Target test Sample Clauses
A Target Test clause sets a specific standard or benchmark that must be met, often as a condition for performance or acceptance in a contract. In practice, this clause might require that a product, service, or process achieves certain measurable results—such as a minimum efficiency rate, compliance with technical specifications, or passing a quality inspection—before obligations are considered fulfilled. Its core function is to provide an objective basis for evaluating whether contractual requirements have been satisfied, thereby reducing ambiguity and potential disputes over performance.
Target test. 9.3.1.1.1. Apparatus This method involves viewing an illuminated target through the safety glazing. The target may be designed in such a way that the test can be carried out on a simple 'go-no go' basis. The target shall preferably be of one of the following types; that is to say, either
(a) An illuminated 'ring' target whose outer diameter, D, subtends an angle of n minutes of arc at a point situated at x metres (Figure 11(a)), or
(b) An illuminated 'ring and spot' target whose dimensions are such that the distance D from a point on the edge of the spot to the nearest point on the inside of the circle subtends an angle of n minutes of arc at a point situated at x metres (Figure 11(b)), where n is the limit value of secondary-image separation, x is the distance from the safety glazing to the target (not less than 7 m), D is given by the formula: D = x . tg n The illuminated target consists of a light box, approximately 300 mm x 300 mm x 150 mm, whose front is most conveniently constructed of glass masked with opaque black paper or coated with ▇▇▇▇ ▇▇▇▇▇ paint. The box shall be illuminated by a suitable light source. It may be convenient to use other forms of target, such as that shown in Figure 14. It is also acceptable to replace the target system by a projection system and to view the resulting images on a screen.
9.3.1.1.2. Procedure Mount the windscreen at the specified rake angle on a suitable stand in such a way that the observation is carried out in the horizontal plane passing through the centre of the target. The light box shall be viewed in a dark or semi-dark room, through each part of the area being examined, in order to detect the presence of any secondary image associated with the illuminated target. Rotate the windscreen as necessary to ensure that the correct direction of view is maintained. A monocular may be used for viewing.
