SN 1549-2011Technical code for control and supervision on extraneous impurity in coal for import and export (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

Instead of the standard SN/T 1549-2005 "foreign matter in coal import and export control and supervision of the technical specifications." This revision, while retaining SN/T 1549-2005 original content, and further complements the inspection and quarantine supervision content.

This standard compared with SN/T 1549-2005 The main changes are as follows.

--- Content changed mandatory;

--- The definition of foreign debris, according to their impact safety, hygiene, health, the degree of environmental protection, classified as A, B, C three types of debris (see 3.1);

--- Magnetic iron absorption equipment, all to "suck iron ore by a magnetic device" was defined;

--- Chapter 4 of the title from "foreign imported coal debris regulatory requirements" to "foreign imported coal debris control and regulatory requirements";

--- Foreign matter in coal import control requirements from the "coal imports should not be mixed with foreign matter" to "coal imports should not be mixed 3.1 listed in Class A and Class B debris, mixed with some 3.1 class included C Debris shall not exceed 0.01% by weight of the coal. " (See 4.1), and a corresponding increase in foreign matter content is calculated (see 4.3);

--- Increased imports of coal storage pollution prevention requirements (see 4.4);

--- Increased imports of coal inspection and quarantine regulatory requirements (see 4.5);

--- Increased coal export inspection and quarantine regulatory requirements (see 5.1.7 and 5.2.4);

--- Increased coal import and export inspection and supervision results to determine foreign materials and unqualified disposal requirements (see Chapter 7).

3 Terms and Definitions

The following terms and definitions apply to this document.

Foreign debris extraneousimpurity in the process of coal mining, production, processing, storage, transportation and other impurities mixed in, according to their impact safety, hygiene, health, environmental Cheng Degree, can be divided into A, B, C three types of debris.

1) A type of debris, that the risk of debris, including residual detonators mining process unexploded, combustible gun line, as well as other flammable Toxicity class or foreign matter.

2) Class B debris that quarantine type of debris, including support with woods, bark, wood, wedge, etc., transportation and storage of mixed the weeds, straw, rope, straw bags, garbage, etc., soil, animal carcasses and other animal debris, and other quarantine class Extraneous matter.

3) Class C debris, that in addition to the risk of debris and other debris quarantine class foreign matter, including the mining process have been detonated detonator Leather (detonator head), the production process waste miscellaneous iron (eg component wire, spikes, welding rod, bolts, welding slag and other equipment, etc.), Large pieces of waste rock, plastic (such as plastic bags loaded with explosives, transportation and storage of instant noodles mixed bags and other plastic packaging Etc.), fiber (such as yarn, silk, wire rope, woven bags, cement bags, boxes, etc.), paper (such as explosives, wrapping paper, cardboard boxes and Cardboard, etc.), transportation and storage of mixed shoe, sand, stones, and other non-hazardous and non-quarantine outside the class to impurities.
