Designation and composition What the material is.
Grade and composition
The designation, standard and chemical composition limits.
Material designation
The material is named by a standard designation or a supplier grade.
- Which standard designation or supplier grade identifies the material?
- Which standard defines the grade, and in which edition?
Composition
The composition is stated as limits or nominal values per constituent.
- What composition limits does the specification set?
- Which constituents are registered substances with regulatory obligations?
Properties and processing How the material behaves and how it is made.
Property data
Mechanical, thermal and other properties with test conditions.
Tested properties
Each property value names its test standard, condition and temperature.
- Which test standard and conditions produced each property value?
- Are the values minimums, typical values or measured values?
Processing state
Heat treatment, temper or curing state that the properties depend on.
- Which processing state or temper do the properties refer to?
- Does processing change the material's designation?
Compliance and end of life Rules and safe handling over the life cycle.
Safety and compliance
Hazard information, restrictions and recyclability.
Regulatory status
Restricted substances, hazard communication and recycling routes are recorded.
- Does the material contain substances restricted or of very high concern?
- Which safety data sheet and recycling route apply?

What it is Filled
An engineered material is a material produced and specified for use, such as a steel grade, polymer, ceramic, composite or alloy, defined by its composition, processing and resulting properties. The subject is the material kind or grade as specified; a particular batch or lot, a finished product made from it and a pure chemical substance in its regulatory sense are separate subjects.
Why it exists Filled
Engineered material grades defined by composition, processing and specified properties.
Distinguishing features Filled
- It is a specified grade or kind, not a physical batch, lot or part.
- Its properties depend on processing state as much as on composition.
- Distinct from a chemical substance in regulatory terms, though its constituents may be registered substances.
- Distinct from a mixture or formulation, which is a recipe of ingredients rather than a structural material grade.
What robots and AI may and may not do Filled
Must not
- Present typical values as guaranteed minimums.
- Declare two grades equivalent without a cited equivalence basis.
- Approve a material substitution in a safety-relevant design.
- Omit hazard information from a safety data sheet when passing it on.
- Invent property values that no test or specification supports.
Only with a human decision
- Qualifying a material for a structural, medical or safety-critical use.
- Approving a substitution of one material grade for another.
- Signing a declaration of conformity.
May
- Look up designations, composition and property data with their test conditions.
- Compare grades across equivalent standards with stated caveats.
- Check a material against restricted substance lists.
Moral aspects Filled
- Wrong material data can lead to structural failure and injury.
- Workers handling dusts, fibres and nanomaterials face exposure risks.
- Material choices drive embodied carbon and end-of-life waste.
Who is affected
- Users of products made from the material
- Workers in production and processing
- Designers and engineers
- Communities near production and disposal sites
Owners Filled
Steward
A standards body or materials producer that defines the grade and maintains its specification.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- A material is identified by its standard designation, such as a steel name or number under a national or international standard, or by a supplier grade name.
- Constituent substances are identified by CAS Registry Numbers or EC numbers.
Direct properties required Filled
- Density in kilograms per cubic metre.
- Tensile and yield strength in megapascals, at a stated temperature and test standard.
- Elastic modulus in gigapascals.
- Thermal conductivity in watts per metre kelvin and coefficient of thermal expansion per kelvin.
- Hardness on a named scale, such as Vickers or Brinell.
Recognition required Filled
- A material is recognised from markings, certificates, spectrometric composition analysis and property tests.
- Often confused with a similar grade under a different standard or with an unverified substitute.
Capabilities and actions required Filled
- Properties can be measured by standard tests.
- Grades can be mapped across standards with equivalence tables.
- Composition can be verified by chemical analysis.
Hazards and failure modes required Filled
- Inhalation of dusts, fibres or nanoparticles during processing.
- Structural failure from counterfeit or wrongly specified material.
- Restricted substances in the composition.
Standards and interfaces required Filled
- Inspection documents under EN 10204 for metallic products.
- Safety data sheets under the Globally Harmonized System of classification and labelling.
- ISO 6892-1 tensile testing of metallic materials.
Context of use required Filled
- Used in design, manufacturing, construction and procurement.
- Subject to chemical regulation such as REACH where constituents are registered substances.
