19、e cupboards for pharmacies with variable air volume, with the following alterations and additions. 7.1.2 The underbench unit functioning as the supporting construction of the fume cupboard shall allow a load of at least 1 000 N/m2. 7.1.3 The work surface shall be able to withstand a load of at least
20、 200 N over an area of 120 mm 120 mm without any damage or lasting deformation occurring. 7.1.4 The work surface shall have a raised edge with a height of at least 5 mm on all sides and shall also be impermeable. Bench coverings without joints, e.g. in accordance with DIN 12916, shall be used. The w
21、ork surface shall be easy to clean and, if need be, to disinfect. 7.1.5 Drainage components (e.g. drain funnel, basin or drainage channel) shall be installed so as to be impermeable to liquids.

When testing the containment robustness in accor
26、dance with DIN EN 14175-3:2004-03, 5.4 the determined tracer gas concentration (SF6) may be 0,65 106at most. See also Bibliography 1. 8.2 Testing The following tests shall be executed for the air flow type test: a) face velocity in accordance with DIN EN 14175-3:2004-03, 5.2; b) containment in the o
27、uter measurement plane in accordance with DIN EN 14175-3:2004-03, 5.3; c) robustness of containment in accordance with DIN EN 14175-3:2004-03, 5.4; d) pressure drop in accordance with DIN EN 14175-3:2004-03, 5.6. The number of test gas injectors shall be reduced from nine to six for fume cupboards w
28、ith widths 1 000 mm (compare Table 1) so that this results in a test gas flow rate of 3 l/min. The central vertical row of test gas injectors shall be omitted.

NOTE General requirements for visual danger signals are specified in DIN EN 842. See Bibliography 2. The fume cupboard air flow indicator need not be in operation if the fu
31、me cupboard is switched off. A secure operating mode of the fume cupboard shall be visible immediately after being switched on, e.g. by linking with the fume cupboard lighting. DIN 12924-4:2012-02 7 Special attention is to be paid to the corrosion resistance of sensors and, if need be, actuators wit
32、hin the extract air system. 9.2 Testing Testing of the fume cupboard air flow indicator shall be executed in accordance with DIN EN 14175-3:2004-03, Clause 7, and by a visual test of the additional requirements specified in 9.1. 10 Services 10.1 General Design shall be in accordance with DIN EN 1417
