Scratch Adhesion Tester NOVOTEST C1-5178
It is a device for determining the adhesion and resistance to damage by scratching. This device is designed for the analysis the resistance of the coating for scratching. The cutting unit with interchangeable indenters is pressing on the surface with load and moves to the predetermined distance.
In depending on of the testing and the applied load, the degree of penetration of the cutting unit into coating could be different, from the trace on surface to a total destruction of objects. Device determines the resistance of the coating for scratching.
Modern requirements to the quality of coatings include control the mechanical resistanceof coatings to damage. The one important criterion of its assessment is the hardness of the coatings.
Bending Coating Tester NOVOTEST BEND-M1519
The device measures the elasticity and strength of the coatings through bending the metal plate with tested coating around a set of cylindrical rods with diameters of rods from 2 mm to 32 mm (other diameters on request). The device applies to paints and specifies a method for determining the elasticity of the film during bending.
Bending Coating Tester NOVOTEST BEND-M1519 consist of the frame with fixed clamps for tested samples and a special mechanism for rounding plates around the rod with different diameters. Pre-prepared tested sample is placed between the clamps and securely fixed through the rotation of the handle. After that push the tested object to the top of rod through the rotation of the handle and produce bending the plate around the rod.
The method is consist in the determining the mínimum diameter of the cylindrical metal rod, after bending around it, the painted metal plate, does not get the mechanical destruction or delamination of single- or multi-layer Paint film. Flexibility is tested by rounding the tin plate with coating around the cylindrical rod with diameter from 2 to 32 mm. The flexibility value of coating with certain film thickness – is the smallest diameter of rod, when cracking does not occur.
Buchholz Coating Hardness Tester NOVOTEST BH-2815
Buchholz Coating Hardness Tester NOVOTEST BH-2815 is used for hardness measurements of coating’s using the indentation method (bevelled disc of stainless steel block with constant test load of 500g.).
The device is to be places on the coating for 30 seconds and the length of any subsequent indentation in the coating is to be measured using the graduated microscope. Using the conversion scale, user can get the result in Buchholz Indentation resistance units.
Erich Cupping Tester NOVOTEST SE-1520
Erichsen stamp is designed to determine the elasticity and strength of coatings with a bowl-shaped bend (hood coverage for the Erichsen) in compliance to ISO 1520.
The device is designed to determine the strength of coating during indentation of a spherical tip of the punch of 20 mm diameter to the coated test sample, which position is secured on the matrix with internal diameter of 27 mm.
This method is an effective of determining of the quality of coating, it allows simultaneously to evaluate the strength, adhesion, and elasticity of the tested coating.
Erichsen Cupping Tester NOVOTEST SE-1520 allows user to accurately measure the strength of coating of the tested product on which static and Dynamic loads affect during further operation.
The device allows user to measure elasticity, strength and durability of paint and varnish coatings and its resistance to stretching, cracking, peeling out of the metal surface by pressing the punch with a spherical tip on a certain depth.
Impact Tester NOVOTEST STRIKE UNIVERSAL
Impact Tester NOVOTEST STRIKE UNIVERSAL has a multipurpose design and consists of a stand (with a pipe fixed to it with a scale and a clamping device) and an impact device according to the required standard. An impact device, as a rule, consists of a striker, clutch and anvil, the dimensions of which are specified in the corresponding standard. There can be an unlimited number of such shock devices in the delivery set of the device – therefore it is possible to test according to any number of standards.
Impact Tester NOVOTEST STRIKE-U4219
Impact Tester NOVOTEST STRIKE-U4219 is intended for testing the strength of coatings upon impact on pipelines during their installation and operation. NOVOTEST STRIKE-U4219 allows testing directly on the pipeline and does not require the manufacture of samples.
Advantages
The device is mounted on three adjustable feet-screws, so NOVOTEST STRIKE-U4219 can be installed on a flat surface (in the case of testing samples), and directly on a pipe of any diameter.
The impact test NOVOTEST STRIKE U4219 is made of structural steel and coated with powder paint, which guarantees its durability and adaptability to operation in difficult field conditions.
Pencil Hardness Tester NOVOTEST PH-3363
The instrument is designed to determine the hardness of coatings by pencil leads in compliance with: ASTM D 3363, ECCA T4, EN 13523-4, ISO 15184:2012, JIS K 5600-5-4.
Application
The instrument is widely used for hardness testing of powder and liquid paint coatings. For high accuracy of the results, the lead of pencil should be sharpen under 90° angle.
The tests begin with the softest pencil leads. If after applying there is no any signs of damage on the tested coating, user will have to repeat the test with one grade harder pencil leads.
The MAX hardness value of pencil leads, that leaves no any traces of destruction on the coating, is hardness value of tested coating (for example: 3H, 2H, H, HB, B, 2B, etc.).
Scratch Hardness Coating Tester NOVOTEST SH-1518
Scratch Hardness Coating Tester NOVOTEST SH-1518 (ball type) is used for hardness testing of coatings (paint, mastic, plastic and others) through determining the hardness resistance to indentation of the ball tip diameter of 1 mm.
The device can be used on uneven surfaces, surfaces with curvature and limited sizes. NOVOTEST SH-1518 has lightweight and can be carried in the pocket, which allows users to use it even during manufacturing processes. User can set the load force through changing the spring tension and secure it with locking screws.
Bending Coating Tester NOVOTEST BEND-H1519
The instrument measures the elasticity, flexural strength of coatings through rounding the tested sample on the set of cylindrical rods which diameters are from 1 mm to 20 mm.
The method consist in the determining the minimal diameter of the cylindrical metal rod, after bending around which, the coating of painted metal plate, does not get the mechanical destruction or de-lamination of single- or multi-layer paint film.
Bending Coating Mandrel Tester NOVOTEST BEND-H1500
The instrument measures the elasticity, flexural strength of coatings through rounding the tested sample on the set of cylindrical rods which diameters are from 6 mm to 25 mm.
