Testing, Certifications and Standards

MAIRA insulators are designed and manufactured to meet the requirements of following standards:

European Standards:

• SRCEI 61109/96;
• SRCEI 815/94;
• SRCEI 383- 1/96;
• SRCEI 383-2/ 96;
• SRCEI 273/94;
• SRCEI 168/97;
• SRCEI 507/96;
• SRCEI 71- 1/C1/97

ANSI (American) Standards

• C29.11-1989(1996);
• C29.12-1997 (2002);
• C29.13-2000;
• C29.17-2002;
• C29.18-2003.

All tests are carried out at ICMET Laboratory (Craiova, Romania), one of the leading European specialized testing and certification entities.

In addition, our Quality Management procedures include:

a) full traceability of all vendor parts, including quality certificates and test reports for each batch;
b) testing between different production phases (f. inst. testing the strength of the fiberglass rod – metal fitting junction before injection);
c) final product performance testing in specialized, certified laboratories.

The performances and characteristics testing procedures for MAIRA Insulators cover, as minimum requirements, following areas:
