Dicht oder Nicht-Dicht, das ist bei Abwasserkanälen die entscheidende Frage. Undichte Schmutzwasserkanäle sind eine Belastung für das Grundwasser und gefährden damit auch die Versorgung mit hygienisch einwandfreiem Trinkwasser. Aus diesem Grund verlangen immer mehr Gemeinden eine Dichtheitsprüfung für privaten Anschlussleitungen. Aber auch das Risiko für Verstopfungen und Korrosion in den Rohren kann durch versickerndes Schmutzwasser entscheidend erhöht werden. Bei Neubauten, Umbauten oder nach der Ausführung teurer Kanal- Sanierungsmassnahmen wie Inliner oder Partliner wollen Sie sicher sein, dass die Rohre auch wirklich dicht sind. Unser Dichtheitsprüfsystem für Muffen- und Haltungsprüfungen mit Luft verfügt über geeichte Sensoren gemäss den gültigen Normen. Der Einsatz von Computern für die Dichtheitsprüfung verschafft uns und Ihnen einen optimalen Überblick über die Resultate, die als optisch ansprechendes Dichtheitsdiagramm ausgedruckt werden können. Ist das Kanalsystem sehr verwinkelt oder schlecht zugänglich kann der Nachweis für die Dichtheit auch über eine Wasserfüllprobe erstellt werden. Dichtigkeitsprüfung Vorgehen Dichtigkeitsprüfungen können entweder mit Luft oder mit Wasser durchgeführt werden. Die zu prüfende Haltung wird beidseitig mittels Absperrblase verschlossen, ebenfalls allfällige Seitenanschlüsse. Das Rohr wird dann bei definiertem Druck mit Luft oder Wasser befüllt und der Druckverlust elektronisch gemessen. Der maximal zulässige Druckverlust ist in allgemein gültigen Normen festgelegt, nämlich in SIA 190 für Hauptkanäle und SIA 190.203 (EN 1610) für Hausanschlüsse.

OECD 431 Test Guideline No. 431 In Vitro Skin Corrosion: Reconstructed Human Epidermis (RhE)Test Method Fast Project Execution: personal - competent - reliable --> contact@invitro-connect.com INVITRO-CONNECT GmbH offers various test strategies without animal testing for examining skin Corrosion: - OECD 431 - Human Skin Corrosion: "In Vitro OECD 431: Reconstructed Human Epidermis Test Method, in vitro Test - Skin Corrosion in the regulatory hazard classification and labeling context is defined as the production of irreversible damage to skin, generally evident as necrosis through the epidermis and into the dermis, following a defined chemical exposure. The In Vitro Skin Corrosion Test is an in vitro, non-animal test designed to identify those chemicals and mixtures capable of inducing skin corrosion (UN GHS Category 11), and in some cases to partially subcategorize corrosives into UN GHS Sub-Categories 1A or 1B and 1C (ie., the current test methods do not effectively discriminate between UN GHS Sub-Categories 1B and 1C). This test method is useful for regulatory classification and labeling of chemicals and mixtures, and depending upon the regulatory jurisdiction and framework the test results may be used as standalone or to support a weight of evidence approach. Since skin corrosion in vivo typically results from rapid chemical-induced cell damage, this test method provides a mechanistically-relevant measurement of cell viability in reconstructed human epidermis (RhE) tissues after a single topically-applied chemical treatment, relative to negative control-treated tissues. INVITRO-CONNECT has extensive expertise with a wide variety of reconstructed skin-based protocols. NOTE: Since this test method does not discriminate among any non-corrosive categories, a non-corrosive prediction by this test method should be followed up with a test for potential skin irritation, using any of the validated Skin Irritation Test (SIT) methods, including the In Vitro Skin Irritation Test using a Reconstructed Human Epidermis (RhE) Model.

Test Guideline No. 439 OECD 439 / in Vitro Skin Irritation Reconstructed Human Epidermis Test Method Fast Project Execution: personal - competent - reliable --> contact@invitro-connect.com INVITRO-CONNECT GmbH offers various test strategies without animal testing for examining Skin Irritation: - OECD 439 / Skin Irritation Test (SIT) in a Reconstructed Human Epidermis (RhE) Model - Skin Irritation in the regulatory hazard classification and labeling context is defined as the production of reversible damage to skin following a defined chemical exposure. The Skin Irritation Test (SIT) is an in vitro, non-animal test designed to identify those chemicals and mixtures capable of inducing moderate skin irritation (UN GHS Category 2 Skin Irritants1), and to discriminate UN GHS Category 2 Skin Irritants from UN GHS 3 Mild Skin Irritants as well as those not requiring classification for skin irritation potential. This test method is useful for regulatory classification and labeling of chemicals and mixtures, and depending upon the regulatory jurisdiction and framework the test results may be used as standalone or to support a weight of evidence approach. Since skin irritation in vivo typically results from chemical-induced cell damage and subsequent inflammatory cascade, this test method provides a mechanistically-relevant measurement of cell viability in reconstructed human epidermis (RhE) tissues after a single topically-applied chemical treatment, relative to negative control-treated tissues. Chemicals which reduce relative viability to ≤ 50% would be classified as an irritant (and a potential corrosive), while those which result in a relative viability > 50% would not be classified as a skin irritant in accordance with UN GHS Category 2. INVITRO-CONNECT GmbH has extensive expertise with a wide variety of reconstructed skin-based protocols. NOTE: Since this test method does not discriminate UN GHS categories 1 and 2, an irritant prediction by this test method should be followed up with a test for potential skin corrosion, using any of the validated corrosivity test methods. 1) Corrositex Membrane Barrier Time Monitor Corrosion Test Method and 2) In Vitro Skin Corrosion Test using a Reconstructed Human Epidermis (RhE) Model A variety of other protocols are available to evaluate for potential skin irritation to support product development, product stewardship, candidate formulation selection and other non-regulatory applications, and can provide a rank ordering of skin irritation potential. A variety of protocols allow for evaluation of mild formulations: 1) Time-to-Toxicity ET50 Screening protocol, and 2) Cytokine Expression Assay for Mild Products and for moderate to corrosive products and mixtures: 3) In Vitro Skin Irritation / Corrosion Screen.
