Описание (английский):

Defines the conventional impact bodies used in order to reproduce the effect of actual impacts on vertical building elements as well as the general test procedures and the test procedures specific to each type of building element tested being given in the standards specific to these building elements. Applies to all vertical building elements excluding doorsets.

Abstract

Overview

Key topics and technical requirements

Scope and intent: Provides a harmonized method for creating repeatable impact conditions representative of actual impacts on facades, partitions, cross-walls and other vertical building elements.
Three classes of impact bodies:
- Hard bodies: steel ball-bearings (examples in the standard: 500 g with 50 mm diameter; 1 kg with 62.5 mm diameter) used to simulate impacts from stones or sharp furniture corners.
- Small soft bodies: a 3 kg rubber/ canvas ball (100 mm diameter) filled with a sand/lead-shot mixture to simulate localized deformable impacts (e.g., fists, small objects, footballs).
- Large soft bodies: a 50 kg spheroconical tarpaulin bag filled with 3 mm glass marbles to simulate large-area impacts (e.g., human body shoulder impacts or falls).
General test procedures:
- Impacts are produced by a pendular drop mechanism; the impact body is suspended and released to fall pendularly onto the specimen.
- Test apparatus must reproduce actual support and anchorage conditions so that energy absorption is not altered; allowable displacements of fixings are limited (example: < 0.1 mm under impact).
- Orientation rules: the tangent plane at the impact point should be at right angles to the pendular fall plane unless specific element standards indicate otherwise.
- Drop heights and impact angles are not set in ISO 7892 itself but are determined in the standards specific to each building element.

Practical applications and users

Who uses ISO 7892: test laboratories, façade and partition manufacturers, building envelope consultants, structural engineers, product certification bodies, and standards authors specifying impact resistance performance.
Why it matters: Provides repeatable, comparable methods for evaluating the ability of vertical building elements to resist accidental or exceptional impacts-important for safety, durability, compliance, and specification of materials in buildings.
