General Specification

Earthing requirements for the installation of equipment having High Protective/Conductor currents. BS 7671:2008 Reg. 543.7

The scope of Reg. 543.7 requires that every final circuit intended to supply one or more items of equipment, where the total protective conductor current is likely to exceed 10mA in normal use, shall have a high protective connection.

GRP Systems

Load characteristics

Coefficient of safety > 1.7 (in accordance with IEC 61537) this data is given for ladders coupled with splice plates and bolts.

The deflection values are measured with the position of the junction between 2 ladders at a distance L/5 from a support. If this distance is not respected, it is necessary to raise the deflection values by about 30% when fully loaded.
 

PVC-U

Characteristics

Chemical Resistance

The material is virtually unaffected by solutions of inorganic acids, alkalis and salts and is resistant to many organic chemicals. It may be softened by some organic materials such as ketones and aromatic compounds. It will not corrode. See Chemical Resistance table opposite for further details.

Bio Antimicrobial Trunking

Silver Ion Technology

Silver ions are incorporated within the PVC-U material to deliver ongoing antimicrobial protection that prevents 99.9% of harmful bacterial growth. There is no reduction in the effectiveness of Bio Trunking throughout its life, even if it is scratched or damaged.

Test Results: Marshall-Tufflex Report #2422435
Laboratory: Thomson Research Associates Inc., Ontario, Canada
Test Organism: Methicillin Resistant Staphylococcus Aureus (MRSA)
 

The treated curved profile (Sample 2) showed excellent control of MRSA with a greater than 99.9% reduction in bacteria compared to the untreated flat profile (Sample 1). The bacteria grew on the untreated sample.
