Read what the code covers

Each card states the real scope — so you can tell a calculation standard from a component standard or a safety standard.

3

Open the official source

Every card links to the issuing body (ISO, CEN, DIN, CEMA, SAMR, Rosstandart, SABS, eCFR). We never republish standard text.

Which standard applies where

The short answer, by market — the detail sits in the cards above it.

Region	Codes that govern there
International	ISO 5048 · ISO 1537 · ISO 15236-1 · ISO 340 · ISO 9001 Cross-border tenders and specs written to be neutral between US, EU and Asian practice.
Europe	EN 620 · DIN 22101 · DIN 22102-1 · DIN 22107 CE-marked projects and German-speaking plants; EN 620 is the safety hook for CE marking.
North America	CEMA Belt Book · MSHA 30 CFR Part 14 US and Canadian bulk handling; MSHA Part 14 applies only to underground coal mines.
China	GB/T 10595 · MT 820 · MT/T 821 · MA approval Domestic projects and coal mines; the MA mark is compulsory underground.
Russia & CIS	GOST 22644 · GOST 31558 Mining and port projects in Russia and Kazakhstan.
Asia-Pacific	AS/NZS 4024.3611 Australian and New Zealand bulk materials handling.
Africa	SANS 971 South African mining belt specification and fire-retardance testing.

Questions buyers ask us

Short answers to the ones that come up in almost every enquiry.

Which standard applies to belt conveyors in Europe?

EN 620:2021 covers the safety of fixed belt conveyors for bulk materials and is harmonised under EU machinery law. For calculation, DIN 22101 is the widely used European basis; DIN 22102-1 covers textile belts and DIN 22107 gives idler-set dimensions.

Is ISO 5048 still current?

Yes. ISO 5048:1989 has been reviewed and confirmed and remains the international reference for calculating driving-pulley power requirements and the tensile forces in the belt.

Which standard applies to belt conveyors in the United States?

There is no single US conveyor standard. Design practice follows the CEMA “Belt Conveyors for Bulk Materials” book, and underground coal mines additionally require flame-resistant belts approved under MSHA 30 CFR Part 14.

Which Chinese standard covers belt conveyor idlers and pulleys?

GB/T 10595-2017, “Belt conveyors”. The older GB/T 988 (pulleys) and GB/T 990 (idlers) were withdrawn on 2009-11-01 and their content was merged into GB/T 10595. For coal mines, MT 820 and MT/T 821 apply together with the compulsory MA safety approval mark.

Which standard applies in Russia and the CIS?

GOST 22644 defines the basic parameters and dimensions of belt conveyors. For mine conveyors in gas- or dust-hazardous conditions, GOST 31558-2012 is the governing specification.

Is JIS B 8804 a belt conveyor standard?

No. JIS B 8804:1995 is “Steel roller conveyors” — roller conveyors for boxes and unit loads. It is frequently misquoted as a Japanese belt-conveyor standard, but it does not cover belt conveyors.

Do you supply to Australian or South African requirements?

Yes. AS/NZS 4024.3611:2015 is the current conveyor safety part for Australia and New Zealand, and SANS 971 covers fire-retardance testing of conveyor belting used by South African mines.

Codes we see quoted wrongly

Three codes turn up regularly in tenders and on vendor pages with the wrong description. Check before you buy:

JIS B 8804:1995: “Steel roller conveyors” — roller conveyors for boxes and unit loads, not belt conveyors. It is widely misquoted as the Japanese belt-conveyor standard; there is no JIS code that plays that role.
GOST R 54385-2011: “Green (raw) coffee — olfactory and visual examination”. It is a cancelled food standard and has nothing to do with conveyors. The correct Russian reference for mine belt conveyors is GOST 31558-2012.
GB/T 988 / GB/T 990: Frequently sold today as “current idler and pulley standards”. Both were withdrawn on 2009-11-01 and their content now sits inside GB/T 10595. GB/T 988 covered pulleys, GB/T 990 covered idlers.
