BUILDINGS AND STRUCTURES. Methods of Measuring The Illuminance

Introduction date -2013 - 01-01

1 area of \u200b\u200buse

This standard establishes methods for determining the minimum, medium and cylindrical illumination, the natural light coefficient (CEO) in the premises of buildings and structures and in the workplace, the minimum illumination of the work of the work outside buildings, the average lighting of streets, roads, areas, semi-cylindrical illumination of pedestrian zones.

2 Regulatory references

This standard uses regulatory references to the following standards:

5 Preparation for measurements

5.1 Before measuring the illumination and CEO for compliance with the requirements or GOST 12.1.046 and, choose and apply control points to measure the illumination and Keo on the plan of the room, structure or the illuminated area (or an actuator drawing of the lighting installation) indicating the placement of the lamps.

5.2 Before measuring the illumination from artificial lighting, it should be replaced by all burned lamps and cleaning the lamps. Light measurement can also be carried out without prior preparation of the lighting installation, which should be fixed when the measurement results are cleared.

5.3 Measuring the CEO for compliance with the current standards is carried out in rooms free from furniture and equipment that are not shaded with landscaping and trees, during washed and serviceable translucent fillings of lighting. At the same time, the weighted average reflection coefficient of wall, ceiling, gender and filling window openings in residential premises should be at least 0.5.

5.4 To measure the Keo, choose days with a continuous uniform decade bullic cloud that covers the entire sky. In areas located south of 48 ° C. Sh., Measurements of the CEO is allowed to be carried out without taking into account the ballotics in the days of continuous cloud, covering the entire sky. Artificial lighting in the premises for the measurement period is turned off.

5.6 Placing control points when measuring medium lighting of premises

5.6.1 To determine the control points, the room plan is divided into equal, if possible

square parts. Control points are placed in the center of each square. The minimum number of control points for measurement is determined based on the size of the room and the height of the luminaires of the lamps above the working surface. For this, the index index is calculated i. according to the formula

S. K - Square area, m 2.

5.6.3 When placing control points on the plan of the room, their grid should not coincide with the lamps of the lamps. In the case of coincidence of grids, the number of control points on the plan of the room is advisable to increase (see Figure A.3 Annex A). When locating in the room of large-sized equipment, control points should not be located on the equipment. If the control points fall on the equipment, then the mesh of the control points should be made more frequent and eliminate the points falling on the equipment.

5.7 Placing control points when measuring cylindrical lighting of rooms

5.7.1 Control points for measuring cylindrical illumination should be placed evenly on the room under the lamps, between the lamps and on the central longitudinal axis of the room at an altitude of 1.5 m above the floor and at a distance of at least 1.0 m from the wall.

5.7.2 The number of test points for measuring cylindrical illumination should be at least five.

5.8 Placement of control points when measuring the minimum illumination in places of production outside buildings

5.8.1 Control points are placed in the workplace, along the way of movement of working. On the illuminated area, limited supports, the control points are chosen in the centers between the supports.

With security lighting, the control points are located around the perimeter of the illuminated territory.

5.8.2 The number of checkpoints on the illuminated area or around the perimeter of the illuminated territory should be at least five.

5.9 Placement of control points when measuring medium light illumination, roads, squares

5.9.1 On the illuminated object determine the calculated field or control area. For objects with standard geometry, the control area is part of the rectilinear horizontal canvas of the road, the width of which is equal to the width of the entire carriageway W L.(when driving one way), and the length is a step S. Between the lighting devices located on one side of the road or in the center when setting the lighting devices along the axial line. When determining the illumination for the chess scheme of the location of the lighting devices, the length of the control portion S.

5.9.2 The number of checkpoints should be at least ten. Examples of the location of control points with different location of the lamps, as well as in the places of rounding and intersection, are shown in the Figures A.4 - A.7 of Annex A.

5.10 Placing control points when measuring the coefficient of natural illumination of rooms

5.10.2 The number of checkpoints should be at least five. The number of control points should include a point in which the illumination is normalized.

1 area of \u200b\u200buse

This standard establishes the methods for determining the minimum, middle and cylindrical illumination, the coefficient of natural light in the premises of buildings and structures and in workplaces, minimal illumination in places of production outside buildings, the average lighting of streets, roads, squares and tunnels to which SNIP 23 is distributed -05-95.

4. Equipment

4.1. To measure the illumination, the luxmeters with radiation transducers have a spectral error of no more than 10%, which is determined as an integral deviation of the relative curve of the spectral sensitivity of the radiation transducer from the curve of the relative spectral light efficiency of monochromatic radiation for the day vision V () according to GOST 8.332.

4.3. To measure voltage in the network, the accuracy class voltmeters should be applied not lower than 1.5 according to GOST 8711.

5. Preparation for measurements

5.2. The measurement of Keo is carried out in rooms free from furniture and equipment that are not shaded with landscaping and trees, when washed and serviceable translucent{!LANG-25d0de44ac85eb748d08cf06df2c49bd!} translucent{!LANG-b4899c7687b916b9f2058acb6de14980!}
