Test Duration
Test time is the time during which a test force acts on an indenter. It is specified in standards to account for viscoelastic effects and creep influences.
Physicochemical Mechanism of Action
The test time is the time during which a specific force is applied to an indenter. This time is important because it affects viscoelastic effects and creep, which influence the material's behavior under load.
Metallurgical Relevance & Welding Risks
When testing weld quality, the test time is critical. Too short a test time can give inaccurate results because the material may not fully settle. Too long a test time can cause unnecessary delays and possible damage to the indenter.
Workshop Practice & Procedures
The exact test time is specified in the relevant standards. You have to stick to that time to get reliable results. Example: For the penetration test per EN 10204-3, the test time must be at least 5 seconds.
