Foreword
This document (EN 1650:2008/FprA1:2012) has been prepared by Technical Committee CEN/TC 216
“Chemical disinfectants and antiseptics”, the secretariat of which is held by AFNOR.
This document is currently submitted to the Unique Acceptance Procedure.
1 Modification to 5.2.2.3, Malt extract agar (MEA)
Replace the whole sub-clause 5.2.2.3 with the following:

"Malt extract agar, consisting of:
Malt extract  30,0 g
Agar  15,0 g
Water (5.2.2.2) to 1 000,0 ml
The malt extract should be food grade (e.g. Cristomalt powder from Difal) or equivalent that is not highly
1)
purified and not only based on maltose (e.g. Malt extract from OXOID) . However if there are problems
producing at least 75 % spiny spores see 5.4.1.4.2.

Sterilize in the autoclave [5.3.2.1a)]. After sterilization, the pH of the medium shall be equivalent to 5,6 ± 0,2
when measured at (20 ± 1) °C.
NOTE In case of encountering problems with neutralization (5.5.1.2 and 5.5.1.3), it may be necessary to add
neutralizer to the MEA. Annex B gives guidance on the neutralizers that may be used."

2 Modification to 5.3.2, Usual microbiological laboratory equipment and in
particular, the following:
Replace the whole sub-clause 5.3.2 with the following:
“
5.3.2.1 Apparatus for sterilization
+ 3
a) for moist heat sterilization, an autoclave capable of being maintained at ( 121 )°C for a minimum
holding time of 15 min;
+5
b) for dry heat sterilization, a hot air oven capable of being maintained at (180 )°C for a minimum holding
+5 +5
time of 30 min, at (170 ) °C for a minimum holding time of 1 h or at (160 )°C for a minimum holding
0 0
time of 2 h.
5.3.2.2 Water baths, capable of being controlled at (20 ± 1) °C, at (45 ± 1) °C (to maintain melted MEA in
case of pour plate technique) and at additional test temperatures ± 1 °C (5.5.1).
5.3.2.3 Incubator, capable of being controlled at (30 ± 1) °C.
5.3.2.4 pH-meter, having an inaccuracy of calibration of no more than ± 0,1 pH units at (20 ± 1) °C.

This information is given for the convenience of users of this European Standard and does not constitute an
endorsement by CEN of the product named. Equivalent products may be used if they can be shown to lead to the same
results.
2)
Disposable sterile equipment is an acceptable alternative to reusable glassware.

A puncture electrode or a flat membrane electrode should be used for measuring the pH of the agar media
(5.2.2.3).
