What is BS EN ISO 3506-1:2020 about?

This is the first in a six-part series of international standards on the mechanical and physical properties of stainless steel fasteners. BS EN ISO 3506-1:2020 covers specific types of bolt, screw and stud.

Who is BS EN ISO 3506-1:2020 for?

  • Manufacturers and distributors of stainless steel fasteners
  • Structural and consulting engineers
  • Construction and civil engineering contractors and larger sub-contractors
  • Test houses and laboratories
  • Industries associated with oil and gas production and distribution

Why should you use BS EN ISO 3506-1:2020?

It specifies the mechanical and physical properties of bolts, screws and studs, with coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless steels, when tested at the ambient temperature range of 10 °C to 35 °C.

It specifies property classes in relation to austenitic, martensitic, ferritic and duplex (austenitic-ferritic) steel grades for fasteners.

It applies to bolts, screws and studs with:

—      ISO metric thread in accordance with ISO 68-1

—      Diameter/pitch combinations in accordance with ISO 261 and ISO 262

—      Coarse pitch thread M1,6 to M39, and fine pitch thread M8×1 to M39×3

—      Thread tolerances in accordance with ISO 965-1 and ISO 965-2

—      Specified property classes and of any shape

 Together with BS EN ISO 3506-2:2020 and BS ISO 3506-6:2020 it

provides additional advice and guidance for most applications where these products will be required. 

There are other standards which deal specifically with specialized areas such as oil and gas but this considerably revised document provides an excellent foundation for any assessment.

NOTE: This standard does not specify requirements for functional properties such as: torque/clamp force properties, shear strength, fatigue resistance, or weldability.


BS EN ISO 3506-1:2020 can help users achieve UN Sustainable Development Goal 9 on industry, innovation and infrastructure because it contributes to the building of resilient infrastructure.

 

What’s new about BS EN ISO 3506-1:2020?

The standard has been revised to reflect the standardization of duplex stainless steels. The main changes in BS EN ISO 3506-1:2020 are:

a)       Annexes common to several parts of the ISO 3506 series have been withdrawn from this document and are now included in a new document (ISO 3506-6)

b)      Duplex (austenitic-ferritic) stainless steels for property classes 70, 80 and 100 have been added

c)       Property class 100 for austenitic stainless steel grades as well as grade A8 have been added

d)      Finish has been added

e)      The matching of stainless steel bolt and nut grades has been added

f)        Calculated minimum ultimate tensile loads and minimum loads at 0,2 % non-proportional elongation and rounding rules have been added

g)       Reduced loadability for fasteners due to head or shank design has been added

h)      Requirements and guidance for inspection procedures have been added

i)        Operational temperature ranges have been clarified

j)        The applicability of test methods, also in relation to full or reduced loadability, has been added

k)       The tensile test procedure has been entirely amended, and application to fasteners with reduced loadability has been added

l)        The wedge tensile test and hardness test have been improved

m)    Marking and labelling  have been improved, and fasteners with reduced loadability have been included

n)      Mechanical properties at elevated temperatures and application at low temperatures have been improved

The structure and content of this document have been brought in line with ISO 898-1
