What Certifications should Spiral Guards be approved when applied to Underground Metal and Nonmetal Mines Circumstance?

British Coal Specification 182:1986 satisfies the requirements of the non-metallics scheme for use underground.

EN ISO 80079-36:2016 is the ATEX -related standard for Non-Electrical Equipment for Explosive Atmospheres.

ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres:

Directive 99/92/EC (also known as 'ATEX 137' or the 'ATEX Workplace Directive') on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.

Directive 2014/34/EU (also known as 'ATEX 114' or 'the ATEX Equipment Directive') on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

FRAS[Fire Retardant Anti Static] is a requirement for composite ventilation ducts used in underground mines, especially coal mines. The material must be conductive (anti-static as well as prevent propagation of a flame-fire retardant). The NSW Mine Safety Technology Centre[1] can conduct tests if the material complies with the requirements for use in New South Wales, Australia.

KA

It is China unique safety mark certification system that must be obtained for equipment and products used in non-coal mine sites.

MA

It is China unique safety mark certification system that must be obtained for equipment and products used in coal mines.

MDG41 [Mechanical Design Guideline #41 for fluid power safety at mines]

The guidelines were prepared in cooperation with New South Wales Department of Primary Industries (Mine Safety) safety and a number of Manufacturing Hose and Fittings companies.

MSHA [Mine Safety and Health Administration]

MSHA's Approval and Certification Center (A&CC) approves and certifies certain mining products for use in underground coal and gassy underground metal and nonmetal mines.
