Biosafety Cabinetry

“Der Alchemist” / Max Fuhrmann

NSF International develops a standard for one of the centerpiece safety technologies for a large revenue driver in research universities. The landing page for its biosafety cabinetry product, installation, operation and maintenance standard is linked below:

NSF 49 Biosafety Cabinetry.

From the project prospectus:

This Standard applies to Class II (laminar flow) biosafety cabinetry designed to minimize hazards inherent in work with agents assigned to biosafety levels 1, 2, 3, or 4. It also defines the tests that shall be passed by such cabinetry to meet this standard. NSF 49 includes basic requirements for the design, construction, and performance of biosafety cabinets that are intended to provide personnel, product, and environmental protection; reliable operation; durability and structural stability; cleanability; limitations on noise level; illumination; vibration; and motor/blower performance.

This equipment class is the centerpiece of many research laboratories and is a multidimensional risk aggregation so NSF 49 needs to move swiftly and is listed as an ANSI Continuous Maintenance product. You can track the action at the link below:

NSF typically uploads its live public consultation notices on ANSI Standards Action; one of the most recent on Page 11 of link below:

We maintain all NSF International titles on the agenda of our Laboratory and Risk teleconferences and, because NSF runs its standards suite continuously, most of its titles are on our Nota Bene teleconferences. See our CALENDAR for the next online meeting; open to everyone

Sizing of Stand-Alone Photovoltaic Systems

This recommended practice provides a procedure to size a stand-alone photovoltaic system. Systems considered in this document consist of PV as the only power source and a battery for energy storage. These systems also commonly employ controls to protect the battery from being over- or undercharged, and may employ a power conversion subsystem (inverter or converter). The issues of array utilization, battery-charge efficiency, and system losses are also considered in terms of their effect on system sizing. This recommended practice is applicable to all stand-alone PV systems where PV is the only charging source. This document does not include PV hybrid systems nor grid-connected systems. The hybrid systems referred to in the preceding sentence are off-grid but have multiple energy sources such as diesel generator, solar PV, and wind. This document is intended to be used in conjunction with IEEE Std 1013-2019 Recommended Practice for Sizing Lead-Acid Batteries for Stand-Alone Photovoltaic (PV) Systems. This recommended practice does not include the sizing of the system controller, inverter, wiring, or other system components.

Conformance

Health Level Seven International (HL7), founded in Ann Arbor, Michigan in 1987, is a not-for-profit, ANSI-accredited standards developing organization dedicated to providing a comprehensive framework and related standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery and evaluation of health services. HL7 is supported by more than 1,600 members from over 50 countries, including 500+ corporate members representing healthcare providers, government stakeholders, payers, pharmaceutical companies, vendors/suppliers, and consulting firms.

HL7 runs an outstanding content management system for its best practice titles linked below:

HL7 Standards – Master Grid

Like many consensus product developers with a continuous maintenance process, it has developed its own proprietary user interface.

Today we include HL7 in our monthly scan of ANSI-accredited standards under continuous maintenance. One of its parent standards, described below, is open for public review:

HL7 V2 Conformance. The intent of the project is to update the conformance methodology used to profile message definitions and to separate (divorce) the conformance chapter (currently Chapter 2B) from the ‘main’ HL7 v2 standard.

– Provide an independent (separate) HL7 v2 Conformance Methodology standard.

– Update the conformance constructs and profiling mechanisms used for implementation
guide creation

– Update the profile schema that supports the XML computable representation for implementation guides and message profiles

– Deprecate by means of an errata the Conformance chapter/section from all prior V2 versions. (our expectation is that the content of conformance testing of existing IGs will not change, but going forward any new specification will use this updated conformance methodology). To be clear, the proposal is an updated method of how to specify conformance for new IGs.

– Identify opportunities to encourage adoption by external implementation guide developers (e.g., IHE) to use the same conformance definitions and constructs.
