Overview

Introducing the BS ISO 16938-1:2019, a pivotal standard in the realm of buildings and civil engineering works. This document is essential for professionals who are involved in the construction and maintenance of buildings and civil engineering projects. It provides a comprehensive methodology for determining the staining of porous substrates by sealants used in joints, specifically through a test with compression.

Why This Standard is Essential

In the construction industry, the integrity and aesthetics of materials are paramount. Porous substrates, such as concrete, stone, and brick, are commonly used in construction due to their durability and aesthetic appeal. However, these materials are susceptible to staining, which can compromise both their appearance and structural integrity. The BS ISO 16938-1:2019 standard addresses this critical issue by providing a reliable method to assess the potential for staining caused by sealants.

Key Features

• Comprehensive Testing Methodology: The standard outlines a detailed procedure for testing the staining potential of sealants on porous substrates. This includes specific conditions and parameters to ensure accurate and consistent results.
• Focus on Compression: The test method involves the application of compression, which is a common stressor in real-world applications. This ensures that the results are relevant and applicable to actual construction scenarios.
• Applicable to Various Materials: The standard is versatile and can be applied to a wide range of porous materials, making it a valuable tool for diverse construction projects.

Benefits of Using BS ISO 16938-1:2019

Adopting the BS ISO 16938-1:2019 standard offers numerous benefits to construction professionals:

• Enhanced Material Longevity: By identifying sealants that may cause staining, professionals can make informed decisions to select materials that will maintain their appearance and integrity over time.
• Improved Aesthetic Outcomes: Staining can significantly detract from the visual appeal of a building. This standard helps ensure that the aesthetic quality of construction projects is preserved.
• Cost Efficiency: Preventing staining can reduce the need for costly repairs and maintenance, leading to long-term savings.
• Compliance and Quality Assurance: Utilizing this standard demonstrates a commitment to quality and compliance with international best practices, enhancing the reputation of construction firms.

Who Should Use This Standard?

The BS ISO 16938-1:2019 standard is indispensable for a wide range of professionals in the construction industry, including:

• Architects: To ensure that the materials specified in their designs will not suffer from unsightly staining.
• Engineers: To verify that the structural integrity of materials is not compromised by sealant-induced staining.
• Construction Managers: To oversee the selection and application of sealants in a manner that prevents staining.
• Quality Assurance Professionals: To implement testing protocols that align with international standards.

Conclusion

The BS ISO 16938-1:2019 standard is a critical resource for ensuring the durability and aesthetic quality of construction projects. By providing a reliable method for assessing the staining potential of sealants on porous substrates, it empowers professionals to make informed decisions that enhance the longevity and appearance of their work. Whether you are an architect, engineer, or construction manager, this standard is an invaluable tool in your professional toolkit.

• 91.100.50 Binders. Sealing materials

This document specifies a method for determining the staining of porous substrates (e.g. marble, limestone, sandstone or granite) by sealants used in building construction. The method evaluates the likelihood of a sealant causing an early stain on a porous substrate due to exudation of materials from the sealant. The outcome of the test is specific to the tested sealant and tested substrate and cannot be extrapolated to other sealant formulations or other porous substrates. During this accelerated test, if the sealant does not stain or discolour the substrates, it does not mean that the tested sealant will not stain or discolour the tested porous substrate over a longer time period.
