SF6 Test Programs

Obtaining detailed SF₆ quality information by ALI’s ISO/IEC 17025 accredited gas laboratory is an easy, rapid and straightforward process using ALI’s SF₆ No-Haz recover & recycle “green” sampling & shipping kits.  With our No-Haz kits you do not need a hazmat-certified staff member to legally and properly ship your samples … a critical advantage for ALI customers.

These kits can be used for testing new SF₆ in cylinders or in-service SF₆ from gas insulated equipment (GIE).

Alternatively, customer cylinders or high pressure SF₆ sampling cylinders can be employed for testing when needed

We offer three basic types of SF₆ Analysis Programs:

• ASTM SF₆ Purity Program: Includes all ASTM-2472 tests associated with new or repurified SF₆ cylinders.
   
• Standard In-Service Program: Includes all tests associated with ASTM-2472 / IEC-376 program and tests for common SF₆ degradation products (ex. CF₄, SO₂, SOF₂, HF). CIGRE in-service limits are offered as guidelines for data interpretation.
   
• Advanced In-Service Program (used primarily for GIE failure diagnostics): Includes all tests associated with ASTM-2472 / IEC-376 program and tests for common SF₆ degradation products (ex. CF₄, SO₂, SOF₂, HF) plus several other known SF₆ degradation products that can assist in GIE failure mode investigations. CIGRE in-service limits are offered as guidelines for data interpretation.

We also offer on-site SF₆ sampling & shipping services.
