Standards

All protective products made or supplied by VestGuard UK are manufactured in accordance to the international standards detailed below. We use independent accredited test facilities to regularly test our products to ensure they continue to meet the very latest standards required by our customers, with many products under test conditions often outperforming the standards. Our products are designed to protect our customers and have been developed and verified through in-house, independent and customer testing for over 15 years.

National Institute of Justice (NIJ) 0101.06

This is considered the most widely used internationally recognised standard. The standard covers protection against small handguns and anything up to armour piercing rifles. The standard is used for body armour, helmets and other armour solutions on the market, such as vehicle armour and shields.

This standard is split into levels of protection designated by roman numerals.

NIJ level II (2) Small handgun protection
NIJ level IIIA (3a)  High velocity handguns
NIJ level III (3)      Rifles
NIJ level IV (4)     Armour piercing rifles

UK Home Office (CAST) Body Armour Standard (2017)

The UK standards are set by the Home Office for the protection of police and government bodies. Adopted by many security and private companies in the UK, the protection covers a full range of threats including ballistic (HO), edged weapons like knives (KR), and spikes like needles (SP). The higher the threat the higher the number, i.e. HO1, HO2.

NATO STANAG 2920 FRAGMENTATION

This is the military standard for ballistic protection & armour solutions for military applications.

STANAG 2920: The adoption of standards for ballistic protection levels and testing relates typically to the levels of fragmentation protection that vests offer. The technical details are complicated but the results are identified as a V50 rating in metres or feet per second. VestGuard armour and helmets all have a V50 rating.
