ČSN EN ISO 28721-2 This document specifies requirements for the resistance of chemical enamels to chemical attack and thermal shock, as well as their designation, for ordering purposes. It is applicable to enamels used in glass-lined apparatus, piping and other components, primarily used in process equipment in chemical plants, which are applied on to low-alloy carbon steels substrates. NOTE - The main criteria for assessing enamel quality are its resistance to chemical attack and thermal shock, and the structure of the cover coat enamel.

ČSN EN ISO 8744 This document specifies the characteristics of taper grooved pins with full-length progressive grooves (with closed end at the insertion side), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following function: locking together two or more parts, with an easy installation (due to its shape) and a high level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

ČSN EN ISO 8745 This document specifies the characteristics of taper grooved pins with half-length progressive grooves (with close-end at the insertion side), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: - positioning or guiding, and - relative rotation of the assembled parts, with an easy installation (due to its shape) and a medium level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

ČSN EN ISO 8740 This document specifies the characteristics of parallel grooved pins with chamfer point and full-length diamond grooves (with open ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following function: locking together two or more parts, with an easy installation (due to the chamfer point) and a highest level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.)

ČSN EN ISO 8741 This document specifies the characteristics of reverse-taper grooved pins with half-length progressive grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: - positioning or guiding, and - relative rotation of the assembled parts, with an easy installation (due to its shape) and a medium level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

ČSN EN ISO 13672 This document specifies the characteristics of parallel grooved pins with half-length diamond grooves (with closed ends), in steel and stainless steel, and with nominal diameters 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: - positioning or guiding, and - relative rotation of the assembled parts, with a more significant insertion force (due to its shape) and a high level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

ČSN EN ISO 8746 This document specifies the characteristics of grooved pins with round head, full-length diamond grooves and pilot point or chamfered point, in steel and stainless steel, and with nominal diameter 2 mm to 20 mm. These grooved pins are designed to fulfil the main following function: locking together two or more parts, with the easiest installation (due to the pilot or chamfer point) and a highest level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

ČSN EN ISO 8747 This document specifies the characteristics of grooved pins with countersunk head and full-length diamond grooves and pilot or chamfer point, in steel and stainless steel, and with nominal diameter 2 mm to 20 mm. These grooved pins are designed to fulfil the main following function: locking together two or more parts, with the easiest installation (due to the pilot or chamfer point) and a highest level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.
