Standardization

Standardization is an activity that determines the provisions for solving existing or potential problems to achieve optimal levels. Standardization involves compiling, publishing and using of standards. The benefits of standardization are reflected in improving the consistency of products, processes, services, methods, etc., in preventing trade barriers and facilitating technical cooperation.

Standardization Technical Committee EVS/TC 57 „Processing oil shale and oil shale product“ was registered  up to Estonian Centre for Standardization 25.05.2015.

The activities of the Technical Committee are supervised and managed by the Oil Shale Competence Center to develop sectoral standards.

The purpose of the creation of the Committee:

  • to identify industry standardization needs,
  • update current existing standards,
  • create new original standards,
  • share best practices with recognized experts
  • and develop international cooperation.

EVS/TC 57 scope: oil shale mining and processing technologies, production of shale oil and oil shale chemistry, oil shale energy, treatment of residual substance and waste products

Standardization Technical Committee EVS/TC 57 „Processing oil shale and oil shale product“ work programme: work programme 2021.

EVS/TC 57 Committee members:

  1. Estonian Environmental Research Centre
  2. Viru Keemia Grupp AS
  3. Eesti Energia AS
  4. Kiviõli Keemiatööstuse OÜ
  5. Tallinn University of Technology
  6. Oil Shale Competence Center of TalTech Virumaa College
  7. Estonian Mining Society/ MTÜ Eesti Mäeselts

Oil Shale Competence Center provides assistance and consultancy to businesses in

  • drafting sectoral standards,
  • the preparation of working groups for compilation of standard draft by the EVS/TC 57 "Processing oil shale and oil shale product".

The intention to compile a standard draft is to inform the Technical Committee in order to enable the drafting of the standard to be included into the work programme.

International standards has been taken over by reprint method

EVS-ISO 1928:2016

Solid mineral fuels. Determination of gross calorific value by the bomb calorimetric method and calculation of net calorific value.

The international standard has been taken over in English with Estonian comments. The Standard EVS-ISO 1928: 2016  contains modified English text of the international standard ISO 1928: 2009 "Solid mineral fuels for the determination of the calorific value".

 The modified edition of the standard concerns the determination of the calorific value of solid mineral fuels, including the calorific value of oil shale. In this standard, the determination of the upper calorific value of oil shale by the calorimetric bomb method and the calculation of the lower calorific value, which were lacking in the international standard, have been included as Estonian comments.

EVS-ISO 562:2018

Solid mineral fuels. Determination of chlorine using Eschka mixture.

The international standard has been taken over in English with Estonian comments. Standard  EVS-ISO 587:2018  contains modified English text of the international standard ISO 587:1997 „Solid mineral fuels - Determination of chlorine using Eschka mixture“.

The standard deals with the determination of chlorine content in oil shale, coal, brown coal, lignite and coke with Eschka mixture. The standard incorporates additions and amendments that allow to determine the chlorine content of oil shale and semi-coke on the basis of the standard.

EVS-ISO 587-MOD:2020 

Hard coal, cole and oil shale. Determination of volatile matter.

The international standard has been taken over in English with Estonian comments. Standard   EVS-ISO 562:2018 contains modified English text of the international standard ISO 562:2010 „Hard coal and coke. Determination of volatile matter“.

In the modified edition, additions have been supplemented to allow the volatile content of oil shale to be determined according to the standard. The transposition of the standard with comments and additions in the context of oil shale was necessary for better organization of the work of research laboratories.

EVS-ISO 334-MOD:2020

Solid mineral fuels. Determination of total sulfur. Eschka method.

The international standard has been taken over in English with Estonian comments.   The Standard EVS-ISO 334:2019 contains modified English text of the international standard 334:2010 „Solid mineral fuels. Determination of total sulfur. Eschka method“.

Modifications were added to the text to extend the scope of the standard in oil shale context and in its thermal treatment products, taking into account the specific characteristics of oil shale and oil shale products.

As an alternative method, an extraction method with water and some essential specifications for analysis were added.

The original Estonian standards have been prepared

EVS 940:2019

Burnt Shale for the  Plastic Industry. Specifications and conformity criteria.

Estonian standard in English

The original Estonian standard “Burnt shale for production of plastics. Specification and conformity criteria.“ prepared by the workgroup of EVS/TC 57 and has been published by EVS.

The proposal of  the new original Estonian standard preparation was submitted by the company Eesti Energia AS. The standard EVS 940:2019 applies to heat-treated oil shale or a mixture of oil shale with at least 70% oil shale.

Burnt oil shale is considered in the standard as a product that is used in the plastics industry as a filler in one of the components of plastic. This, in turn, necessitated by industry to submit requirements for this aggregate, its production control arrangements and the procedure for attesting conformity.

 The original Estonian standards have passed the new processing

EVS 664:2017

Solid fuels. Sulfur content. Determination of total sulfur and its bonding forms.

This is a new revision of the previous version of the standard EVS 664:1995 “Solid fuels. Sulfur content. Determination of total sulfur and its bonding forms.”

An important amendment compared with the previously described methods is the insertion of an apparatus method for total sulfur determination into the new version of the standard EVS 664:2017, and editorial corrections in the text.

EVS 668:2018

Oil shale. Determination of moisture.

This is a new revision of the previous version of the standard EVS 668:1996 “Kukersite oil shale. Determination of moisture”.

This new standard EVS 668:2018 “Oil shale. Determination of moisture” describes a two- and one-step method for total moisture content determination in oil shale, a method for analytical moisture determination and the procedure for samples preparation. According to the standard, moisture is determined both in the saleable oil shale sample and in the strata samples, in the drill cores, in enrichment residues and other oil shale samples taken and prepared according to the valid standard.

This standard is applied to oil shale deposits irrespective of the origin deposit location (not only for kukersite oil shale). Due to the extension of the scope of the standard to the analysis of oil shale in other mineral deposits in the world, the possibilities of using a hydrometer are also included to determine both analytical moisture and changes in the accuracy of moisture determination.
