The library resources comprised standards, technical regulations and documents on conformity assessment systems. The collection is available in the form of hardcopy, microform and machine-readable form.


  1. Standards: The main collection of the TISI library are standards comprising:  
    Thai standards (TIS and TCPS)
    Foreign standards: Standards published by ISO members such as ANSI, BS, DIN, JIS etc. JIS -or- Standards developed by business associations and organizations  such as API, IEEE, JASO, etc.
    Regional standards which are standards developed and used by countries in the same region such as European standards (EN, EEC, ETSI,), standard of the Middle East countries (GS), etc.
    International standards which are standards developed by international organizations such as IEC, ISO, ITU, CODEX.
  2. Technical Regulations of Thailand and of some WTO member countries.
  3. Documents on Certification Systems / Conformity Assessment of Thailand and of some foreign countries.
  4. Reference and textbooks such as standards catalogues of various countries (the standards catalogues which are publications containing the list of standards developed by different standards organizations are useful tool in searching for the requested standards), directories, yearbooks, government publications, dictionaries and encyclopedia.
  5. Journals TISI library has approximately more than 300 Thai and foreign journals in various subjects such as standardization, quality, education , science and technology and general subjects.
  6. Databases on standards At the moment, apart from its own databases on Thai standards and on library collection, the library also subscribes to foreign databases on standards, i.e. approximately 50 databases on CD-ROM/DVD and 14 databases on microfiches. These databases are periodically update to ensure that the information is complete and current.

TISI library maintains an up-to-date collection of Thai and foreign standards, technical regulations and conformity assessment as well as related documents in the printed and non-printed forms. The classification systems used in the library are as follows:
1. For books: Dewey Decimal Classification - DDC
2. For standards: International Classification for Standards - ICS
3. For special publications of standards institutes and government publications: Classification system developed by the library itself
The books and documents in the library are shelved according to their types and are provided with their indexes to assist searching. Moreover, details of library collection can also be retrieved from library databases and CD-ROM/DVD databases.

ICS - The International Classifcation for Standards**
  Formerly, standards are usually classified by the International Organization (ISO) and various standards bodies according to the Universal Decimal Classification System (UDC). However, since the UDC system had been found to be too complicated for standards, a new system known as the ** International Classifcation for Standards (ICS) was developed by the ISO Committee on Information and System and Services (INFCO) specifically for standards. From its first publication in 1996, the ICS the has been revised regularly to embrace all fields of standards.
  Like the UDC, the ICS is a hierarchical classification system but it is provided with more flexibility and ease for use. The system comprises 3 levels as follows:
    Level 1To be divided into 40 fields which are indicated by a two-digit notation.
    Level 2 The fields are subdivided into 391 groups which are indicated by a three-digit notation.
    Level 3The groups are subdivided into 895 sub-groups which are indicated by a two- number, separated by a point.
  ICS has been developed to be used by standards libraries and information centres in the classification of standards and related documents, in the preparation of standards catalogues, indexes, bibliographies as well as in the creation of standards databases.
