statiques de puissance réactive (SVC) pour des applications de système de puissance. Les exigences de la présente norme s'appliquent tant aux unités à valve unique (monophasées) qu'aux unités à valves multiples (polyphasées). Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Les définition des termes "niveau de thyristor", "section de valve", "électronique de base de valve", "niveaux de thyristors redondants" ont été clarifiées;
b) Les conditions pour les essais des sections de valves de thyristors à la place des thyristors complets ont été définies;
c) Une exigence a été ajoutée afin que, suite à un essai de test, si un niveau de thyristor a été court-circuité, alors le niveau défaillant puisse être restauré et cet essai de type répété;
d) La période de temps d'accroissement de la tension d'essai initiale de 50 % à 100 % pendant l'essai de type diélectrique en courant alternatif sur les valves TSC, TCR ou TSR, a été fixée à approximativement 10 s;
e) La durée de l'essai de tension U_ts2 pendant l'essai de type diélectrique c.a.-c.c. entre des bornes de valves TSC et la terre, ainsi que la durée de la tension d'essai U_tvv2 pendant les essais diélectriques entre valves TSC (pour les MVU uniquement) a été modifiée de 30 min  à 3 h;
f) Suppression de la référence au nombre d'impulsions par minute de décharge partielle périodique enregistrées pendant les essais diélectriques c.a.-c.c. sur les valves TSC et dépassant le niveau admissible.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each 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. IS0
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 IS0 9073-8 was prepared by Technical Committee
lSO/TC 38, Textiles.
IS0 9073 consists of the following parts, under the general title Textiles
- Test methods for nonwovens:
- Part 1: Determination of mass per unit area
- Part 2: Determination of thickness
- Part 3: Determination of tensile strength and elongation
- Part 4: Determination of tear resistance
- Part 7: Determination of bending length
- Part 8: Determination of liquid strike-through time (simulated urine)
- Part 9: Determination of drape coefficient
