109 national and interstate documents on standardization came into force in the beginning of December 2021. Series of standards on gas distribution systems, earth-moving machinery, tractors and machinery for agriculture and forestry are among these documents.
Now we will elaborate on the documents that became effective for the first time.
GOST R 59552-2021 «Major mobile communication functions for person with hearing disabilities. General requirements»
Due to the development of new technological capabilities modern mobile phones for people with hearing disabilities must have functions and options which satisfy necessary needs in communication, calling emergency services, carrying out of videoconferences, making orders of services, navigation, increasing the sound.
National standard sets requirements for the parameters of mobile devices with the function of videoconferencing and navigation.
Various parameters such as voice control, synthesizer of Russian speech, video camera with autofocus, motion sensor and other functions are required.
Parameters of the device with a text output with a function of videoconferencing and navigation for people with hearing disabilities are due to the need to use various digital social services online that do not require hearing and speech while characteristics of video conference are necessary for communication with an operator of the dispatch service which is carried out with the use of Russian sign language.
Navigation maps helps a person with hearing disabilities to navigate on the location, various messengers facilitate communication without use of hearing and speech.
GOST R 59543-2021 «Prosthetics and orthotics. Functional deficiencies. Classification, basic parameters, types and description of orthopedic devices (orthoses) for lower limbs in flaccid and spastic paresis and paralysis»
Such medical devices are applied as one of the components during the process of complex rehabilitation.
Orthopedic devices for lower limbs are classified according to the following features - age related ones, in relation to the degree of damage and according to the segments, joints of the body that are covered by these devices, dynamic characteristics aimed at filling motor functions.
Devices are designed for feet, whole leg, lower limbs and trunk, ankle, knee and hip joints depending on the affected area of lower limbs.
GOST R 59555-2021 «Layout profile products from wood-polymeric composite. Specifications»
This standard applies to products made by the method of extrusion from a composition based on thermoplastic polymers. It is intended for outdoor use and application as finishing materials for construction, reconstruction of buildings and structures for various purposes.
Method of extrusion is a technology of obtaining the goods with the method of pushing of the viscous melt of a material or thick paste through an extrusion hole.
Method of co-extrusion is a way of combined (simultaneous) extrusion that provides obtaining the profile consisting of two or more heterogeneous materials (commodity compositions) received from an extruding press.
Profiles can be monolithic and solid depending on structural design.
Profiles are divided into monostructural ones with top coat made by the method of co-extrusion according to the type of wall surfaces, extrusion options and coverage type.
Rates of mechanical properties of profiles should comply with minimal values of density, pressure, bending failure stress, tensile strength etc. For example, 1000 Kg/CM, 30 MPa, 12 MPa etc.
Main raw material for manufacturing of products should be wood flour with a content of at least 30% of the mass of base material and primary polymer material used during manufacturing of profile products.
