The information below shows the paragraphs from HTM 01-05 2013 Edition Section 17.0 that have changed from those within HTM 01-05 2009 Edition.


Paragraph 17.8

Cleaning and rinsing (either manual or automated) can be performed with potable water as long as the water hardness is low enough and other aspects of water quality are satisfactory. This should be confirmed with the manufacturer of the washer-disinfector and detergent.

What the changes mean and how do they affect your practice?

The 2013 Edition removes the recommendations for endotoxin and water hardness levels, and specifies that advice of the washer disinfector manufacturer should be sought.


Paragraph 17.9

Practices should check with the detergent manufacturer that level of hardness is compatible with the detergent used and for its use in a washer-disinfector.

What the changes mean and how do they affect your practice?

The 2013 Edition specifies that manufacturer's advice should be sought with regards to water hardness. The 2009 Edition recommended that water softening was ‘expressly advised’.


Paragraph 17.11

The detergent should be chosen for its cleaning efficacy and its compatibility with the water quality.

What the changes mean and how do they affect your practice?

The 2009 Edition previously read ‘...compatibility with the potable water quality and parameters of its use’.
