The size of the gaps between the mineral wool strips is determined after every fifth strip of the measured product. (Changed edition, Rev. 1, 2) The difference in thickness is determined by the results of measuring the thickness of the mats according to n The difference in thickness is calculated as the difference between the largest and smallest values of the mat thickness The width of the longitudinal edge is measured with an error of up to 1 mm in six places and is calculated as the arithmetic mean of the measurements made Density determined without taking into account the cover material according to GOST (Changed edition, Rev. 1, 2) The compressibility of the mat is determined according to GOST From each mat that fell into the sample according to clause 3.1, two samples are cut out together with the cover material The thermal conductivity of the mat is determined according to GOST From each mat , selected according to clause 3.3, are cut out in one sample without cover material. The moisture content of the mat is determined according to GOST. selection by n The strength of gluing mineral wool strips to the cover material is determined by inspection and after rolling it into a roll twice and then unrolling it on a flat surface. The mat is deemed to have passed the test if, after the second unrolling and turning the mat with the strips down, no strip is completely separated from the covering material. 7

8 (Revised edition, Rev. 2). 5. PACKAGING, MARKING, TRANSPORTATION AND STORAGE 5.1. Packing, marking, transportation and storage of mats is carried out in accordance with the requirements of GOST and this standard. (Revised edition, Rev. 2). 5.la. Mats must be rolled up. Roll weight - no more than 50 kg, roll diameter - no more than 400 mm. Mats up to 1500 mm long can be delivered unfolded in stacks. The foot is wrapped with a strip of paper, the end of the paper web is sealed. Foot mass - no more than 50 kg, foot height - no more than 500 mm. Transport packages are formed in accordance with the rules for the carriage of goods, package sizes and packaging means - according to GOST (Introduced additionally, Amend. 2) It is allowed to transport mats in open vehicles at a distance of up to 200 km with mandatory covering them with tarpaulin or other moisture-proof material. Transportation of mats by rail is carried out by carload shipments. Transport marking is carried out with the application of the manipulation sign “Afraid of dampness” in accordance with GOST The height of the stack during storage should not exceed 2 m. eight

Date of introduction 01.07.79

1. GRADES AND SIZES

1.1. Mats, depending on the density (bulk weight), are divided into grades 75 and 125.

1.2. The dimensions of the mats must correspond to those given in table. 1 and in the drawing.

An example of a symbol for a mat of grade 75 on glass roofing material of grade S-RK, 3000 mm long, 1000 mm wide and 60 mm thick:

Table 1

(Changed edition, Rev. No. 1, 2).

1 - cover material; 2 - mineral wool strips

2. TECHNICAL REQUIREMENTS

2.1. Mats must be manufactured in accordance with the requirements of this standard according to the technological regulations approved in the prescribed manner.

2.2. For the manufacture of mats, mineral wool slabs on a synthetic binder grades 75 and 125 according to GOST 9573 should be used.

(Revised edition, Rev. No. 1).

2.3. The following protective materials should be used: roofing material according to GOST 10923, glass roofing material according to GOST 15879, aluminum foil dubbed, fiberglass roll for thermal insulation and foil roofing material according to the manufacturer's specifications.

As an adhesive, bitumen grades BN70/30 and BN90/10 according to GOST 6617, polyethylene film according to GOST 10354 are used.

Note. It is allowed, by agreement between the manufacturer and the consumer, to use other coating and adhesive materials.

2.4. The maximum deviations of the dimensions of the mats should not exceed:

The variation in the thickness of the mat should not exceed 5 mm.

2.3; 2.4.

2.5. The gap between the mineral wool strips that make up the mat s should not exceed 2 mm.

2.6. According to physical and mechanical indicators, mats must meet the requirements specified in Table. 2.

table 2

2.7. Mats must withstand the test for the strength of bonding mineral wool strips to the cover material, provided for in clause 4.10.

2.6, 2.7. (Revised edition, Rev. No. 2).

3. ACCEPTANCE RULES

3.1. Acceptance of mats should be carried out in accordance with the requirements of GOST 26281 and this standard.

3.2. The batch volume of mats is set in the amount of no more than a shift output.

Thermal conductivity is determined once a quarter and with each change in raw materials and production technology on three mats that have passed acceptance tests.

Upon receipt of satisfactory results for three consecutive batches, it is allowed to carry out periodic control according to clause 3.3.

Sec. 3. (Revised edition, Rev. No. 2).

4. TEST METHODS

4.1, 4.2. (Deleted, Rev. No. 1).

4.5. The width of the longitudinal edge is measured with an error of up to 1 mm in six places and is calculated as the arithmetic mean of the measurements taken.

4.6. Density is determined without taking into account the coating material according to GOST 17177.

(Changed edition, Rev. No. 1, 2).

4.7. The compressibility of the mat is determined according to GOST 17177.

From each mat included in the sample according to clause 3.1, two samples are cut out along with the cover material.

4.8. The thermal conductivity of the mat is determined according to GOST 7076.

From each mat selected according to clause 3.3, one sample is cut out without cover material.

4.9. The moisture content of the mat is determined according to GOST 17177.

4.10. The adhesion strength of mineral wool strips to the cover material is determined by examining the mat after it has been rolled up twice and then unfolded on a flat surface.

The mat is deemed to have passed the test if, after the second unrolling and turning the mat with the strips down, no strip is completely separated from the covering material.

5.2. It is allowed to transport mats in open vehicles at a distance of up to 200 km with obligatory covering them with a tarpaulin or other moisture-proof material.

Transportation of mats by rail is carried out by carload shipments. Transport marking is carried out with the application of the handling sign "Keep away from moisture" in accordance with GOST 14192.

5.3. The height of the stack during storage should not exceed 2 m.

5.4. The holding time of mats in the warehouse before shipment to the consumer must be at least one day.
