This clause of Part 1 is applicable except as follows:

1.1 Scope

Replacement:This Part 2 is applicable to electrically powered laboratory centrifuges .

1.1.1 Aspects excluded from the scope

Addition:

- additional precautions which may need to be observed when centrifuging materials which are flammable or explosive (see 5.4.4.101);

- additional precautions which may need to be observed when centrifuging materials that chemically react vigorously (see 5.4.4.101).

1.1.1 Modification of 1.1.1 of the part 2 to add the following after the last dash:

- additional precautions related to safety hazards arising from leaking bioseals and other biosafety components.

1.1.2 Equipment excluded from scope

Addition:
