GOST 32566-2013 PDF

Full title and description

GOST 32566-2013 — "Glass and glass products. Test method of bullet resistance" (Russian: "ГОСТ 32566-2013. Стекло и изделия из него. Метод испытаний на пулестойкость"). The standard defines a laboratory method for determining bullet (ballistic) resistance of multi-layer bullet-resistant glass and glazed units that include bullet-resistant glass.

Abstract

This standard specifies procedures, test geometry, instrumentation and acceptance criteria for conducting ballistic (bullet resistance) tests on glass and glass assemblies. It covers sample mounting and fixation, target area dimensions, use of a control screen behind the specimen, measurement of projectile velocity, permitted measurement tolerances, and assignment of protection classes based on specified ammunition and impact conditions. The method is intended for type, qualification, certification and periodic testing of bullet-resistant glazing.

Scope

The standard applies to glass and products made from glass, in particular multi-layer bullet-resistant glass and various types of insulating glazed units (IGUs) incorporating multi-layer bullet-resistant glass. It establishes a reproducible test method for assessing resistance to small-arms and specified hunting cartridges under defined firing conditions; the method may be applied to other glass types when ballistic resistance needs to be determined. The procedure is intended for qualification, type approval, certification and periodic testing.

Key topics and requirements

• Test configuration: specimen clamping (all four edges uniformly clamped), target/aiming area dimensions (typical target area ≈ 440 x 440 mm) and minimum clearance requirements.
• Control screen: a thin control screen (cardboard or aluminum foil) is placed behind the specimen at a specified distance (typically 150 ± 10 mm) to detect perforation or through-penetration.
• Velocity measurement: velocity of projectiles is measured at a defined point (commonly about 3.0 ± 0.1 m from muzzle) with permitted measuring error not exceeding 1%.
• Ammunition and weaponation: the standard lists representative cartridges and weapon types for assigning protection classes (examples include hunting 12‑gauge loads and pistol cartridges such as 9×18, 9×19, 9×21 with specified projectile types and velocities).
• Classification and acceptance: results (perforation, back-face effects, vestigial damage) are used to assign protective classes (e.g., C1 and Br1–Br3 or similar classes depending on the table of threats included in the standard).
• Instrumentation and measurement tools: references to dimensional and measuring standards (e.g., GOST 427 rulers, GOST 166 calipers) and requirements for measurement accuracy.

Typical use and users

Testing and certification laboratories, manufacturers of bullet-resistant glass and protective glazing systems, inspection and conformity-assessment bodies, military and law-enforcement procurement departments, security consultants and designers of protected facilities use this standard to verify ballistic performance and to support product certification and selection of glazing for security applications.

Related standards

GOST 32566-2013 references and aligns with other standards for terms, measurement and related procedures — for example, ГОСТ 32539-2013 (glass — terms and definitions) and measurement/auxiliary standards such as GOST 166 (calipers), GOST 427 (rulers), GOST 7933 (cardboard control screen) and GOST 618 (aluminium foil). It is published as an interstate (Межгосударственный) standard and should be used in conjunction with related national/regional ballistic and glazing standards where applicable.
