This part is part 19 of GB/T 13477.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
Part 1. GB/T 13477.19-2002 "Test methods for building sealants - Part 19. Determination of changes in mass and volume
Set ", compared with GB/T 13477.19-2002, the main technical changes are as follows.
- modified scope, increased the expression of non-applicable content (see Chapter 1, Chapter 1 of the.2002 edition);
- increased the expression of the balance in the test apparatus and the level of the test reagent, and removed the specific balance (see 5.5 and 5.1,.2002)
5.5, 5.6 and 5.7);
- modified specimen preparation (see Chapter 6, Chapter 6 of the.2002 edition);
- modified the test procedure (see Chapter 7, Chapter 7 of the.2002 edition);
--- modified the results of the calculation, an increase of the results that (see Chapter 8,.2002 edition of Chapter 8);
- modified the test report [see column 9 a), c), d) and e), chapter 9 b) and c) of the.2002 edition.
This part uses the translation method equivalent to ISO 10563..2005 "building structure sealing material quality and volume change determination".
In this part of the normative reference to the international documents have a consistent correspondence between the following documents.
Glossary of Building Sealants (ISO 6927. 1981, NEQ) GB/T 14682-2006.
This section makes the following editorial changes.
- in line with this series of standards, the standard name to "building seal material test method Part 19. quality and volume changes
Of the determination ";
- Removed "(see 6.2)" in column eart. E) of ISO 10563..2005;
- in the ISO 10563..2005 Chapter 9 item e), change the "single change in the quality of each specimen and volume change" to "every test
Mass change and/or volume change.

Test methods for building sealants
Part 19. Determination of changes in mass and volume
1 Scope
This part of GB/T 13477 specifies the method for determining the quality change and volume change of the sealing material for building joints.
This part does not apply to self-leveling seals.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.

Sealants-Vocabulary)
3 terms and definitions
The terms and definitions defined in ISO 6927 apply to this document.
4 principle
The sealing material is filled with the metal ring to form the test piece, placed at room temperature and high temperature to handle, measure and record the temperature before and after the test piece quality
And/or the difference in volume.
5 utensils and materials
5.1 Corrosion-resistant metal ring. the size of about 34mm diameter, diameter 30mm, high 10mm. The ring is fitted with a hook or spring for weighing
Hanging on the thread.
5.2 Anti-blocking material. used to prepare test pieces, such as wet paper.
5.3 Maintenance tank. can control the temperature (23 ± 2) ℃ and relative humidity (50 ± 5)%.
5.4 Blow drying oven. can control the temperature (70 ± 2) ℃.
5.5 balance. scale value of 0.01g, used to weigh the specimen in the air and in the water quality.
5.6 Test liquid. temperature (23 ± 2) ° C, consisting of water and less than 0.25% (mass fraction) of low foaming surfactant. for
Water-sensitive sealing material, should use the experimental grade 2,2,4-trimethylpentane (isooctane).
5.7 Containers. used to soak the test piece in the test liquid.
6 Preparation of test pieces
6.1 The sealing material and the metal ring shall be placed at (23 ± 2) ° C, and each test piece shall be prepared for each test property.
6.2 Use the balance (5.5) to weigh the mass (m1) of each metal ring in the air. For volume determination, it should also be weighed in test liquid (5.6)
