Your complete guide to the international ceramic tile product standard, trusted by manufacturers, suppliers, and procurement bodies worldwide.
Ceramic tiles are one of the most widely used construction materials in the world, and the expectations placed on their quality, durability, and consistency have never been higher. ISO 13006 is the internationally recognised standard that defines how ceramic tiles are classified, characterised, and marked, giving manufacturers, specifiers, and buyers a common technical language and a reliable framework for product conformity. Pacific Certifications supports ceramic tile manufacturers in demonstrating compliance with ISO 13006 through accredited quality management system certification and product conformity assessment services.
ISO 13006 is the international standard for ceramic tiles, developed by the International Organization for Standardization. It establishes definitions, classification systems, performance characteristics, testing methods, and marking requirements for ceramic tiles used in floor and wall applications. Rather than a management system standard, ISO 13006 is a product standard, meaning it defines what a ceramic tile product must be, how it must perform, and how it must be identified and labelled for the market.
The current version, ISO 13006:2018, consolidates and updates the classification and performance requirements for ceramic tiles across a comprehensive range of product types, manufacturing methods, and application environments. It works in conjunction with a series of ISO 10545 test method standards that define how each performance characteristic is measured and verified.
ISO 13006 classifies ceramic tiles according to two primary criteria. The first is the method of forming, distinguishing between extruded tiles produced by forcing a plastic mass through a die and pressed tiles produced by pressing a powder or granulate in a mould. The second is water absorption, which determines the tile’s density and suitability for different applications, ranging from fully vitrified porcelain tiles with very low water absorption through to more porous wall tile products. These two criteria together define the product group to which a tile belongs and the performance requirements it must meet.
The standard is relevant to any organisation involved in the manufacture, supply, specification, or procurement of ceramic tiles, including tile manufacturers, importers, distributors, architects, specifiers, construction companies, and quality assurance bodies. Compliance with ISO 13006 is increasingly expected in international procurement, construction contracts, and regulatory frameworks across major markets.

ISO 13006 defines technical requirements rather than organisational processes. Its framework covers the following core areas:
The standard establishes precise definitions for ceramic tiles and related terms, ensuring consistent interpretation across manufacturers, specifiers, and markets worldwide.
Tiles are classified by forming method and water absorption group, creating a matrix of product groups each with defined performance requirements. Understanding your product's classification is the starting point for demonstrating conformity.
The standard defines the physical, mechanical, chemical, and thermal characteristics that tiles in each product group must meet or exceed, including dimensional tolerances, surface quality, breaking strength, slip resistance, frost resistance, and chemical resistance.
Performance characteristics are measured using the ISO 10545 series of test methods, which define standardised procedures for each property. Conformity with ISO 13006 requires testing in accordance with these methods.
Tiles and their packaging must be marked with specific information including the manufacturer's name or trademark, product group classification, nominal dimensions, and other relevant product data. Accurate marking is a compliance requirement, not just a commercial practice.
Manufacturers must demonstrate that their products consistently meet the performance requirements of the relevant product group through appropriate testing and quality control processes.
ISO 13006 organises ceramic tiles into product groups based on forming method and water absorption, each with defined performance requirements.
| Classification Criteria | Categories |
|---|---|
| Forming Method | Group A: Extruded tiles / Group B: Dry-pressed tiles / Group C: Other methods |
| Water Absorption | Group I: Water absorption up to 3% / Group IIa: 3% to 6% / Group IIb: 6% to 10% / Group III: Over 10% |
| Product Group | Forming Method | Water Absorption | Common Product Type |
|---|---|---|---|
| BIa | Dry-pressed | Up to 3% | Porcelain tiles, fully vitrified |
| BIb | Dry-pressed | Up to 3% | Semi-vitrified pressed tiles |
| BIIa | Dry-pressed | 3% to 6% | Fine stoneware tiles |
| BIIb | Dry-pressed | 6% to 10% | Semi-porous pressed tiles |
| BIII | Dry-pressed | Over 10% | Wall tiles, earthenware |
| AIa/AIb | Extruded | Up to 3% | Extruded stoneware, pavers |
| AIIa/AIIb | Extruded | 3% to 10% | Extruded floor tiles |
| AIII | Extruded | Over 10% | Extruded wall and roof tiles |
ISO 13006 defines a comprehensive set of performance characteristics that tiles in each product group must meet, tested in accordance with the ISO 10545 series.
| Characteristic | Relevance |
|---|---|
| Dimensional Tolerances | Length, width, thickness, straightness, rectangularity, and surface flatness. |
| Surface Quality | Visible defects assessed against defined grading criteria. |
| Water Absorption | Determines product group classification and suitability for application. |
| Breaking Strength | Minimum force required to break a tile, relevant to structural integrity. |
| Modulus of Rupture | Stress at which a tile fractures, applicable across product groups. |
| Scratch Hardness | Resistance to surface scratching using the Mohs scale. |
| Resistance to Deep Abrasion | For unglazed tiles, resistance to surface wear under abrasive conditions. |
| Resistance to Surface Abrasion | For glazed tiles, assessed across five grades of wear resistance. |
| Slip Resistance | Friction coefficient relevant to safety in floor tile applications. |
| Frost Resistance | Ability to withstand freeze-thaw cycles without damage. |
| Chemical Resistance | Resistance to household chemicals, pool chemicals, and acids or alkalis. |
| Thermal Shock Resistance | Ability to withstand sudden temperature changes without cracking. |
Everything you need to prepare for ISO 13006 certification, in one place.
