PRO-LOCK SECURITY DEVICES1. Introduction:

1.1 Maritime Navigation Systems Group (MNS) DERA Fraser Portsmouth, part of the Defence Evaluation and Research Agency, is an independent shoreside test laboratory equipped to conduct Type Approval and Prototype Testing of Marine Navigational and Safety Equipment.

1.2 The Test Laboratories at DERA Fraser have been Accredited by the United Kingdom Accreditation Service (UKAS) for Performance and Environmental testing on a wide range of Marine Navigational and Safety Equipment.

2. Customers Requirement:

Pro-Lock UK supplied DERA Fraser with a quantity of the Polypropylene version of their security devices. Both Standard and Standard Plus versions of the device were supplied for testing. The customer required the devices to be tested to selected temperature extremes with the addition of a drop/shock test to be conducted on the devices at the temperature extremes.

3. Environment:

 PRO-LOCK VALVE LOCKOUT - Environmental Testing  - Photographs 3.1 The devices were environmentally tested to the following temperatures:

3.1.1     +55C / +131F

3.1.2     -55C / -67F

4. Test Procedure:

-55C / -67F Test

4.1 Four devices plus spanners and tools were placed in an Astell Chamber and the chamber reduced in temperature to -55C / -67F. This temperature was maintained for 24hrs after which the devices were removed and a functional test conducted. This entailed locking and unlocking both versions of the device using the tools from the sub zero environment.

Drop Test

4.2 The devices were then subjected to a drop test. They were dropped from a height of 1.5metres onto a steel plate. This was repeated three times on each of the four devices, spanner and tools. After each drop a functional test was conducted.

Shock Test

4.3 The devices were then subjected to a shock test. They were swung overhand and struck against a steel plate. This was repeated six times on each device. After each shock a functional test was conducted.

+55C / +131F Test

 PRO-LOCK VALVE LOCKOUT - Environmental Testing  - Photographs 4.4 The locking devices were returned to ambient temperature, as was the Astell Chamber and the chamber increased in temperature to +55C / +131F. This temperature was maintained for 24hrs after which the devices were removed and a functional test conducted. This again entailed locking and unlocking both versions of the device.

Drop Test

4.5 The devices were then subjected to a drop test. They were dropped from a height of 1.5metres onto a steel plate. This was repeated three times on each of the four devices, spanner and tools. After each drop a functional test was conducted.

Shock Test

4.6 The devices were again subjected to a shock test. They were swung overhand and struck against a steel plate. This was again repeated six times on each device. After each shock a functional test was conducted.

5. Conclusions:

5.1 The items of Pro-Lock equipment that have undergone the tests detailed in this document continued to function satisfactorily and sustained no visible damage that impaired their performance.
