Transmission and Conveyor Belts Testing

One category of products driving every industry in one form or other are the Belts. From drive systems for standard and special purpose machines, domestic appliances, process industry lines, Food and Beverage industries, Mining, Quarries, Agricultural industries and many more, the belts play role in the system. Standardization and quality norms of these products are defined in National and International standards. Maeon Laboratories provide testing services for products including V belt testing, Timing belt testing, Power transmission belt testing, conveyor belt testing, safety belt testing to such standard test methods, some listed here.

Ageing Tests for Belts

The influence of prolonged heat over the physical properties are of importance for belts. The standards used for testing these properties at Maeon Laboratories is given above

Resistance to contact of belt material with different fluids is determined for quality control and for development purposes.

	Heat Resistance of Cover	ISO 4195
BL1GE-10	Liquid Ageing	ASTM D471

Coefficient of Friction for Belts

Belt friction is developed when the friction forces act between a belt and another surface in contact. This test involves determination of the coefficients of starting and sliding friction of belt rubber material when sliding over itself or other substances. An important property in the industry as energy or material transfers all involve frictional forces.

BL1GE-6	Coefficient of friction, belt friction	ASTM D1894, ASTM D378, ISO 21182, IS 16365

Abrasion Resistance of Belts

Abrasive or frictional wear of the belts in service is the main cause of failure of conveyor and transmission belts. An estimation of resistance to wear is specified in standards of belts, which must be controlled. Maeon laboratories provide services for testing of Abrasion resistance.

BL1GE-7	Abrasion resistance, Abrasive loss of cover	ASTM D5963, ASTM D378, IS 1891-1

Electrical Resistance tests

Conveyor belts demand high level electrical resistance for most applications. A measurement and compliance of this character is mandatory in many standards of conveyor and other types of belts. Electrical conductivity is determined in antistatic V belts, wide section belts and conveyor belts.

BL1GE-9	Electrical Resistance, Surface Resistance	ASTM D378, IS 3181, ISO 21178 , ISO 21179, IS 16382, IS 16381
	Electrical Conductivity – Antistatic belts	ISO 284, ISO 1813, IS 15138, ISO 9563, IS 16378

Environmental Tests

Exposure of the belts to atmosphere leads to attack by Ozone, leading to cracks. The laboratory tests involve, sample to be under surface tensile strain conditions, either dynamic or static, in an atmosphere containing specified levels of ozone concentration and its effect on the surface is estimated.

BL1GE-8	Ozone Resistance	ASTM D1149, ASTM D378

Adhesion Tests - Belts

Transmission belts, conveyor belts , v belts are made with many plies of fabric that are adhered to each other using inner layers of elastomers.

Belts operate on equipment that requires repeated flexing over pulleys on the conveyor or rollers. This repeated flexing action stresses the ply adhesion of conveyor belts. Hence, it is important for the belt to have adequate ply adhesion to resist ply separation to avoid costly failures of the systems.

Maeon Laboratories perform the Adhesion tests by determining the adhesion strength between plies of fabric bonded with rubber or the adhesion of the rubber layer in V belts, conveyor belts, other transmission belts.

	Edge adhesion	IS 3181

Flammability Tests - Belts

Fire retardancy requirement of belts is undoubtedly essential for any industries, especially it is so in mining, for transport of materials under high temperature and for materials prone to ignite. Fire resistant conveyor belts are essential in avoiding fire hazards.

International and national standards specify the test method to assess FR grade category or Flammability Characteristics of the belt materials. Above some standards Maeon laboratory follow for this Flame Resistance testing of Belts.
