Precast concrete flags, kerbs, channels, edgings and quadrants - Part 1: Precast, unreinforced concrete paving flags and complementary fittings - Requirements and test methods

Requirements and test methods for precast, unreinforced concrete paving flags and complementary fittings.

This part of BS 7263 specifies requirements and test methods for precast, unreinforced concrete paving flags and complementary fittings. This British Standard specifies the dimensions of rectangular paving flags designated in the United Kingdom, and the dimensions and shapes of tactile paving flags. It is applicable to precast, unreinforced concrete paving flags and complementary fittings that are particularly for use in external trafficked paved areas.

The specific changes included in this revision are the following:

a) the dimensional requirements have been removed so that paving flags can be of any shape or size (the shapes and sizes in the previous edition have been retained as designated units);

b) the water absorption limit has been removed;

c) the bending load requirement has been replaced by a bending strength requirement and the test method has been modified accordingly;

d) performance requirements and test methods have been added for:

- weathering resistance (freeze/thaw);

- abrasion resistance;

- slip/skid resistance;

- visual properties;

e) for weathering resistance, abrasion resistance and slip/skid resistance, performance classes have been introduced.

This British Standard together with BS 7263-3:2001 supersedes BS 7263-1:1994 which is withdrawn.

This standard includes the following cross references:

BS 812-114:1989, BS 7932:1998, BS EN 10083-2:1991, BS EN ISO 4288:1998,
