GB/T 5752-2013Conveyor belts -- Marking (English PDF)

Foreword

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

This standard replaces GB/T 5752-2002 "conveyor belt sign", compared with the GB/T 5752-2002, the main technical changes are as follows.

--- Modify the scope of application (see Chapter 1, Chapter 1 of the 2002 edition);

--- Modify the definitions of terms (see Chapter 3, Section 3 of the 2002 edition);

--- Remove the conveyor belt core material and letter code (see 2002 edition 4.6);

--- Deleted layered fabric conveyor belt with a core layer (see 2002 edition 4.7);

--- Remove the conveyor belt, under the cover layer thickness (see 2002 edition 4.8);

--- Modify the maximum interval of the entire broadband logo (see 521, 2002 edition of 5.2.1.);

--- Modified exemplary flag (see Chapter 6, Section 6 of the 2002 edition).

This standard uses redrafted law revision using ISO 433:1991 "conveyor belt sign." this standard and ISO 433:1991 technical differences exist compared to the terms of these differences have been involved in the blank position by its outer margin Vertical single line (|) have been marked, and the technical differences for the following reasons.

--- According to GB/T 1.1-2009 provides added range "This standard applies to all kinds of transportation in addition to the light conveyor belt band. "(See Chapter 1).

Love --- on normative references, this standard has been adjusted technical differences, in order to adapt to China's technical conditions, adjustment Focus is reflected in the status of Chapter 2, "Normative references", the specific adjustments are as follows.

- equivalents adoption of international standards GB/T 3690 instead of ISO 283 (see 4.1);

- equivalents adoption of international standards GB/T 3684 instead of ISO 284 (see 4.2);

- equivalents adoption of international standards GB/T 3685 instead of ISO 340 (see 4.2);

- Remove the ISO 3166;

--- According to China's actual conditions modify the content of the flag (see 4.4);

--- According to China's actual conditions modified exemplary flag (see Chapter 6).

This standard also made the following editorial changes.
