Tester cu dorn cilindric pentru testarea rezistentei la indoire alungirii elasticitatii peliculelor

Conform standarde ISO 1519:2011, ASTM D522 si DIN 53152

Dispozitiv pentru testarea elasticitatii, aderentei si elongatiei vopselei uscate de pe suprafete metalice; permite indoirea placutelor de testare cu grosimi diferite (functie de materialul placutei) utilizand 12 dornuri cilindrice cu diametre diferite.
Prevazut cu un maner, ajustabil pe inaltime si o menghina glisanta pentru proba; instrumentul poate fi adaptat la diametrul dornului utilizat.
Probele cu o latime de pana la 70 mm si 80 mm sau cu o lungime de 100 mm (pentru un dorn cu diametrul de 2 mm, respectiv 32 mm) sunt perfect indoite pe dornuri descrescatoare pana cand se observa crapaturile

Cylindrical Mandrel Tester

Complies with ISO 1519:2011, ASTM D522 and DIN 53152 Standard

Application

Used to assess the resistance of a coating of paint, varnish or related product to cracking and/or detachment from a metal or plastic substrate when subjected to bending round a cylindrical mandrel under standard conditions.
This tester consists of three PVC rolls wich are arranged side by side and run on pivoting bearings.
Thus, the coating is not exposed to damge or shear stress during the test.
The test can be carried out:
- either as a "pass/fail" test, by carrying out the test with a single specified size of mandrel, to assess compliance with a particular requirement;
- or by repeating the procedure using successively smaller mandrels to determine the diameter of the first mandrel over wich the coating cracks and/or becomes detached from the substrate.

Technical data

- Latest and humanization design, convenient and quick to operate
- 12 pcs stainless steel mandrels with different diameters of: 2; 3; 4; 5; 6; 8; 10; 12; 16; 20; 25 and 32 mm
- All mandrels are machined precisely by high hardness stainless steel, 2mm and 3mm mandrels are done by hardening treatment, it won’t be deformed even bend the thick test panels
- Suitable test panels size:
• Length 120mm .. 150 mm;
• Widith ≤80 mm;
• Thickness ≤1.0 mm
*Comes with Calibration Certification
