What is BS 6121-1 1989 PDF and Why You Need It

If you are looking for a reliable and comprehensive guide on mechanical cable glands, you might want to check out BS 6121-1 1989 PDF. This is a British Standard that specifies the performance requirements and dimensions for metallic cable glands for use with armoured cables. In this article, we will explain what BS 6121-1 1989 PDF is, what it covers, and how you can download and use it for free.

What is BS 6121-1 1989 PDF

BS 6121-1 1989 PDF is a document that contains the specifications for mechanical cable glands for use with armoured cables. Cable glands are devices that attach and secure the end of a cable to an equipment or enclosure. They provide strain relief, sealing, grounding, and protection for the cable and the equipment.

Armoured cables are cables that have a layer of metal armouring around the conductors to provide mechanical protection and electrical shielding. They are used in applications where the cable is exposed to mechanical stress, moisture, dust, or electromagnetic interference.

BS 6121-1 1989 PDF specifies the following aspects of metallic cable glands for armoured cables:

The types and sizes of cable glands

The materials and finishes of cable glands

The dimensions and tolerances of cable glands

The performance requirements and tests of cable glands

The marking and packaging of cable glands

What does BS 6121-1 1989 PDF cover

BS 6121-1 1989 PDF covers four types of metallic cable glands for armoured cables:

Type A: For use with single wire armour (SWA) cables

Type B: For use with braided armour (BA) cables

Type C: For use with steel tape armour (STA) cables

Type D: For use with lead sheathed cables

Each type of cable gland has different sizes ranging from 16 mm to 90 mm in diameter. The sizes are based on the nominal outside diameter of the inner sheath of the cable.

BS 6121-1 1989 PDF also specifies the materials and finishes of the cable glands. The materials include brass, aluminium, steel, stainless steel, and zinc alloy. The finishes include electroplated nickel, zinc, or cadmium; anodized aluminium; or painted steel.

BS 6121-1 1989 PDF also specifies the dimensions and tolerances of the cable glands. The dimensions include the length, diameter, thread size, hexagon size, sealing ring size, and clamping range of the cable glands. The tolerances include the permissible deviations from the nominal dimensions.

BS 6121-1 1989 PDF also specifies the performance requirements and tests of the cable glands. The performance requirements include the mechanical strength, electrical continuity, ingress protection, corrosion resistance, temperature resistance, and flame retardance of the cable glands. The tests include the tensile test, torque test, continuity test, water immersion test, salt spray test, heat ageing test, and flame test.

BS 6121-1 1989 PDF also specifies the marking and packaging of the cable glands. The marking includes the manufacturer's name or trademark, the type and size of the cable gland, and any relevant information or instructions. The packaging includes the quantity, weight, and dimensions of the cable glands.
