Combating Galvanic Corrosion at CMP
The type and thickness of nickel coatings applied to brass cable glands varies significantly around the world, and many of the solutions adopted are inherently porous, meaning that they are unable to provide complete protection against chemical attack, corrosion, or material break-down. There are typically two types of nickel plating in common use, these being electro nickel plating and electro-less nickel plating.

Local codes of practice or regulations may be in force to ensure that safety is maintained to eliminate the possibility of accidents arising from the danger of electricity. These dangers would include electric shock, burns, fire, explosion and arcing. In the United Kingdom the ESQCR 2002, and amendments 2006 (S.I. No. 1521) and 2009 (S.I. No. 639), introduced under Statutory Instrument No. 2665, and the Electricity at Work Regulations 1989 (EAW Regulations), which came into force on 1 April 1990, comprehensively deal with this subject.

In accordance with API 500 (14F), API 505 (14FZ), National Electrical Code (NEC) 2020 and C22.1-18 (Canadian Electric Code) any cable for use in a classified location must firstly be of a type permitted in the location, and secondly be tested and approved to standards specific to the application.
