Corrosion Testing

Corrosion Testing and Corrosion Studies

Corrosion Studies and Corrosion Testing is undertaken by PERS  as per ASTM, DIN, or as per individual client requirements. PERS has an in-house team of industry-specific experts to provide corrosion consulting, advisory services on 
corrosion prevention and corrosion control services including materials selection in a laboratory or on-site inspection.

A wide variety of corrosion related tests is undertaken at PERS to determine the susceptibility to intergranular corrosion, pitting corrosion, stress corrosion cracking, etc. The range of instruments available to perform these tests is unrivaled in across geographies. PERS can also carry out testing under third party inspection agencies like LRS, TUV, DNV, ABS, BV among other inspection agencies.

PERS has added a fully automated avant-garde Salt spray testing facility. This test is extremely useful in analyzing the corrosion resistance properties of plating, coating, painted surfaces and materials that are used in corrosive environments.

PERS offers a comprehensive range of material testing services for corrosion problems that include:
