This standard applies to LZ-TsNII railway lubricant with an additive composition intended for use in roller bearings of railway cars at temperatures from minus 60 to plus 100 °C.
Lubricant designation according to GOST 23258—UNa-Ka 6/10-3.
1. TECHNICAL REQUIREMENTS
1.1. LZ-TsNII railway lubricant must correspond to the composition specified below.
Lubricant composition, % (by weight):
Industrial castor oil according to GOST 6757 .....................................19±2
Construction air lime according to GOST 9179 .................................... 0.5±0.1
Technical caustic soda according to GOST 2263................................................. ......0.5±0.1 calculated until complete saponification of fats

Additive DF-11................................................... ............ ........................... 5±0.1
Spindle oil AU non-paraffin oils or oil AU
low sulfur oils or AC oil of sulfur oils...................................up to 100.
When producing lubricants, it is allowed to use as a dispersion medium a mixture of AC oils from low-sulfur or sulfur oils and industrial I-50A with a pour point not exceeding minus 20 ° C.
(Changed edition, Amendment No. 4).
1.2. The lubricant must comply with the requirements of this standard and be manufactured using the technology used in the manufacture of lubricant samples that have been tested with positive results and approved for use in the prescribed manner.

(Changed edition, Amendment No. 3, 4).
2. ACCEPTANCE RULES
2.1. The lubricant is taken in batches. A batch is considered to be any quantity of lubricant produced in a technological cycle, uniform in its quality indicators and accompanied by one quality document.
(Changed edition. Amendment No. 3).
2.2. The volume of samples is in accordance with GOST 2517.
2.3. If unsatisfactory test results are obtained for at least one of the indicators, a re-test of a newly selected sample of the same sample is carried out.
The results of repeated tests apply to the entire batch.
3. TEST METHODS
3.1. Lubricant samples are taken according to GOST 2517. The mass of the combined lubricant sample is 2 kg.
(Changed edition, Amendment No. 2).
3.2. To determine the appearance, the lubricant is applied to a plate with dimensions of 50x70x2 mm made of glass according to GOST 111 or other colorless transparent glass using a template made of non-corrosive metal, thickness (2±0.1) mm (drawing). Maximum deviations of template dimensions are ±1 mm. The template is tightly applied to the plate, first the inner edges of the template hole are wrapped using a spatula, and then all template holes are filled with a layer of lubricant above the thickness of the template. The lubricant is compacted with a spatula, excess lubricant is removed with a rib, the template is carefully removed from the plate and viewed in transmitted light with the naked eye. The presence of a fine-grained structure is not a rejection sign.
(Changed edition, Amendment No. 4).
3.3. (Deleted, Change. No. 4).
4. PACKAGING, LABELING, TRANSPORTATION AND STORAGE
4.1. Packaging, labeling, transportation and storage are carried out in accordance with GOST 1510 with the following addition:
It is allowed to pack the lubricant into steel barrels with a removable bottom with a capacity of 50 and 200 dm 3.
The lubricant must be stored in the manufacturer's container.
5. MANUFACTURER WARRANTY
5.1. The manufacturer guarantees that the lubricant meets the requirements of this standard subject to the conditions of transportation and storage.
(Changed edition, Amendment No. 2).
5.2. The guaranteed shelf life of the lubricant is five years from the date of manufacture.
The service life of the lubricant in time is five years, in terms of mileage - 500 thousand km, allowed until 01/01/93 - 450 thousand km.
(Amended edition, Rev. No. 1,2. 4).
6. SAFETY REQUIREMENTS
6.1. The lubricant does not contain toxic substances that affect the health of operating personnel. When working with lubricants, it is necessary to use personal protective equipment in accordance with standard industry standards approved by the USSR State Committee for Labor and Social Issues and the Central Committee of the All-Union Central Council of Trade Unions.
(Changed edition, Amendment No. 2).
6.2. The grease is explosion-proof. Flash point above 200 °C. When a lubricant spills, the spill site is covered with sand and then removed.
6.3. Persons working with lubricants should wash their hands with warm water and soap before eating, smoking and after finishing work.
6.4. If the lubricant catches fire, the following fire extinguishing agents are applicable: carbon dioxide, SRC composition, composition 3, 5 and superheated steam.
6.5. The room in which work with lubricants is carried out must be equipped with supply and exhaust ventilation.
6.3-6.5. (Introduced additionally, Amendment No. 1).
