Compliance to British Standards

Ensuring reliability and compatibility.

Standards are used to establish consistent protocols that can be universally understood ensuring the reliability of the materials, products and services people use every day. Adherence to standards can make it easier to understand and compare competing products, but with such a broad range of standards out there covering fields as diverse as health and safety, the fire performance of materials, and safe access to machinery and equipment, it can be hard to ascertain which standards may affect the material selection for your particular project.

The following highlights the suitability of d² Dura Grating for some of the main standards in common usage for GRP flooring:

BS 4592 “Flooring, Treads & Handrails for Industrial use”

States that any opening should prevent the passage of a 35mm diameter sphere except where the grating is above a place where people are working as opposed to occasionally passing, then the openings should prevent a 20mm diameter sphere from passing through.

BS EN ISO 14122 “Safety of machinery” – “Permanent means of access to machinery”

States that openings should prevent a 35mm sphere from occasional passage underneath and a 20mm diameter sphere for spaces that are more regularly worked.

BS EN 13501-1 “Fire classification of construction products and building elements”

Assesses a material’s contribution to fire, smoke emissions and burning droplets. d² Dura Grating GRP flooring achieves a classification of B s1 d0 – meaning very limited contribution to fire, with the lowest possible smoke emissions and zero burning droplets. This test supersedes BS476 as it tests for smoke and droplets.
Norsok Working Environment Standard

d² Dura Grating also meets the specific requirements of the Norsok Working Environment Standard developed for the Norwegian Offshore Sector. This standard requires that grating used for Floors, Deck, Surfaces and Platforms shall not allow a ball of more than 20mm diameter to fall through. The 20mm grating open hole limit applies wherever there are persons working beneath the grating. If there is no-one working below the maximum opening can be 35mm in diameter.

Engineering confidence starts with the right standards.

When you specify a GRP flooring system, performance is only part of the equation. How do you know it meets the standards your project demands – from structural performance and fire safety to access and workplace requirements?

Standards provide the evidence and consistency needed to make confident specification decisions. But with multiple standards potentially applying to a single project, understanding exactly what matters can be complex.

Here, we examine the key standards relevant to GRP flooring and how d² Dura Grating has been engineered and tested to support safe, compliant and defensible specification.

The following highlights the suitability of d² Dura Grating for some of the main standards in common usage for GRP flooring:

BS EN 1990 “Basis of Structural Design”

Defines the structural safety, serviceability and reliability principles for all Eurocode structural calculations.
BS EN 1991 “Actions and Loading on Structures”

Establishes design loads and restrictions acting on structures for real-world operating conditions, including imposed loads, wind loads, snow loads and other environmental effects.

BS EN 13706 “Pultruded GRP Profiles”

Specifies the requirements for structural pultruded GRP profiles, including material classifications, dimensional tolerances, mechanical properties and quality control measures.
BS 4592 “Flooring, Treads & Handrails for Industrial use”

Provides design and performance requirements for moulded GRP open bar grating. States that any opening should prevent the passage of a 35mm diameter sphere except where the grating is above a place where people are working as opposed to occasionally passing, then the openings should prevent a 20mm diameter sphere from passing through.
BS EN ISO 14122 “Safety of machinery” – “Permanent means of access to machinery”

Establishes requirements for platforms, walkways, stairways, guardrails and fixed machine access ladders. States that openings should prevent a 35mm sphere from occasional passage underneath and a 20mm diameter sphere for spaces that are more regularly worked.
BS EN 13501-1 “Fire classification of construction products and building elements”

Assesses a material’s contribution to fire, smoke emissions and burning droplets. d² Dura Grating GRP flooring achieves a classification of B s1 d0 – meaning very limited contribution to fire, with the lowest possible smoke emissions and zero burning droplets. This test supersedes BS476 as it tests for smoke and droplets.

Network Rail & RIS Standards

Provides project-specific requirements for railway infrastructure, covering structural design, safety, durability, access and performance within the rail environment.
CDM Regulations 2015 & DMRB

Provides framework for safe design, construction and operation of highway infrastructure to satisfy National Highways requirements for structural performance, safety and durability.

European Standards

Many European countries, including Norway, Denmark, the Netherlands, Hungary, Sweden and Ireland, adopt national versions of EN and ISO standards. Many infrastructure, marine, offshore and energy projects specify internationally recognised DNV and NORSOK standards to demonstrate structural integrity, safety, durability and operational performance in demanding environments.
Australian Standards and Codes

Across Australia, compliance is commonly achieved through the National Construction Code (NCC) and Australian Standards, including AS/NZS 1170 for structural design actions, AS 1657 for access systems, AS 3996 for access covers and grates, AS 1530 for fire performance and a range of industry-specific standards covering rail, offshore, water and workplace safety applications.

Other International Standards

Across international markets, including the Middle East, projects commonly adopt Eurocodes, EN and ISO standards alongside local authority requirements, with standards such as EN 1090, EN 13706, ISO 14122, EN 13501, DNV and IEC.
