GOST 2678-94 PDF

Full title and description

GOST 2678-94 — "Rolled roofing and waterproof materials. Methods of testing" (Материалы рулонные кровельные и гидроизоляционные. Методы испытаний). The standard specifies laboratory and field test methods used to determine the physical, mechanical and waterproofing properties of rolled roofing and membrane waterproofing materials.

Abstract

This interstate (GOST) standard provides standardized test procedures for sample preparation and determination of performance characteristics — including tensile and elongation, water absorption, water resistance under pressure, low-temperature flexibility, impact resistance and related acceptance checks — for rolled roofing and waterproofing materials used in building and construction. The procedures are intended to ensure repeatable, comparable results for quality control and regulatory conformity.

General information

• Status: Acting / active (GOST in force as an interstate standard and adopted in national catalogues).
• Publication date: 1996 (commonly cited as 01 January 1996; some national enactment records show adoption/enactment later in 1996).
• Publisher: Interstate (GOST) system — Interstate Council for Standardization, Metrology and Certification (EASC) / implemented nationally by Rosstandart and national standards bodies.
• ICS / categories: Construction materials and building — classification commonly listed in catalogue entries (classification example: 91.100.60 for construction/thermal & sound insulating materials).
• Edition / version: Original GOST 2678-94 edition (1994 adoption / 1996 publication/enactment) with later amendments referenced in catalogues (amendments published in 1998 and textual changes noted in national indexes).
• Number of pages: Approximately 31 pages (electronic/printed editions commonly listed as 31 pp.).

Scope

GOST 2678-94 covers test methods applicable to rolled roofing and waterproofing materials (bituminous felts, polymer-modified membranes, reinforced sheets and similar roll-applied products). It prescribes sampling, conditioning and test procedures to evaluate mechanical properties, waterproofing performance and durability indicators used for quality control, specification compliance and comparative product assessment. The standard is used both in laboratories and in field checks where specified.

Key topics and requirements

• Scope and definitions for rolled roofing and waterproofing materials and relevant test specimens.
• Sample preparation and conditioning (temperature/humidity and specimen dimensions) to ensure repeatable test results.
• Mechanical testing: tensile strength, elongation at break, and related dimensional checks.
• Waterproofing performance: water resistance under pressure and water tightness tests (including procedures for applying pressure and inspection criteria).
• Low-temperature flexibility (temperature of flexibility on a beam) and heat resistance checks for service temperature assessment.
• Impact resistance / drop-weight impact and subsequent waterproofness testing to assess resistance to mechanical damage.
• Water absorption, mass per unit area and related physical-property measurements used for acceptance and classification.

Typical use and users

Primary users include materials testing laboratories, manufacturers of rolled roofing and membrane waterproofing products, construction contractors performing acceptance testing, regulatory bodies and quality control departments. The standard is applied for product development testing, factory production control, incoming inspections and comparative evaluation of materials for roofing and waterproofing projects.

Related standards

GOST 2678-94 references and is used alongside other national and interstate standards for construction materials and test methods (examples: earlier national GOST versions that it replaced, related GOST/EN test methods for tensile and waterproofing performance, and product specification standards in the roofing sector). National catalogues list related GOST numbers for mechanical, thermal and safety tests used in conjunction with 2678-94.
