SIST EN 13305:2009

SIST EN 13305:2009 is the Slovenian adoption of EN 13305:2009. It gives a framework for specifying hard industrial bitumens used mainly in flooring, varnishes, mineral rubber, roofing and mastic, so suppliers and clients can agree on grades and test criteria.

What does SIST EN 13305:2009 specify?

SIST EN 13305:2009 specifies how to classify and describe hard industrial bitumens by softening point class and how to link those classes to test methods. It is a specification framework, which makes it useful for quality agreements between supplier and client.

The document is organized into a foreword, Scope, Normative references, Properties and test methods, and Typical grades. The main technical content is in Clause 3 and Clause 4, where the required properties and the grade designations are set out.

What are the key requirements of SIST EN 13305:2009?

The key requirement in SIST EN 13305:2009 is that hard industrial bitumens are graded by the limits of the ring and ball softening point, expressed as multiples of 5 and marked with an H prefix. In practice, the grade name itself tells buyers and laboratories the softening-point class to specify and test.

Property limits and methods in Clause 3

• Ring and ball softening point is measured to EN 1427, with a tolerance of ± 5 of the mid-point value. This is the main classification property, so it is the first value to check when choosing a grade.
• Penetration at 25 °C is measured to EN 1426. The note says the test may need to be carried out at 40 °C because of the precision of the method and the specification limits, which matters when the material is very hard.
• Solubility in toluene is measured to EN 12592, with a minimum of 99.0 %. This helps confirm the material is sufficiently bituminous and not excessively contaminated with insoluble matter.
• Loss in mass after heating is measured to EN 13303. The table marks this property as NR, meaning it is not a required limit in the framework unless supplier and client agree a value.
• Flash point is measured to EN ISO 2592 and must be greater than 250 °C. This gives a practical check on handling and storage safety during heating and processing.
• Density is measured to EN 15326. The table marks this property as NR, so it can be agreed between the contracting parties when density matters to the application.

How the grades are stated in Clause 4

SIST EN 13305:2009 lists typical grades such as H 80/90, H 85/95, H 90/100, H 100/110 and H 155/165. The example in the document shows that a designation such as H 85/95 means the product softening point lies between 85 °C and 95 °C. In practice, this gives a common shorthand for ordering, checking certificates and comparing deliveries.

What terms does SIST EN 13305:2009 define?

Hard industrial bitumens are the bituminous products covered by the framework, intended mainly for industrial uses such as flooring and roofing materials.

Ring and ball softening point is the temperature property used to classify the material into grades; it is the central specification value in the standard.

Mid-point value is the value that defines the ring and ball softening point class, and the tolerance in Clause 3 is given around that point.

H is the prefix used in the grade designation for hard industrial bitumens, followed by the softening-point class.

NR means no requirements. In the table, it shows that a property is listed but not fixed by a mandatory limit in the framework.

Penetration at 25 °C is a consistency measure used with EN 1426, and it helps indicate how hard or soft the bitumen is under standard test conditions.

Who uses SIST EN 13305:2009?

SIST EN 13305:2009 is used by producers of hard industrial bitumens, buyers and specifiers in flooring, varnishes, mineral rubber, roofing and mastic, and laboratory staff carrying out the linked test methods. Quality managers use it to write product agreements, compare deliveries and keep supplier-client specifications aligned. It is also useful for anyone who needs to name a grade unambiguously in technical documents or purchase specifications.

What changed in SIST EN 13305:2009 from the previous edition?

SIST EN 13305:2009 supersedes EN 13305:2003.

Which standards are used with SIST EN 13305:2009?

• EN 1426 - determines needle penetration, used here for penetration at 25 °C.
• EN 1427 - determines the ring and ball softening point, the main grading method in this standard.
• EN 12592 - determines solubility, used to check the toluene-soluble fraction.
• EN 13303 - determines loss in mass after heating of industrial bitumen.
• EN 15326 - measures density and specific gravity by the capillary-stoppered pyknometer method.
• EN ISO 2592 - determines flash and fire points by the Cleveland open cup method.

What does the SIST EN 13305:2009 document contain?

The document centers on one property-and-test-method table that links each specified characteristic to a test standard, unit and limit or tolerance. It also includes a short list of typical grades and an example showing how to read a grade designation. The foreword records the preparing committee, the adoption status in CEN member countries, and that the standard replaces EN 13305:2003.
