 How Windscreen Glass Breaks.
 
 
 Windscreens and safety glass are made from a "sandwich" of plastic laminate between two layers of glass. An impact strong enough to damage the hard outer layer can cause an infinite variety of chips, cracks, crescents, stars or combination breaks. Often the imperfection is tiny at the surface and expands into the familiar 'bulls-eye' shape as it spreads toward the centre layer. Glass Technics system of repair has specific resins, tools, and accessories to address every kind of damage.
 

 
 

 MOT Regulations : UK
 
 MOT Inspection Manual : June 2002.
Section 8.3 Windscreen
The inspection applies to: all vehicles (including those with opening windscreens)
 
Repaired Windscreens.
Repaired windscreens must be inspected to the same test criteria as original unrepaired windscreens. Repairs must be judged solely on the basis of whether they interfere with vision. *An invisible or barely detectable repair, finished flush with the surrounding glass does not count as damage even if it exceeds the limits on damage allowed in the test.* If these criteria are met, the position and size of repairs is not relevant for the purposes of the test.
Scratches.
Scratches on the windscreen ie light surface scratching, are not to be considered as damage. However, an area of concentrated scratching such as caused by the prolonged use of a defective wiper blade which obscures vision is to be considered a reason for rejection if it meets the fail criteria.
Method Of Inspection.
Referring to the diagram below, examine the windscreen wiper swept area of the windscreen and the driver’s view through it.
 
Windscreen Inspection Zones

Zone ‘A’ is:
* In the swept area of the windscreen.
* 290mm wide (cars) 350mm (hgv)
* centred on the centre line of the steering wheel
 
Reasons for Rejection / Failure.
1. In Zone ‘A’
a. the damage exceeds a 10mm diameter circle
b. a combination of minor damage areas which seriously restricts the driver’s view.
2. In the remainder of the swept area
a. the damage exceeds a 40mm diameter circle
Notes.
Repairs to damage of any kind, to windscreens, including Zone ‘A’, provided that the repair does not distort the view to the front or distract the attention of the driver, the repairs are permissable. Any blemish left in the repaired area does not exceed the fail criteria set out in section 8.3 of the MOT Inspection Manual.
 
 
 
 THE PRESERVATION, ENHANCEMENT & PREVENTIVE CLEANING OF GLASS
 
To obtain the benefits of “Easy Clean” windows, mirrors, shower doors, glass partitions and tables requires understanding the nature of glass and the impact of weather & water on its surface
 
The Nature of Glass
Glass is easily one of our most perfect materials. With its strength, insulation qualities and beauty, it is absolutely essential for light transmission and visibility. We can’t even imagine homes and buildings without windows, mirrors and a broad range of artifacts and furnishings made of glass. Yet, whatever its form or composition, the natural surface of glass is hydrophilic, non-conductive and microscopically irregular. It attracts and holds moisture and water-borne soil on its surface; it permits static electrical charges to remain on the surface and attract dust and dirt; and it allows its microscopic pores to trap a myriad of reactive chemicals, particulate matter and atmospheric contaminants that ultimately lead to weathering, soiling, staining and erosion...and reduced clarity.
 
The Impact of Weather & Water on the Surface of Glass
Rain, sleet, snow and spray from lakes and oceans, contains enough dissolved gases, carbonic acid, chlorides, sulfates, nitrates, ammonia and particulate matter to be chemically active. Similarly, most ground and municipally supplied water, while generally safe for drinking, cooking, washing and bathing, still contains enough salts, hard water minerals, bacteria, organic and inorganic contaminates and water treatment chemicals to also be chemically active.
When either source of water is allowed to evaporate on everyday glass viewing surfaces, it combines with ordinary soil to promote the formation, adhesion and buildup of insoluble mineral deposits, lime scale, rust and soil film. Thus, until it rains distilled water, windows will never be self-washing! Likewise, until ground and municipal water is completely de-mineralized, glass surfaces exposed to tap water – and water-containing spills and splatters – will be subject to the formation, adhesion and buildup of insoluble soil.
 
Measures to Maintain the Clarity of Glass
The mechanism by which water impacts glass surfaces, whether vertical or horizontal, is primarily through evaporation. As the H2O components evaporate, it allows the other inherent chemically active components of water to combine with everyday soil and attach to the surface. By making everyday glass surfaces more hydrophobic, i.e., more water & soil repellent, the formation, adhesion and buildup of insoluble soil is dramatically reduced.
