Full title and description

St ISO 8336-2017 — Fibre‑cement flat sheets: product specification and test methods. This international standard specifies inspection and laboratory test procedures and acceptance conditions for fibre‑cement flat sheets used as external and internal wall and ceiling finishes and as backing sheets in building applications.

Abstract

ISO 8336:2017 sets out the types of tests, sampling and acceptance criteria to assess the physical and mechanical properties of fibre‑cement flat sheets (for example: dimensional tolerances, thickness and mass per unit area, density, bending/flexural strength, water absorption and durability-related tests). It excludes sheets intended specifically for fire‑protection purposes and certain other product categories (for example, asbestos‑containing sheets, sheets with steel‑fibre reinforcement and fibre‑reinforced calcium silicate boards). The standard is primarily intended to support conformity assessment for building and cladding applications.

Scope

ISO 8336:2017 applies to fibre‑cement flat sheets intended for use as external or internal wall and ceiling finishes and as internal or external backing sheets. It specifies inspection and test methods and gives acceptance criteria for those applications. The standard does not cover sheets manufactured for fire‑protection purposes, nor does it include calculations for installation design (wind uplift, waterproofing, etc.). It also excludes certain product types such as Portland‑cement boards reinforced with wood particles, calcium‑silicate or cement boards for thermal insulation or fire protection, asbestos‑containing sheets, sheets with steel fibre reinforcement and fibre‑cement roofing slates.

Key topics and requirements

• Definition of product types and categories of fibre‑cement flat sheets and related terminology.
• Sampling procedures and frequency for inspection and laboratory testing.
• Dimensional and geometric requirements: length, width, thickness, straightness/flatness and permitted tolerances.
• Mass per unit area and bulk density measurement methods and limits.
• Mechanical performance tests including bending (flexural) strength / modulus of rupture and related acceptance criteria.
• Water absorption and moisture‑movement tests to evaluate performance in wet/dry cycles.
• Durability and weathering related tests (for example soak‑dry, heat/rain, freeze‑thaw where applicable) and acceptance indicators for visible defects or loss of performance.
• Resistance checks such as resistance to acidified water, mould growth, and pull‑through (nail head) resistance when applicable.
• Marking, packaging and product information required for conformity and traceability.

Typical use and users

Primary users are manufacturers of fibre‑cement flat sheets, independent test laboratories, construction product certifiers, building materials specifiers, architects and contractors involved in cladding, internal and external linings and backing sheet installations. Regulatory bodies and procurement teams also use the standard as a basis for product acceptance criteria in building projects.

Related standards

Standards often referenced alongside ISO 8336 include regional or complementary product standards and test methods for fibre‑cement products (for example EN standards for fibre‑cement flat and profiled sheets). Earlier and related ISO documents in the same topic series include the previous ISO 8336:2009 edition and other ISO/EN standards that cover profiled sheets, pipes or fittings made of fibre‑cement. Users commonly cross‑reference ISO 8336 with local building codes and product standards such as EN 12467 (fibre‑cement flat sheets) depending on jurisdictional requirements.

FAQ

Q: What is this standard?

A: ISO 8336:2017 is an international standard that specifies inspection procedures, laboratory test methods and acceptance criteria for fibre‑cement flat sheets used in building applications.

Q: What does it cover?

A: It covers product specification and test methods for flat fibre‑cement sheets — including dimensional checks, density and mass per unit area, bending (flexural) strength, water absorption and a range of durability‑related tests — and provides acceptance conditions for use as internal/external finishes and backing sheets. It excludes sheets for fire protection and several other specialized product types.

Q: Who typically uses it?

A: Manufacturers, test laboratories, certification bodies, architects, specifiers, contractors and procurement authorities who need harmonized test procedures and acceptance criteria for fibre‑cement flat sheets.

Q: Is it current or superseded?

A: ISO 8336:2017 is the current published edition (Edition 3) and it replaced ISO 8336:2009. The document is kept under periodic review by ISO.

Q: Is it part of a series?

A: Yes — ISO 8336 sits within a family of standards dealing with fibre‑reinforced cement products. Other related ISO and regional standards cover profiled sheets, roofing slates, pipes and fittings made from fibre‑cement as well as regional variations (for example EN standards) that may be used alongside ISO 8336 depending on local regulatory requirements.
