An interesting concept arises with Level IV plates. Most buyers wrongly assume that a Level IV will pass the Level III test.
This anomaly is because Level IV must resist “ONE” shot of severe impact, whilst the Level III plate must resist “SIX” shots of less severe impact.
This fact apparently contradicts all previous advice on ascending ballistic levels. In practice the two tests can (and should) not be compared.
In the above the HAP-6 would pass a one impact pass at Level III on a M80 NATO Round. We know from experience the plate would fail at 6 shots. Many suppliers would be happy to verbally report their Level IV would sail through any Level III test. In reality this is not the case; which is why so few suppliers publish tables like the above.
Our HAP-7 plate offers the best all round solution to threats of unknown or changing threats. It covers all war-zone threats and deliberate high power rifle assassination threats. If a risk assessment concludes a “life threatening threat” from a military rifle, then we might suggest this plate to cover all eventuality. The HAP-7 has a capability that eliminates the need for professional advice when choosing a plate specification.
