9 Diffusers
9.1 A panel or lens shall be investigated with regard to mechanical strength. The Investigation will include consideration of the ability 01 the panel or lens to withstand the forces, including impact, to which it may be subjected after installation. A lurninaire shall be tested as described in the Impact Test, Section 36. For a polymeric material, consideration will be given to thermal conditioning.
10 Guards
10.1 A metal guard, when provided, shall be conductively connected to tile point of attachment of the equipment grounding conductor to the luminaire.
10.2 If a luminaire must be provided with a guard in order to comply with the requirements concerning the risk of electric shock, the construction shall be such that the luminaire cannot be installed without the guard.
10.3 There shall be no sharp or protruding edges of a guard or other parts of the luminaire that may be contacted by persons in a pool.
11 Gaskets
11.1 A gasket shall be of a material able to withstand the temperature and use to which it will be subjected. The gasket material shall be resistant to aging. A gasket that will be disturbed during routine servicing, such as during lamp replacement, shall be formed of resilient material such as neoprene or silicone rubber.
11.2 A gasket of neoprene, rubber, neoprene composition, or rubber composition used to prevent the entry ol water into a luminaire shall be subjected to the Gasket Accelerated Aging Test, Section 38.
11.3 A gasket material other than those specified in 11.2 is not prohibited from being used when determined to have equivalent characteristics, including resistance to aging. Such material is considered resistant to aging when there Is no visible evidence of deterioration (such as cracking after flexing, softening, or hardening) after these characteristics are investigated.
