Safety laminated glass produced by “Magistral Ltd” is testing according GOST P 51136-2008 requirements and customer's drafts in geometry, composition, transparency, optical properties, light stability etc. Subject to protection level we conduct impact-, breakdown- and bullet resistant tests.
Grand attention is given to the inspection of output products. Technical inspection department is fit out with all necessary equipment and product inspection plants according GOST 51136-2008.
“Magistral Ltd” quality policy
The main long-range goal of our enterprise activity is satisfaction of the needs, requests and expectations of our customers. To succeed in this activity we permanently control glass manufacture that is the basis for long-term demand of the company and enables us to increase our reputation as a reliable partner.
The first-priority importance in the enterprise’s activity is its customers’ satisfaction. Manufactured and sold products volume, proceeds and profit of the company are the characteristics of our customers’ satisfaction and their needs anticipation only.
This policy is being realized by:
- Satisfaction and anticipation of the current and future customers’ requests.
- Manufacturing of the stable high-quality products, growth of our products competitiveness and outlets extending.

Company’s management expects from the every employee high activity to implement this policy into enterprise labor activity.
Impact-resistant glass (class A)
To execute impact-resistant test special equipment is needed. That equipment enables to influence the tested sample with the single attack of free-falling steel 4,11 kg ball from the heights of 3,5; 6,5 and 9,5 meters. Ball should attack every sample three times from the stated height into the equilateral triangle vertexes. After each blow type of destruction should be estimated.
Breakdown-resistant glass (class B)
Resistance of glass against breakdown may be controlled on equipment which enables to hit the tested sample with the hammer or axe. Hit velocities should provide the specified stress energy at the moment of the strike. Angle between surface normal of the sample and tangent to the axe blade should be equaled to 65±3.5?. The test starts with the hits of hammer pane or axe back in the sample until its destruction. After that axe blade hits crushed spots until the through square hole is made. Protection level may be defined according to the total amount of axe back and blade hits.
Breakdown-resistant glass classification:
Glass bullet resistance is controlled in the shooting galleries which provide the necessary protection level. Field test confirms that glass corresponds with the TND (technological normative documents) requirements in full. For the test 3 500*500 samples should be selected after climatic test. 3 shots should be made into the vertexes of the equilateral triangle (side length is 120 mm) on the each sample. Bullet velocity after each shot has to be measured and recorded. Type of destruction has to be controlled after every shot under the witness plate and back side of the sample. Punch is the through shot made by the bullet or by the spall in the sample surface.
