Thermoplastics pipes - Determination of resistance to external blows - Round-the-clock method (ISO 3127:1994)

Cancels and replaces the first edition (1980). Specifies a method for the determination of the resistance to external blows of thermoplastics pipes of circular cross-section (round-the-clock method). This method is applicable to isolated batches of pipe tested at 0 °C.

Rohre aus Thermoplasten - Bestimmung der Widerstandsfähigkeit gegen äußere Schlagbeanspruchung - Umfangsverfahren (ISO 3127:1994)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Widerstandsfähigkeit von Rohren aus Thermoplasten mit kreisförmigem Querschnitt gegen äußere Schlagbeanspruchung fest. Dieses wird Umfangs¬verfahren (en: around-the-clock method) genannt.
Dieses Verfahren ist auf einzelne Rohrchargen, die bei 0 °C geprüft werden, anwendbar (es umfasst auch Informationen zu Probenahme aus der kontinuierlichen Rohrherstellung).
ANMERKUNG 1   Wenn eine Prüfung unter 0 °C erforderlich ist, wird eine Temperatur von −20 °C empfohlen.

Plastomerne cevi - Določanje odpornosti proti zunanjim udarcem - Metoda s postopkom rotiranja (round-the-clock method) (ISO 3127:1994)

Razveljavlja in nadomešča prvo izdajo (1980). Določa metodo za določevanje odpornosti na zunanje udarce plastomernih cevi s krožnim prerezom (metoda s postopkom rotiranja). Ta metoda se uporablja za posamezne serije cevi, ki se preskušajo pri 0 °C.

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 3127 was prepared by Technical Committee
lSO/TC 138, Plastics pipes, fittings and valves for the transport of fluids,
Subcommittee SC 5, Genera/ properties.
This second edition cancels and replaces the first edition (ISO 31279 980),
which has been technically revised.
