The general technical delivery conditions specified in EN apply in addition to the spocifications of this European Standard, unless otherwise specified in this Eu- ropean Standard, 1.

Part 1 Stee! Annex B. Definitions 3. Product forms: See EN for definitions. Types of heat treatment: See EN for defini- tions. The requirements given in tables 1 to 4 apply with respect to the chemical composition in the cast analysis. Itis therefore advisable to draw on the available experience in the use of the steels. Page 4 EN 8. As they do not have a pronounced transition temperature, which is characteristic of other steels, they are also Useful for application at cryogenic temperatures.
If more detailed requirements regarding the surface quality are to be satisfied, these shall be agreed at the time of ordering, taking EN as the basis where appropriate. In view of tis, compliance with these requirements need not be verified by specific tests unless otherwise agreed.

If it has been agreed that Impact tests be carried out, the samples shall be taken from the same location. The samples shall be taken from products in their as deliv- fered condition. If agreed, samples from bars may be taken before straightening. For samples to be given a simulated heat treatment the conditions for annealing, hardening and tempering shall be agreed, 9.
In cases of doubt and in referee cases, Such test ploces must be used The tensile strength and elongation after fracture shall bo determined and for fertic, martensite, precipitation hard fring and austentc-ferrtic steels, also the 0, proof Strength ang for austenitic steels the 0.
The average obtained from three test pieces is considered to be the test result cf. EN Page 16 EN Table 8: Mechanical properties at ambient temperature for martonsitic steels in the heat-treated condition see table A. ABi8Ue d 96 soo.