ISO 13006 defines what your ceramic tile products must achieve. ISO 9001 certification provides the independently verified management system framework that demonstrates how your organisation consistently achieves it. Together, they represent a complete quality assurance picture for ceramic tile manufacturers.
A certified ISO 9001 Quality Management System gives regulators, specifiers, and buyers confidence that product conformity with ISO 13006 is not the result of a one-off test, but of a structured, audited, and continuously improved system for managing quality at every stage of design, production, testing, and distribution.
Pacific Certifications certifies ceramic tile manufacturers and suppliers against ISO 9001:2015, providing accredited, globally recognised certification that supports and strengthens your ISO 13006 product conformity credentials.
The path to certification balances system building with rigorous auditing.
Submit your application and tell us about your organisation, the ceramic tile products you manufacture or supply, and your current quality management arrangements.
Before the formal audit begins, review your existing quality management practices and product testing records internally against ISO 9001 requirements and ISO 13006 product conformity requirements to identify and address any gaps.
A documentation review to confirm your Quality Management System, product testing records, and ISO 13006 conformity documentation are adequately developed and ready for the main assessment.
Our auditor evaluates whether your QMS is fully implemented and effective, including a review of your product classification records, testing programme, marking practices, and quality control processes.
Upon successful completion, your ISO 9001 certificate is issued, valid for three years, supporting your ongoing ISO 13006 product conformity programme.
Annual surveillance audits maintain your certification, followed by full recertification at the end of the three-year cycle.
For a standard ceramic tile manufacturer, the combined QMS certification and product conformity process typically follows a ten-week timeline.
| Week | Activity | Core Milestones & Focus Areas |
|---|---|---|
| Week 1 | Application & Scoping | Submit your application and define the scope covering tile product ranges, manufacturing processes, and sites involved. |
| Week 2 | Gap Analysis | Internally review existing QMS documentation and product testing records against ISO 9001 and ISO 13006 requirements. |
| Weeks 3-4 | QMS and Conformity Implementation | Develop or refine quality management processes, complete product classification documentation, and ensure testing records are in place. |
| Weeks 5-6 | Stage 1 Audit | Our auditor reviews your QMS documentation, product classification records, and ISO 13006 conformity documentation to confirm readiness. |
| Weeks 7-8 | Stage 2 Audit | Full on-site evaluation of your QMS implementation, production controls, testing programme, and marking practices. |
| Week 9 | Technical Review | Address any findings, close non-conformities, and finalise the certification review. |
| Week 10 | Certificate Issuance | Receive your accredited ISO 9001 certificate supporting your ISO 13006 product conformity programme. |
Note: The timeline is indicative and may vary depending on the number of product ranges, manufacturing sites, complexity of production processes, and completion of any corrective actions required.
Costs vary depending on the size of your organisation, the number of manufacturing sites, the range of tile products covered, and the complexity of your quality management and testing arrangements. Organisations integrating ISO 9001 certification with product conformity assessment will generally find a combined programme more efficient and cost-effective than addressing each separately.

ISO 13006 is the international product standard for ceramic tiles. It defines how tiles are classified, what performance characteristics they must meet, how those characteristics are tested, and how products must be marked. For manufacturers, compliance is increasingly a baseline requirement for accessing international markets, meeting procurement specifications, and demonstrating product quality to buyers and regulators.
ISO 13006 is a product standard. It defines technical requirements for ceramic tile products rather than management system processes. It works alongside ISO 9001, which is the management system standard that demonstrates how an organisation consistently produces conforming products. Pacific Certifications certifies organisations against ISO 9001, which directly supports and strengthens their ISO 13006 product conformity programme.
ISO 13006 defines the classification system, performance requirements, and marking requirements for ceramic tiles. The ISO 10545 series define the specific test methods used to measure and verify each performance characteristic. Conformity with ISO 13006 requires testing in accordance with the ISO 10545 methods relevant to the product group.
Tiles are classified by two criteria: forming method, which distinguishes between extruded tiles and dry-pressed tiles, and water absorption, which ranges from very low absorption porcelain tiles through to more porous wall tile products. These two criteria together determine the product group and the performance requirements that apply.
The standard covers a comprehensive range of characteristics including dimensional tolerances, surface quality, water absorption, breaking strength, modulus of rupture, scratch hardness, abrasion resistance, slip resistance, frost resistance, chemical resistance, and thermal shock resistance. The specific characteristics required depend on the product group.
ISO 9001 certification provides independently verified evidence that your organisation has a structured quality management system in place to consistently produce tiles that meet ISO 13006 requirements. It demonstrates that product conformity is the result of a managed, audited system rather than a one-off test result, which is increasingly what clients, specifiers, and regulators expect to see.
Yes. Pacific Certifications provides ISO 9001 certification for ceramic tile manufacturers and suppliers, which directly supports your ISO 13006 product conformity programme. Contact our team to discuss how we can structure a certification programme that addresses both your management system and product conformity objectives.
The standard itself is voluntary, but compliance is increasingly required by procurement specifications, construction contracts, import regulations, and retail supply chain requirements in major markets. In practice, manufacturers that cannot demonstrate ISO 13006 conformity face significant barriers to accessing premium and international markets.
Product conformity under ISO 13006 should be maintained on an ongoing basis through your quality control programme. ISO 9001 certification, which supports your conformity programme, is valid for three years with annual surveillance audits to confirm your quality management system remains effective.
Non-conforming products must be identified, controlled, and not placed on the market as conforming until they meet the applicable requirements. A certified ISO 9001 Quality Management System includes documented processes for managing non-conforming products and implementing corrective actions to prevent recurrence, which is one of the most practical reasons to have both product conformity and management system certification in place.
