The new AS1807 series was developed from a requirement to consolidate Twenty-Six individual standards in to one comprehensible test method that could be applied to a range of products. As a result there have been some notable improvements in transparency, test methodology and a reduction in the barriers of entry.

In this context the AS 1807 series of test methods is utilised by registered service organisations, Australian laboratories and associated safety cabinet users. Those groups have regularly completed an annual certification process under the guidance of National Australian Testing Accreditation “NATA”. This is due to the practical ease and transparency for delivering a rapid “pass or fail result” to end users at their work place environment which has resulted in high user uptake of more than 85% within the work place, significantly higher than any other regions of the world.

Consolidation of the various test methods would seem like an obvious solution however in the past this has not been the case. The driving force behind change came from an unlikely source; the adaptation of an ASNZ/ISO Clean Room Test Method that would likely cause conflict in the market.

So, what’s new?

AS1807, was given a new title “Separative Devices” with a clear definition for use “Biological and Cytotoxic Drug Safety Cabinets, Clean Workstations, and Pharmaceutical Isolators – Methods of Test”.  With a defined focus it is now clear where these standards should be applied. Test methods that are not applicable to the definition have been removed and about half have been revised and updated.

A critical aspect of the new standard was the requirement to independently validate the competency of service providers in the delivery of on-site technical services, safety cabinets and other separative devices to ensure that those devices are safe and fit for purpose at the users place of work.  The test validation process needed to be relevant, simple to apply, cost effective, provide a ready pass/fail outcome and reproduceable within any work place environment. A high level of importance was provided to the types of equipment to be used, and the effect of aerosol test challenge and pressures.

Driving this development was the increase in the range of deemed diseases, from what had been traditionally asbestos related diseases to include numerous additional types now included many found within the laboratory work place. AS1807:2021 appendix B table B1 references the higher risk posed to laboratory personnel for brucellosis, Q fever and Typhoid due to their low infectious doses and increased infection caused through aerosol inhalation.

In addition to the actual test methods, technical aspects of test equipment have been reviewed and updated. This includes anemometers, lighting, and the effect building vibration can place on the placement of bio safety cabinets in high rise buildings.

It is considered critical for effective measurement of HEPA sealing integrity to ensure an upstream concentration of aerosol. An effective range was considered to be 1mg /m3 to 100mg/m3.  Given the complexity within the test methods and how one test adjustment can impact another.

The new standard provides useful information for users and the industry by providing a guide of estimated times, one should consider when conducting tests in accordance to AS1807:2021. This guide is shown in Table 2.1 and offers users an indicative time frame for when their annual services are required. Procedure refers to the travers rate for effectively scan testing HEPA filters and references to the time using varying size tips and speeds between 0.3 to 0.6m/s are shown in Appendix D. Speeds outside the recommended test velocity are shown with a traverse rate of “0” and highlighted in blue.


The new AS1807 Standard combines all of the relevant individual standards in one convenient location. This has significantly reduced the cost of owning this standard and provides clarity to all user groups. Furthermore, the test methods have been refined and modernised based on research and to suit the latest equipment. This is more than comprehensive update of AS 1807; this new Standard sets out a clear test methodology with performance targets for Biosafety Cabinets and other Separative Devices that no other global standard clearly defines.

AS 1807:2021 is a focussed, locally developed standard that takes in to account the unique challenges that face stakeholders within Australia. This is unlike modern adaptations of global standards that take a broader approach to accommodate a wider user-group

AES Environmental produces Class II Biological Safety Cabinets that are instrumental in providing our researchers with a safe and clean environment. A Class II BSC protects the operator with an air barrier that has to meet a stringent performance test prior to use and during regular service and maintenance. The discharge of the Class II BSC is controlled by a H14 HEPA Filter, that is 99.995% efficient and ours are constructed in Australia to meet the stringent requirements of AS 4260.

The above clip from a Sky News report demonstrates how our products are used on the front line of research, not just for Covid-19 but for all situations where stringent control of aerosolised contamination is required.

On 6 December 2017 the Federal Court of Australia ordered that SPX Vokes UK Ltd pay Laminar costs and amend the registry in favour of Laminar in respect to ownership of the Vokes Trademarks in Australia.

SPX Vokes UK Ltd is an overseas affiliate of SPX Corp USA a NYSE publicly listed company head quartered in Charlotte North Caroliner USA, with a reported turnover of $2.4B . SPX Vokes applied using  section 81 of the trademarks act to claim ownership of Laminars property in Australia to which the Australian Trade Marks Office acquiesced. Laminar appealed this decision in the Federal Court and the matter was heard by Justice Robertson, who justly overturned the decision and awarded the Australian trademarks and costs to laminar Air Flow Pty Ltd the registered owner of the trademarks.

Vokes is a well-established brand in Australia, having first established in 1937 and then registering the “Vokes” name as a trade mark brand in December 1959. The Vokes trade mark name was approved on the basis of the significant trade established by the Australian entity. Vokes established its first air filtration manufacturing plant in Australia at Rockdale Sydney in 1962 and has continuously supplied the Australian, New Zealand and Asian export markets with quality filtration products.

Since 1993 Vokes has held ISO/QMS certificate number FS6054110 for design and manufacture of air filtration equipment, including biological safety cabinets, cytotoxic cabinets, electrostatic filters, HEPA filters and related special products.

Laminar acquired the “Vokes” brand from BTR Environmental in 2000.

Today Vokes continues to manufacture and market its brand of products in Australia, through licensed use and manufacturing IP to the AES Environmental group. AES is a specialist Australian owned filtration manufacturer, engineering, service and sales organisation that also markets the Email, Clyde-Apac, Lemcol, Selson and IFC Brands in Australia and in many overseas markets.

Cytotoxic Standard Changes, Publication of AS2252.5.

Standards Australia has published a new document, AS 2252.5, which concerns the construction and performance validation for Cytotoxic Drug Safety Cabinet’s (CDSC’s). The aim of this letter is to provide you with a brief on some of those changes and how they may impact on your laboratory in the future.

AS2252.5 incorporates several key aspects of room design where previously this was contained in other standards. Notably, there is a requirement for a capture exhaust within the cytotoxic suite and certification requirements surrounding room pressures, air change rates and temperatures, to name a few. The standard draws these requirements from a number of source documents including ISO 14644 parts 1 & 3, AS 1668.2, HEPA standards and 1807 test method standards.

CDSC’s have carbon filters fitted in order to reduce the risk to the environment and personnel of potential gaseous contamination that could be generated within the work zone of a CDSC. It has been determined that the carbon filter, due to the nature of its use, is required to be replaced annually, at point of service. This is a significant cost to the regular annual certification process of any CDSC. The replacement of the carbon filter has been determined as necessary due to an inability to validate, on-site, the remaining adsorption capacity of the carbon within the media.

An ISO Class 5 cleanliness rating is required within the work zone of the CDSC. This test requires a technician to undertake particle counting within the work zone of the CDSC while the unit is ‘at rest’, the validating technician will be responsible for the reporting of the results. This is an additional process, beyond the current annual certification requirements, and will likely see an increase in service cost due to use of specialist equipment and labour.

Minor changes include a relaxation of sound level tests and lighting intensity tests. With the sound level range moving higher, to allow for a greater operating sound level and the lighting intensity reducing, to allow for lower lighting levels. This is in line with the requirements of AS2252.2, Class II Biological Safety Cabinet’s (BSC’s) and the tests are now considered optional.

In addition to the above, there are also a number of changes related to cabinet design. Those have been omitted from this document as it will have little impact on the annual certification of the equipment that you currently have in your laboratory.

For more information related to the above or if you would like to discuss further how these changes may impact on your facility, then please feel free to contact the AES team at your convenience.
