BS EN 13060
BS EN 867:5
MDA DB 9804

For steriliser chambers with a volume of more than 54 Litres and diameter of 35cm or greater.

For steriliser chambers with a volume of between 10 litres and 54 Litres and diameter of between 18cm and 35cm.

The test pack should be made up of cotton sheets (warp threads/cm = 30 ±6 and weft threads/cm = 27 ±5), 900mm x 1200mm, unhemmed and bleached to white.

The test pack should be made up of cotton sheets (warp threads/cm = 30 ±6 and weft threads/cm = 27 ±5), 450mm x 300mm, unhemmed and bleached to white.

The sheets should be washed without fabric conditioner when new or require washing.

The sheets should be dried and equilibrated for 1 hour prior to use at a temperature of between 15°C to 25°C, humidity being between 30% and 70%.

The sheets should be dried and equilibrated for 1 hour prior to use at a temperature of between 20°C to 30°C, humidity being between 30% and 70%.

The sheets should be dried and equilibrated for 1 hour prior to use at a temperature of between 15°C to 25°C, humidity being between 45% and 55%.

Each sheet should be folded to approximately 300mm x 220mm.

Each sheet should be folded to approximately 110mm x 150mm.

Stack folded sheets to a height of 150mm and weight of 4kg +/-0.5kg. The pack should be compressed by hand during stacking.

Stack folded sheets to a height of 120mm and weight of 900g +/-30g. The pack should be compressed by hand during stacking.

Stack folded sheets to a height of 120mm and weight of 900g +/-100gThe pack should be compressed by hand during stacking.

When stacking, the fold of the sheet should be alternated to form an even pack. 

Use either a prepared cotton sheet or a test pack wrap to secure the sheets.

Use one of the prepared sheets to wrap the test pack, securing with autoclave tape not more than 19mm wide.

The constructed standard test pack can be re-used. Store in an environment as described above for washing.

The sterilisation process will result in the test pack compressing, simply add further sheets to make the pack height 120mm, checking that the weight remains with tolerance. When the pack weight breaches 4.5kg dispose and replace with new sheets.
