All blowers manufactured by NS are verified annually for design and production technology compliance under ISO 9001 and ISO 14001.

Testing is conducted at specialized facilities that comply with international standards such as KS, ISO, ASME. Equipment calibrated according to KOLAS(Korea Laboratory Accreditation Scheme) and LabVIEW monitoring software are used for precise performance evaluation.

Tests are conducted in the presence of the customer, during which numerical data related to the specified performance and operating range are collected and provided as official documentation.

If the customer is unable to attend the test, experienced NS engineers will conduct the test on their behalf. The results will be provided in an NS-certified document, signed by the responsible engineer, and limited to the test items selected by the customer.
