Plastics piping systems - Piping systems for underground drainage and sewerage - Test method for resistance to combined temperature cycling and external loading
This standard specifies two methods for testing components or joints for plastics piping systems intended for use in underground drainage and sewerage systems for their resistance to deformation and leakage when subjected to sustained external loading in conjunction with the passage of hot water. Method A involves cycling, by passing hot water and cold water alternately, and is applicable to pipes and associated fittings having a mean outside diameter dem <= 190 mm.
Kunststoff-Rohrleitungssysteme - Erdverlegte Abwasserkanäle und -leitungen - Prüfverfahren zur Bestimmung der Widerstandsfähigkeit gegen Temperaturwechsel und gleichzeitige äußere Belastung
Diese Norm beschreibt zwei Verfahren zur Prüfung von Bauteilen oder Verbindungen für Kunststoff-Rohrleitungssysteme, die in erdverlegten Abwasserkanal und -leitungssystemen verwendet werden, auf ihre Verformungsbeständigkeit und Dichtheit bei anhaltender äußerer Belastung in Verbindung mit dem gleichzeitigen Durchlauf von heißem Wasser. Verfahren A umfaßt die Temperaturwechselbeanspruchung durch abwechselnden Durchlauf von heißem und kaltem Wasser, und ist anwendbar für Rohre und dazugehörige Formstücke mit einem Nennaußendurchmesser dem <= 190 mm.
Systemes de canalisations en plastique - Systemes de canalisations pour assainissement enterré - Méthode d'essai pour la résistance a un cycle de températures et de charge externe combinés
Cette norme spécifie deux méthodes d'essai de tubes et de raccords ou d'assemblages de systemes de canalisations en matieres plastiques pour assainissement enterré pour vérifier leur résistance a la déformation et aux fuites lorsqu'ils sont soumis a une charge extérieure permanente conjuguée avec le passage d'eau chaude.
La méthode A qui implique un cycle thermique, avec passage alterné d'eau chaude et d'eau froide, est applicable aux tubes et raccords associés de diametre extérieur moyen dem L 190 mm.
La méthode B, qui implique le seul passage d'eau chaude, sauf dans des intervalles spécifiés pour le mesurage de la déformation interne, est applicable aux tubes et raccords associés de diametre extérieur moyen 190 mm < dem L 510 mm.

box loading procedure;— changes in box design.The material-dependent parameters and/or performance requirements are incorporated in the System Standard(s)concerned.Annex A, which is informative, gives recommended requirements.This standard includes a Bibliography.This standard is one of a series of standards on test methods that support System Standards for plastics pipingsystems and ducting systems.SIST EN 1437:2003

Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).ISO 48 Rubber, vulcanized or thermoplastic ¾ Determination of hardness (Hardness between 10 IRHD and100 IRHD) (including ISO 48:1994/Amd 1:1999)3 PrincipleA test piece comprising a pipe or an assembly of pipe(s) and fitting(s) is placed on a 100 mm gravel bed andcovered with gravel to 600 mm above the crown of the pipe confined by a box of specified dimensions.
Dependingon the nominal size of the largest pipe or joint under test, a constant vertical load is applied via the gravel andeither a specified number of cycles of hot and cold water or just hot water is passed through the test piece. Thedeformation of the test piece as indicated by vertical deflection or internal diametric compression is measured.For sizes having a mean outside diameter dem £ 190 mm, hot and cold water is passed through the test piece andair may be blown through the test piece during the intervals between stages (Method A).For pipes with a mean outside diameter 190 < dem £ 510 mm a constant flow of hot water is passed through thetest piece (Method B).Vertical deflection of the test piece is measured. The test piece is checked at the end of the test for cracking, forlocal deflection in the bottom of the main channel and for leakage at the joints.NOTE It is assumed that the following parameters are set by the standard making reference to this standard:a)
if appropriate, the limits of the temperature of the water flowing out (see 7.2.2);b)
if appropriate, the duration of the flow (see 7.2.2);c)
the percentage, x, of di for the calculation of the diameter of the hard ball, in accordance with 7.3.3.SIST EN 1437:2003
