Testing

Nowadays, customers are more concerned about the quality of the products in comparison to any other factor. Owing to this reason, the industries are now emphasizing more on the quality variable to get themselves a noteworthy place in the competitive market.

At Nhat Nam Mechanical, we have a specialized team that strictly monitor each and every step in the production process to make sure that the sheet metal components are accurately welded as well as fabricated. If in case there is any fault found, the same is rectified instantly to achieve efficiency in operations.

The types of testing differ mainly in the machinery and the property of the material being tested. Some of the most popular techniques include tensile, fatigue, hardness, corrosion resistant. In order to understand the limits of material deformity before any stress or breakage exhibits, these tests are performed under controlled conditions for more accurate results.

In-house testing

Fatigue Test: Fatigue testing is done under a cyclical load that constantly adds stress to the material. This is done at a certain frequency or alternating load tests in order to measure tension or compression.
Tensile Test: By definition, tensile is defined as the capability of a material to become stretched or drawn out until cracks or stresses begin to show. Another more common term is “tensile strength” which is the resistance of breaking under impacts or stresses. This term is used to describe the limit at which steel or any ductile material transforms from temporary elasticity to permanent deformation.
Hardness Testing: Most mild steel or low carbon steel sheet metals that are 1.5 millimeters in thickness will most likely have a Rockwell B hardness rating. Rockwell hardness is simply the measuring range that determines the resistance of a material to permanent deformity and penetration by another material.
The salt spray test (or salt fog test): is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.

BIFMA/ANSI standard

ANSI/BIFMA put in place common standards for furniture products meant for use in a commercial office environment. Testing facilities that adhere to BIFMA protocols test office furniture durability, structural performance, and safety. The tests include anticipation of product misuse.

RoHS (Restriction of Hazardous Substances) certification services

Any business that sells applicable electrical or electronic products, equipment, sub-assemblies, cables, components, or spare parts directly to RoHS-directed countries, or sells to resellers, distributors or integrators that in turn sell products to foreign countries, is impacted if they utilize any of the restricted 10 hazardous materials.

Nhat Nam gives our customer a competitive advantage by partnering with third party RoHS Certification, providing sound traceability systems and strict enforcement of due diligence policies. Every step of the way to establish a detailed product file upon application that contains:
