EN285 - Standard Towel Packs

30/1/2019

The Standard Test pack is used to test the performance of an autoclave and ensure rapid and even penetration of steam within the pack. The test originates from UK Health Technical Memorandums (HTMs)and is well known from HTM2010.

Standard Test Packs are a great way of testing and setting up autoclave cycles. There use is detailed in EN285:2015 for the following tests:

·       Small/Full Load Thermometric Tests
·       Air Detector Performance Tests
·       Load Dryness Test
·       Air Detector Function Test

We often hear of failures during benchmark testing to EN285 and these can often stem from the preparation for the standard test pack. Below are a few simple ways to ensure your pack is suitable for use:

1. The pack should be laundered when soiled, this must be done without the use of detergent or conditioner (which may cause Non Condensable Gases)
2. The pack must be allowed to equilibrate between 20-30°C and a humidity of 40 to 60% RH.
3. The pack should weigh 7.0kg +/-0.14kg
4. The Pack should be folded as shown in Figure 13 of EN 285:2015.

The specification or the test pack is detailed in EN285:2015 section 23.1. If you would like to purchase suitable Standard Test Packs or if you have experienced failures and would like advice, please let us know and we would be happy to help.

We can also help with hire of

CO2 Incubator Mapping

30/1/2019

At Thermal Compliance we use several systems for temperature mapping and validation. We do this to ensure the system we use is best suited to your application.

For CO2 Incubators we use Ellab Tracksense CO2 sensors to map CO2. This sensor provides 21 CFR Part 11 compliant data and allows us to map CO2 for the duration of the validation. This allows our engineers to ensure your CO2 Incubator is optimised for your process.

Alongside our CO2 sensors we also use Ellab Tracksense Pro and Tracksense Lab sensors to map Temperature and Humidity. With a clear and concise Pass/Fail report detailing acceptance criteria for temperature, humidity and CO2.

If you would like to know more about how we can help and about our different CO2 Systems, please visit http://www.thermalcompliance.co.uk/humidity--co2-testing.html
