Quality as the Strategic Focus
Quality process is an integral part of everything Novatherm does. Quality action teams of Novatherm throughout the world are continually working to improve products, processes and procedures to better meet customer requirements.
We have learned and adapted many of the best practices of successful quality management systems to create our own Novatherm Quality System. There is no end for quality. Novatherm Quality System is designed to be a cycle:
Quality is engineered into Novatherm products during the entire manufacturing process. The three phases of quality control involve the incoming raw material, the pipe production, and the finished product. The combination of all three areas ensures that the final product will fulfill the requirements and meet the desired specifications.
Differential Scanning Calorimetry Test
It measures the temperatures (T) and heat flows (∆H) associated with transitions in materials as a function of time and temperature in a controlled atmosphere. DSC can be used to measure melting points, heats of melting, percent crystallinities, glass transition temperatures, crystallization times, and thermo-oxidative stabilities.
Oxidative Induction Time Test
Differential Scanning Calorimetry is for measuring the antioxidant properties of materials. It is used for evaluating the level of stabilization of the material. Performance of the specimen, longer the OIT value, better is the thermal oxidative stability of the material.
Melt Flow Rate Test
Melt flow index or MFI is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes. The method is described in the similar standards ASTM D1238 and ISO 1133.
Charpy Test
Impact resistance is the ability of a material to resist breaking under a shock loading. Standard test specimens prepared from Novatherm pipes are subjected to a pendulum-type impact load in accordance with ISO 15874 standards.
Heat Reversion Test
Pipes are subjected to thermal stresses inside a thermostatic chamber with continuous air circulation to observe shrinkage in accordance with ISO 15874 standards.
Hydrostatic Pressure Test
Novatherm pipes are subjected to pressure tests according to DIN 1988 and EN ISO 1167-1 standards to determine service life andobtain required information about mechanical characteristics of pipes. The long-term burst strength of pipes is determined by subjecting the pipes to constant internal pressure and observing time-to-failure data.
Thermal Stability Test
A method for developing long-term hydrostatic design stresses, defined as the estimated tensile stress in the wall of the pipe in the circumferential orientation due to internal hydrostatic pressure that can be applied continuously with a high degree of certainty that failure of the pipe will not occur. The long-term performance of thermoplastic pipe materials is evaluated by stresses calculated for a period of 50 years in DIN 8077 and DIN 8078 standards.
Dimensional Test
Pipe diameter, wall thickness, ovality, and length are measured on a regular basis to ensure their compliance with the prevailing specifications. The outside diameter and the wall thickness shall comply with ISO 15874 specifications.
Adhesion Test
Adhesion Test is used to measure the peeling strength of the binding layers between the internal and aluminum layers of Novatherm Pipes.
External Control
Beside the internal controls which are planned and maintained by qualified NOVATHERM technical departments, there are also periodic external controls carried out by independent international organizations like TÜV-NORD, SKZ, WRAS, AENOR, and Hygiene Institut. These controls include both product testing according to relevant standards and whole quality system controls. Therefore external controls are the main tools for us to ensure the highest quality products hence satisfying our customers’ expectations.
Locate and Trace Tools
Locate and trace tools make easier handling (H), loading (L), storing (S) and tracing (T) processes with visual locating and comprehensive feedback data.
