Product certifications

OSO spends more resources on ensuring that our products surpass safety and performance requirements than what is set out in The Building Regulations and Standards. Stress and performance tests on all products and components ensure the integrity and estimated life of the product. In-depth quality control (IQC) is carried out on all critical components, and continuous quality control and control measurements are made in the production process (PQC). Pressure tests with 1.5 x design pressure, electrical final control and testing (OQC) are performed on all products. The end result is the well-known OSO quality, which has shown outstanding life expectancy for less than 50 years.
