SIST EN 13892-1:2003

SIST EN 13892-1:2003 is the Slovenian standard identical to EN 13892-1:2002, published by SIST. It specifies how to sample screed materials and how to make and cure test specimens for later testing. It is used for cementitious, calcium sulphate, magnesite and synthetic resin screed materials in manufacturing, site work and laboratory testing.

What does SIST EN 13892-1:2003 specify?

SIST EN 13892-1:2003 sets the sampling and specimen-preparation method for screed materials, then links those specimens to later test methods. The standard covers dry material, freshly mixed material, and pre-packaged products ready for mixing.

The scope includes samples taken by the manufacturer, contractor, client or another interested party, including dispute cases and fully mixed product before laying. Mastic asphalt screed material is handled by EN 12697-20 and EN 12697-21, and special synthetic resin screed material may require manufacturer-specific methods.

The document is organized into clauses on:

• Scope
• Normative references
• Sampling
• Mixing
• Making test specimens
• Curing
• Test report
• Bibliography

What are the key requirements of SIST EN 13892-1:2003?

Clause 3 requires representative sampling of the average material. In practice, the sample has to reflect what is actually being supplied or laid, so the test results can be trusted in production checks or disputes. The test report also has to identify whether the sample was a spot sample or a composite sample.

Clause 3 also sets handling rules for fresh or sensitive material. Samples that may change in air are placed in airtight containers quickly, and specimens should be prepared as soon as possible, within the manufacturer’s working time. This matters because moisture loss, unwanted water gain or time delay can change the test outcome.

Clause 4 requires mixing to follow the manufacturer’s instructions, including the stated water or liquid content. If a range is given, the standard uses the middle value, and the declared consistency should be achieved. The mixing equipment can be the EN 196-1 mixer, a concrete mixer, or another mixer when the product instructions allow it.

Clause 4 also links mixing quantity to the mixer type through Table 1. That helps the user prepare a batch large enough for the later tests without wasting material or underfilling the apparatus. The temperature of the room, equipment and materials is also controlled so mixing is repeatable.

Clause 5 covers specimen moulds and forming. The mould material should be steel or another non-reactive material, and the size and shape depend on the later test in Table 2. For a concrete substrate, the standard requires a suitable tensile strength, and a bonding agent is used when the product instructions call for it.

Clause 5 also distinguishes between flowing and other screed materials. Flowing material is cast in one pour, while other materials are placed in layers and compacted, or prepared exactly as the manufacturer instructs. This matters because specimen density and surface finish affect strength, wear, bond and impact results.

Clause 6 sets curing and storage conditions before testing. The storage chamber must control temperature and relative humidity, and Table 3 links those conditions to the screed material type and storage stage. In practice, this is what makes specimens comparable from one laboratory or site to another.

Clause 7 requires a traceable test report. It records the product identity, supplier, batch reference, sampling place and time, sampling method, sample identification, mixing and curing details, and the date and signature of the report. That information is what allows later test results to be checked against the actual material and preparation history.

What terms does SIST EN 13892-1:2003 define?

• Screed material - the material sampled and prepared for later test as a floor screed or screed layer.
• Spot sample - a sample taken from one point or moment to represent that specific portion of material.
• Composite sample - a combined sample made from several increments to represent the average composition.
• Working time - the period within which the mixed material can still be prepared into specimens.
• Curing - controlled storage of test specimens before testing so their condition is stable and repeatable.
• Relative humidity (RH) - the moisture level in the storage chamber, which the curing conditions control.
• Synthetic resin screed material - screed material based on synthetic resin, treated separately in the curing and sampling guidance.

Who uses SIST EN 13892-1:2003?

SIST EN 13892-1:2003 is used by screed material manufacturers, contractors, clients, and testing laboratories. Manufacturers use it for production control and for samples taken before dispatch. Contractors and clients use it on site or during use, and laboratories use it to prepare specimens for strength, wear, hardness, bond and impact testing.

What changed in SIST EN 13892-1:2003 from the previous edition?

SIST EN 13892-1:2003 is identical with EN 13892-1:2002.

Which standards are used with SIST EN 13892-1:2003?

What does the SIST EN 13892-1:2003 document contain?

The document gives the working steps for sampling, mixing, making specimens and curing them before later testing. It includes apparatus lists, procedures for different mixers, and guidance for casting on a concrete substrate. Table 1 controls the batch size for mixing, Table 2 links specimen and mould geometry to the later test, and Table 3 sets storage conditions and curing time by screed material. The report section gives the traceability information needed for quality control, disputes and laboratory records.
