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,

Põletatud põlevkivi plastitööstusele. Spetsifikatsioonid ja vastavuskriteeriumid. Standard published in Estonian. |
The original Estonian standard "Burnt shale for plastics industry. Specifications and conformity criteria" prepared by the WG created for EVS/TC 57 „Processing of Oil Shale and Oil Shale Products“. Specifications and Conformance Criteria' have been published. This Estonian standard is valid for thermally treated oil shale or its mixtures, where the proportion of oil shale is at least 70 % (hereafter burnt shale or BS). Burnt shale is used as a filler material in plastic. Burnt shale consists of clinker material, free lime, dehydrated calcium sulphate and a mixture of partially caked particles of the previously mentioned components and depending on its fineness is divided into the following product classes: Plastic BS – F; Plastic BS – M; Plastic BS |

Burnt Shale for the Plastic Industry. Specifications and conformity criteria. Estonian standard in English. |
The original Estonian standard "Burnt shale for plastics industry. Specifications and conformity criteria" English version. 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.

Naftasaadused ja samaväärsed tooted. Kütused (klass F). Destillaat- ja jääkkütused, Eesti põlevkiviõli spetsifikatsioon. Standard published in Estonian |
Estonian shale oil is a liquid product produced from kukersite oil shale through pyrolysis. Estonian shale oil is primarily used as liquid fuel or its blending component. The need to establish specification of Estonian shale oil is to define respective product based on its characteristic properties. Liquid fuels are often blended together from different components. Standardised motor fuels as final products have to meet certain quality requirements. As Estonian shale oil is used as a blending component in fuel oils and bunker fuels the need has arisen to define characteristic properties of shale oil fractions. |

Põlevkivi. Niiskuse määramine. Standard published in Estonian |
This is a 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.

Põlevkivi. Tuhasuse määramine. Oil shale. Determination of ash Standard in Estonian |
In the first version EVS 669:1996 "Determining the ashiness of kukersite oil shale" only Estonian oil shale was under consideration. The renewed standard deals with the method of determining the ash content of oil shale from different deposits and its heat treatment and burning residues, therefore the title has been changed to "Oil shale. Determination of ash". The standard has undergone structural changes, added updates and edited text. The following chapters have been added: "Terms and definitions", "Nature of methods", "Sample preparation", "Calculation of results", “Appendix A” and "Literature".

This standard EVS 670:2023 is a revision of the previous version EVS 670:1998. The renewed standard deals with commercial oil shale as a product and the norms and permissible deviations of its quality characteristics, presents general requirements for the lower calorific value of commercial oil shale and its calculation, and requirements for general humidity. The standard no longer deals in detail with commercial oil shale classes or quality groups, which are determined according to the documents listed under the standard references and specified in purchase and sale agreements. The structure of the standard is aligned with the requirements of the EVS GUIDE 2:2018 "Preparation of Estonian standards and standard documents similar to the EVS standard".
