Nonwoven geotextiles are used in many geomembrane projects as protection or cushioning layers. Placed between the geomembrane and surfaces such as stone, aggregate or concrete, these materials help reduce the risk of localized damage. Evaluating their quality requires more than measuring mass per unit area: tensile strength, strain, tear resistance, puncture resistance and ultraviolet durability…

AHP PLASTIK MAKINA is developing a new generation software platform for industrial quality control, laboratory testing, measurement, data acquisition, process monitoring and laboratory automation. The AHP QC Lab Platform is designed around a simple concept: One flexible…
Introduction ASTM F2418 – Standard Specification for Polypropylene (PP) Corrugated Wall Stormwater Collection Chambers establishes material requirements, dimensional requirements, mechanical performance criteria, test procedures, sampling rules, acceptance criteria, and marking requirements for polypropylene underground stormwater chambers. These chambers are open-bottom, arch-shaped thermoplastic structures designed for underground collection, detention, and retention of stormwater. Typical applications include:…
Introduction The CSA B184 Series:22 – Polymeric Subsurface Stormwater Management Structures establishes material, structural, dimensional, mechanical, long-term performance, testing, and quality-control requirements for polymeric structures used in subsurface stormwater management systems. The standard is particularly applicable to stormwater chambers manufactured from: The standard is divided into several parts: A major aspect of this standard is…
1 ScopeThis document specifies two general test methods, Method A and Method B, for determining the impact strength of notched and unnotched specimens cut from thermoplastic pipes for the transport of liquid and gaseous media: 5 Test apparatus5.1 Pendulum impact-testing machineThe principles, characteristics and verification of a suitable pendulum impact-testing machine shall conform to ISO…
10.7 Tensile test10.7.1 Conduit systems declaring tensile strength shall be tested as follows:A sample of conduit and two conduit fittings or terminating conduit fittings are assembled in accordance with the manufacturer’s instructions so that the overall length is approximately 300 mm. The assembly is subjected to a uniformly increasing tensile force reaching the value given…
Apparatus3.1 Pressurizing device, capable of applying and regulating the water pressure in the test piece in asinusoidal or trapezoidal form between pressure limits as specified in the reference standard.3.2 Pressure measurement device, capable of measuring the water pressure in the test piece to an accuracy of ±5 %. The device measurement shall be capable of…
How to specify the laboratory hydraulic hot press, mould, force capacity, temperature control and cooling system for technically defensible specimen preparation. Machine-selection conclusion: For ISO 293:2023, the decisive press requirements are not simply “a hot press”. The system must deliver at least 12 MPa cavity pressure, hold the specified pressure within ±10%, heat the platens…
Mechanical side action grips feature a dual-acting screw design. Mechanical screw side action grips provide an efficient method for holding test specimens in a wide range of tensile testing applications. Mechanical screw action grips are also the most affordable grip in their force class because they depend on the operator to open and close them….
