Axiom Week: Day 1
FAQs, Myths, Fabrications & Misinformation about the Type C1 Purifier Axiom - Part 1
In May, 2015, the NSF/ANSI Standard 49 Joint Committee appointed a Task Group to address definitions within the standard. Definitions including those for the different types of Class II Biosafety Cabinets (BSC) are to be reviewed, updated and added to. In August, 2015 that Task Group determined that the Purifier Axiom will be designated something other than a Type A or B, and defined as such. Labconco has chosen to designate this a Type C1, pending final designation and definition by NSF.
The Axiom has already been listed by NSF’s testing laboratory to Standard 49 for both 4 and 6 foot options, in both 8 and 10 inch sash heights, and installed in both recirculating and ducted modes.
MYTH: NSF does not recognize the Type C1 designation.
TRUTH: During development of the Axiom – Labconco, concerned about the current definitions and this BSCs obvious divergence from them, requested NSF’s feedback. NSF approved the use of Labconco’s designation “Type C1” with the instruction to include in writing that any designation and/or definition of such was pending NSF’s formal adoption process.
MISINFORMATION: The Axiom is not an NSF listed Type A BSC nor a Type B BSC
TRUTH: From NSF Business Unit Manager, Maren H. Roush:
“As noted in the official NSF Listings online at http://info.nsf.org/Certified/Biosafety, Labconco models 30441, 30448, 30461 and 30468 do not fall entirely under the “A” or “B” cabinet type definitions in the 2012 version of NSF Standard 49. However, they were found to meet the materials, design, construction and performance requirements of NSF/ANSI 49-2012, and as such, were Certified by NSF International.
“Standard 49 allows for cabinets that vary in design, construction, or installation of accessory equipment, if appropriate tests and investigations indicate that the equipment is durable and reliable, can be cleaned and decontaminated, and performs in conformance to the Standard. The aforementioned Axiom models were tested by NSF International to Standard 49 in both recirculating mode and with direct exhaust.
“Additional tests that were performed on these Axiom models included smoke visualization above the directly exhausted section of the work surface and an evaluation of the cabinet’s ability to maintain inflow velocity in the event of an exhaust system failure (with the alarm function disabled).”
