Elcometer 3086 Motorized Pencil Hardness Tester About

Elcometer 3086 Motorised Pencil Hardness Tester provides a rapidmethod for determination of the comparative scratch resistance and hardnessof a coating.

This test is known as the Wolff-Wilborn method and is fully described in BS3900 - E19, ISO 15184 and ASTM D 3363 -92a. A coated panel is placed on afirm horizontal surface and the pencil lead is held firmly against the coating,point way from the operator, at a 45 angle. The Pencil Hardness Testertravels across the coating sample. The hardness of the pencil lead is increaseduntil one or both of the following defects mark the coating:

Plastic deformation; a permanent indentation in the paint surface withoutcohesive fracture.
Cohesive fracture; the presence of a visible scratch or rupture in thesurface of the paint film, material having been removed from the paint film.(Above definitions are taken from ISO 15184.)

Note: For the ASTM method D 3363, the test is started using the hardest pencil

lead and continued down the scale of hardness to determine the two end points:

The pencil lead that will not cut or gouge the coating.
The pencil lead that will not scratch the coating.

The Elcometer 3086 is motor driven; this helps to eliminate any variation in testresults which may occur due to operator technique. Your Pencil Hardness Tester uses standard black leads, and is supplied with 14 grades of lead, covering 6H (very hard) to 6B (very soft).

Elcometer 3086 Motorised Pencil Hardness Tester can be used inaccordance with the following National and International Standards:

ASTM D 3363, BS 3900-E19, EN 13523-4 supersedes ECCA T4, ISO 15184,
JIS K 5600-5-4.

FAQs of Elcometer 3086 Motorized Pencil Hardness Tester:

Q: How does the Elcometer 3086 Motorized Pencil Hardness Tester operate?

A: This tester utilizes an automatic, motorized mechanism that ensures a uniform testing force between 0 and 10 N, reducing human error associated with manual testing. Simply set the force, load the pencil, and the machine will conduct the scratch test automatically.

Q: What is the primary application of the Elcometer 3086 tester?

A: The main application of this instrument is to measure pencil hardness or scratch resistance on coated substrates, such as paints, varnishes, and plastics, ensuring coatings meet specified quality standards.

Q: Where is this pencil hardness tester commonly used?

A: It is widely used in quality control laboratories, paint manufacturing units, automotive plants, and any environment where painted or coated surfaces require hardness assessment. In India, it is available through reputable distributors, suppliers, and traders.

Q: What is the process for conducting a pencil hardness test with this machine?

A: To perform a test, install the appropriate pencil, select the desired test force (from 0 N to 10 N), and allow the device to automatically carry out the scratch test. The hardness rating is based on the hardest pencil that does not scratch the surface, following standardized procedures.

Q: What benefits does the automatic operation offer compared to manual pencil hardness testers?

A: The motorized model provides enhanced repeatability and consistency by removing operator-related variation. This leads to higher accuracy and reliability in your hardness measurements, crucial for quality assurance and compliance.

Q: When is the ideal time to use the Elcometer 3086 during the coating process?

A: It is best to use this tester after the coated surface has fully cured, ensuring accurate assessment of the coatings scratch resistance and compliance with industry standards.
