What is BS EN 12227 1999 ?

Title: What is BS EN 12227 1999 and BS EN 13139: 2002?

Introduction:

BS EN 12227 1999 and BS EN 13139: 2002 are two technical standards that provide guidelines and specifications for the production and application of mortar intended for masonry construction and asphalt mixtures. respectively. These standards were developed by the British Standards Institution (BSI) in collaboration with other European committees to ensure high-quality mortar and asphalt products that meet the necessary requirements for durability and performance.

Purpose of BS EN 12227 1999 and BS EN 13139: 2002:

The primary purpose of BS EN 12227 1999 and BS EN 13139: 2002 is to establish uniform testing methods and performance criteria for mortar and asphalt mixes used in masonry construction and road construction. respectively. By following these standards. manufacturers can ensure that their mortar and asphalt products comply with industry requirements and are safe for use in various building and transportation applications.

Key Requirements and Specifications:

BS EN 12227 1999 and BS EN 13139: 2002 provide specific requirements and specifications for the properties and performance of mortar and asphalt mixes. These requirements are divided into two main categories:

1. Mortar:

Mortar is a mixture of cement. sand. and water. which is used to hold building materials together. The key requirements and specifications for mortar. as outlined in BS EN 12227 1999 and BS EN 13139: 2002. include:

a. Composition: Mortar must be made up of at least 60% cement. 10% sand. and 30% water.

b. Consistency: Mortar must be consistent in terms of its physical. chemical. and mechanical properties.

c. Workability: Mortar must be able to be mixed. shaped. and molded to create a desired profile and surface finish.

d. Adhesive strength: Mortar must have an adhesive strength of at least 10MPa (megapascals) when tested at 28 days' exposure.

e. Durability: Mortar must be able to withstand the effects of weathering. water. and other environmental factors. with a life expectancy of at least 12 months.

2. Asphalt mixtures:

Asphalt mixtures are used to pave roads and other transportation infrastructure. and are made up of a combination of asphalt. cement. sand. and water. The key requirements and specifications for asphalt mixtures. as outlined in BS EN 12697-24. include:

a. Composition: Asphalt mixtures must be made up of at least 70% asphalt. 10% cement. and 20% sand.

b. Test methods: Asphalt mixtures must undergo various tests. including the Asphalt Pavement Testing Method (ASTM) E-12697-24. to determine their physical and mechanical properties.

c. Performance characteristics: Asphalt mixtures must have a minimum asphalt content of 4% and a maximum asphalt content of 10%. as specified by ASTM.

d. Durability: Asphalt mixtures must be able to withstand the effects of weathering. water. and other environmental factors. with a life expectancy of at least 12 months.

Conclusion:

BS EN 12227 1999 and BS EN 13139: 2002 provide guidelines and specifications for the production and application of mortar and asphalt mixtures. respectively. These standards ensure that manufacturers produce high-quality mortar and asphalt products that are safe for use in various building and transportation applications. By following these standards. manufacturers can ensure that their products meet the necessary requirements for durability and performance. and are suitable for specific applications.
