2. ACCEPTANCE RULES

2.1. Roofing petroleum bitumens are accepted in batches. A batch is any amount of bitumen that is uniform in quality indicators and accompanied by one quality document. 

2.2. Sample size - according to GOST 2517. 

2.3. The manufacturer determines the mass fraction of water periodically at least once every 6 months.

Solubility in toluene or chloroform and the mass fraction of paraffin are determined periodically at least once every 3 months..

If unsatisfactory results are obtained from periodic tests, the manufacturer transfers the tests for this indicator to acceptance tests until positive results are obtained for at least three consecutive batches.

(Amended version, Amendment No. 4).

2.4. If unsatisfactory test results are obtained for at least one indicator, repeat tests are carried out on a newly selected sample from a doubled selection. The results of the repeat tests apply to the entire batch.

3. TEST METHODS

3.1. Samples of roofing petroleum bitumen are taken in accordance with GOST 2517. The mass of the combined sample of bitumen of each grade is 0.5 kg.

(Amended version, Amendment No. 3).

4. PACKAGING, MARKING, TRANSPORTATION AND STORAGE

4.1. Packaging, marking, transportation and storage of roofing bitumens according to GOST 1510. Transportation of roofing bitumens in tank trucks and bunker gondola cars is permitted. 

4.2. Petroleum roofing bitumens belong to the 9th class of transport hazard according to GOST 19433 (subclass 9.2, category 9.21, classification code 921).

(Additionally introduced, Amendment No. 5).

5. MANUFACTURER\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'S WARRANTY

5.1. The manufacturer guarantees that roofing petroleum bitumens comply with the requirements of this standard. 

5.2. The guaranteed shelf life of roofing petroleum bitumens is one year from the date of manufacture.

5.1, 5.2. (Amended version. Amendment No. 3). 

6. SAFETY REQUIREMENTS

6.1. Petroleum roofing bitumens are flammable substances with a flash point of at least 240 °C. The minimum autoignition temperature is 300 °C according to GOST 12.1.044. 

6.2. Petroleum bitumens are low-hazard substances and, in terms of their impact on the human body, belong to hazard class 4 according to GOST 12.1.007. Fumes of molten bitumen have a moderate irritating effect on the skin and mucous membranes of the eyes and upper respiratory tract. The cumulative effect is not pronounced. 

6.3. The maximum permissible concentration of petroleum bitumen vapors is adopted for aliphatic hydrocarbons C1 - C10 (in terms of C) and is 300 mg/m3 in the air of the working zone according to GOST 12.1.005. The content of hydrocarbon vapors in the air is determined by the chromatographic method.

6.4. Petroleum bitumens do not form toxic compounds in the air and waste water in the presence of other substances or factors.

6.5. Those working with petroleum bitumen must be provided with personal protective equipment in accordance with standard industry standards for the issuance of special clothing, special footwear and other personal protective equipment: filter gas masks according to GOST 12.4.034*, suits according to GOST 12.4.111 and GOST 12.4.112, footwear according to GOST 12.4.032, gloves according to GOST 12.4.010 and protective glasses according to GOST 12.4.013**. There are no special requirements for personal hygiene.

6.6. If heated petroleum bitumen gets on exposed areas of skin, it must be cooled under running water, the bitumen must be removed with petroleum jelly, and the victim must be given assistance as for thermal burns.

6.7. The room in which work with bitumen is carried out must be equipped with supply and exhaust ventilation.

6.8. If small quantities of bitumen catch fire, extinguish with sand, felt or a foam fire extinguisher. Extinguish developed fires with a foam jet.

6.9. Bitumen production waste - oxidation gases - are rendered harmless by burning in an afterburner.
