Flame resistance/fire resistance

Materials are described as “flame-resistant” if they prevent the spread of fire or are sufficiently fire-resistant. Ac- cording to DIN EN 60695-2-11 (VDE 0471 Part 2‒11), electrical connection materials must be subjected to a glow wire test, in order to evaluate the fire risk of the end product. When the glow wire test is being carried out, a glowing wire (for temperature see table below) is inserted into the component to be tested for a period of 30 seconds and then removed. After 30 seconds at the latest, the object, if it has caught light, must have extin- guished again, in order to specify the flame resistances.

In electrogalvanisation, the component is coated by dipping it not in molten zinc, but in a zinc electrolyte, through which a direct elec- tric current is passed.

Hot-dip galvanising

In hot-dip galvanisation, steel is coated by dipping it in molten zinc at a temperature of around 450 °C.

“Continuous galvanising” or “strip galvanising” is where a continuous ribbon of steel is galvanised in a continuous line.

“Batch galvanisation” is mainly used for galvanising prefabricated steel parts. 01_VBS / en / 2019/02/21 09:33:37 09:33:37 (LLExport_02514) / 2019/02/21 09:34:05 09:34:05

Protection class Resources with protective conduction connection (protection measure through protective conductor con- I nection on housing) II Resources with protective insulation (protection measure through insulation) Resource with protective low voltage III (SELV-PELV, protection through measured voltages max. 25/50 V AC and max. 60/120 V DC)

Empty plastic housings corre- spond to protection class II, housings made of metal/metal plating must be intended for the connection of a protection conductor and thus meet protection class I.

UL Underwriters Laboratories (UL) is an independent organisation that tests and certifies product safety. UL certification is generally required if a product is to be sold on the US market. UL offers various certification options: the “UL Listed” test mark indicates that UL has tested representative samples of a product and that it conforms to UL’s safety requirements. The “UL Recognized” component test mark entitles a product to be used in a product or system bearing the “UL Listed” test mark. 01_VBS / en / 2019/02/21 09:33:37 09:33:37 (LLExport_02514) / 2019/02/21 09:34:05 09:34:05

*The minus values apply only for parts in the quiescent condition with no severe impact stress. There is no plastic that is resistant to every chemical. The agents listed are only a small selection. Plastic parts are especially at risk in the presence of chemicals and high temperatures. Stress cracks may occur. If in doubt, please consult us and/or ask for a detailed chemical resistance table. Stress crack formation: stress cracks may occur if plastic parts under tension are exposed to chemicals at the same time. Parts made of polystyrene and polyethylene are particularly susceptible. Stress cracks may even be caused by agents to which the plastic in question is resistant in the absence of stress. Typical examples of parts under constant stress when used as intended: grip clips, intermediate supports of cable glands, ribbon clips. 01_VBS / en / 2019/02/21 09:33:37 09:33:37 (LLExport_02514) / 2019/02/21 09:34:05 09:34:05
