37 national and interstate standards came into force in early October 2020. They include a series of documents on welding and related processes, barley standards, production automation systems and others.
GOST R 58927-2020, Fuel dispensers. General specifications, applies to fuel dispensers designed to measure the amount of gasoline or diesel fuel spilled into car tanks and consumer containers at gas stations and complexes. The standard provides the main parameters of fuel dispensers and their values. The document contains requirements to the design of fuel dispensers. In particular, before each dispensing of petroleum products, it is necessary to zero the readings of the one-time record indicator. According to the national standard, the fuel dispenser provides the delivery of gasoline at a temperature from minus 40 ° C to plus 35 ° C and diesel fuel from minus 40 ° C to plus 50 ° C. The column should function normally under the influence of ambient temperature from minus 40 ° C to plus 50 ° C and relative air humidity from 30% to 100%. Criteria for refusal are given in the document. The full average service life is at least 12 years. GOST pays great attention to the description of testing methods for fuel dispensers, the equipment for their conduct, as well as the conditions and order of final rejection.
GOST 34636-2020, Tube billet. General specifications, was prepared on the basis of the same-name national standard ten years ago. GOST applies to continuously cast and hot-deformed tubular billets made of unalloyed and alloyed steel intended for production of seamless pipes. In the manufacture of tube billets can be used oxygen-converter, arc, vacuum-induction methods of steel melting, as well as electroslag, vacuum-arc and plasma-arc methods of its melting. Continuous cast tube billet is supplied with a diameter of 145 to 600 mm. Hot-deformed - 70 to 410 mm. Customer must agree with the manufacturer the methods of melting, remelting, casting and the presence or absence of secondary steel processing. Otherwise, the manufacturer selects the method of production and the parameters of the tube blanks by himself.
