SIST EN ISO 13397-3:2000 is the Slovenian standard for H-type dental scalers, published by SIST and identical to EN ISO 13397-3:1996. It specifies the dimensions and design presentation for these hand instruments used to remove calculus and other accretions from tooth surfaces, mainly for manufacturers, inspectors, buyers and dental equipment users who need a common size reference.

What does SIST EN ISO 13397-3:2000 specify?

SIST EN ISO 13397-3:2000 specifies the dimensions for H-type dental scalers. The document focuses on a family of hand instruments and ties those dimensions to the drawings and measurement points used to check them in practice.

The standard is organized into four clauses: Scope, Normative references, Definitions, and Design and dimensions. Clause 4 is the core of the document, and it works together with ISO 13397-1 for general requirements.

What are the key requirements of SIST EN ISO 13397-3:2000?

SIST EN ISO 13397-3:2000 requires H-type dental scalers to conform to the designs shown in Figures 1 to 5 and to the dimensions in Table 1. In practice, this means a manufacturer cannot rely on general appearance alone - the instrument has to match the specified H-type form and size.

• Clause 4 links the part to ISO 13397-1. The general requirements for dental scalers are given in ISO 13397-1, so this part is used together with the base part of the series.
• The overall length is limited to 178 mm. This gives a clear upper limit for all designs, which matters for handling, packaging and dimensional inspection.
• Table 1 sets the dimensional profile for each H-type. The table identifies types H3 to H9 and distinguishes chisel, cleoid and sickle forms, so users can select and verify the correct instrument variant.
• Table 2 fixes how each dimension is measured. It defines the measurement point for blade width, blade thickness, blade length, blade height, shank height, length to first bend, radius of blade, blade angle and offset angle. This matters because the same instrument can only be checked consistently if everyone measures from the same reference points.
• Blade angle and offset angle have specific geometric meanings. The blade angle is taken relative to the centreline of the blade, shank or instrument as appropriate, while the offset angle is read in plan view at the first bend. This is important for comparing working shape, not just size.
• The document relies on defined terminology from ISO 1942-3. That keeps the instrument vocabulary consistent across dental standards and reduces ambiguity in specifications and purchasing documents.
• A measurement method from ISO 13397-1 is referenced for most dental hand instruments. This supports practical inspection and helps laboratories and quality teams use the same approach.

What terms does SIST EN ISO 13397-3:2000 define?

Dental scaler - A hand instrument used to remove calculus and other accretions from tooth surfaces.

Glaze surface - The working surface of the instrument that is formed during production of the cutting edge(s).

H-type - The family of dental scalers covered by this part, with variants shown as H3 to H9.

Blade angle - The angle between the glaze surface and the centreline of the blade, shank or instrument, depending on the measurement.

Offset angle - The angle, seen in plan view, between the shank centreline and a tangent line at the first bend.

Length to first bend - The distance from the datum point to the highest point on the first bend of the shank.

Who uses SIST EN ISO 13397-3:2000?

SIST EN ISO 13397-3:2000 is used by dental instrument manufacturers, quality control teams, test laboratories and procurement staff who need to specify or verify H-type scalers. It is also useful for dental equipment suppliers and buyers who compare products against a common dimensional standard before acceptance.

Which standards are used with SIST EN ISO 13397-3:2000?

• ISO 1942-3:1989 - Supplies dental vocabulary used for the terminology in this part.
• ISO 13397-1:1995 - Gives the general requirements for dental scalers and includes a measurement method in Annex A.
• ISO 13397-2 - Covers periodontal curettes, Gr-type, within the same instrument family.
• ISO 13397-4 - Covers dental excavators, Discoid-type, as another part of the series.

What does the SIST EN ISO 13397-3:2000 document contain?

The document contains the scope, two normative references, two definitions, and the dimensional specification for H-type dental scalers. Figures 1 to 5 show the instrument forms for the different H-types, including chisel, cleoid and sickle variants.

Table 1 lists the dimensional scheme for each type, and Table 2 explains the measurement points used for inspection. Together, these parts support design control, dimensional checking and product comparison in manufacture and quality assurance.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 13397-3 was prepared by Technical Committee
lSO/TC 106, Dentistry, Subcommittee SC 4, Dental instruments.
IS0 13397 consists of the following parts, under the general title
Periodontal cure ttes, dental scalers and excavators:
- Part 7: General requirements
- Part 2: Periodontal curettes - Gr-type
- Part 3: Dental scalers - H-type
4: Dental excavators - Discoid-type
- Part
It i s anticipated that additional types of instruments will form the subject
of future parts.
